You cannot add a ceiling point or chase a cable. A freestanding lamp, adhesive or a magnet plate is the route that leaves the paint alone. The Auraglow AG708 stands on a table at £9.99 and also has an always-on mode.

Charlie White (Charlie DIYte)Expert source
A dark cupboard or a landing that stays black until you find the switch is the usual reason to look for a motion sensor battery. On amazon.co.uk these twelve listings are small LED lights with a PIR sensor, for cupboards, stairs, halls and bedside tables. None is a burglar alarm, a siren or a smart-home detector. You tell a useful one from a frustrating one by the power source, whether it has a real night-only mode, the colour, and whether a lumen figure is even stated. Claims of 120 or 180 days are seller figures tied to a short duty cycle, and several review sets describe flat batteries much sooner. The cells are generally not in the box. The [motion sensor battery buying guide](/hub/burglar-protection/motion-sensor-battery/sub/motion-sensor-battery-buying-guide) separates puck, bar and lamp before you choose colour or cells. A motion sensor battery is a battery LED light that switches on when a PIR sensor sees movement. The twelve amazon.co.uk listings are bars, stick-on pucks and one table lamp. They are not intruder alarms, and they do not stand in for a handrail. Stick-on pucks, the 3.1 inch pack, and cover a hall or a cupboard door.

The best motion sensor batteries in detail
Our view
The Auraglow AG708 is a freestanding table lamp that comes on within about 6 feet and holds a warm glow for 20 seconds, staying lit while it still sees movement. Across 390 amazon.co.uk reviews at 4.6 stars, buyers describe it for night bathroom trips and as a side-table lamp, and several say the cells last a long time on the automatic setting. It also has a permanent on/off mode, which most of the stick-on pucks in this set do not list. It needs three AAA batteries, which are not in the box, and the listing gives no lumen figure. One buyer found it smaller than expected, and the sampled reviews treat it as a night light rather than a lamp you could read or work by. It is not water resistant, even though some people stand it in a bathroom. At £9.99 it is the top pick in this set because that review sample does not show a repeated failure, though 390 reviews is a much smaller base than the STAR-SPANGLED pucks.
Pros
- Comes on within about 6 feet and stays on while motion continues
- Permanent on/off mode as well as the 20-second automatic glow
- 4.6 from 390 amazon.co.uk reviews, with long cell life mentioned on auto
- Warm glow that reviewers use for night bathroom trips
- £9.99, and no cluster of dead units in the sampled reviews
Cons
- No lumen figure on the listing
- Too dim for task lighting, and smaller than one buyer expected
- Not water resistant
- Three AAA cells are not included
Best for: You want a warm bedside or landing lamp you can move, including during a power cut, and you do not need a stick-on cupboard bar.
Less suitable: You need a stated lumen output, a light fixed inside a wardrobe, or a fitting that can take bathroom spray.

Common questions
What power source does the Auraglow AG708 use?
The listing states the supply as 3× AAA, not included, and the power type as replaceable cells. The amazon.co.uk price in this comparison is about £9.99. That line is product data from the listing, not a measured runtime.
How far does the sensor reach?
The listing states detection of 6 feet. That figure is the seller's claim, not a distance measured for this comparison.
Is it suitable for a bathroom or wet area?
The listing says the light is not water resistant. Keep it out of shower spray and other wet zones.
Our view
The unbranded HRS-Lihgt1, the model code misspelt on the listing, is a four-pack of 20 cm USB-C bars at £12.99. Modes are auto at night, auto all day, always on and off, with stepless dimming from 10 to 100 percent by a long press. A full charge is stated as two to three hours. The colour is cold white, and neither lumens nor detection range nor a water rating appear in the listing fields. The rating is 4.6 from only 15 amazon.co.uk reviews. Those reviews call the bars practical under cabinets, sensitive, and easy to lift off a magnet to charge. They also say a bump can knock one off the plate. Fifteen reviews cannot show whether that magnet complaint repeats, so the star line is not evidence on the scale of the larger packs.
Pros
- Four 20 cm USB-C bars for £12.99
- Night auto, day auto, always on and off, plus stepless dimming
- Magnetic, so they lift off to charge
- 4.6 from the 15 reviews, which call the detection sensitive
Cons
- Only 15 amazon.co.uk reviews
- A bump can knock a bar off the magnet
- No lumen figure, no detection range and no water rating
- Generic listing, and the model code is misspelt
Best for: You want four cheap rechargeable bars under a cabinet and you can press them back onto the magnet if one is knocked.
Less suitable: You want a known lumen output, a large review sample, or a mount that stays put when a cupboard door bumps it.

Common questions
What power source does the Generic HRS-Lihgt1 use?
The listing states the supply as USB-C, built-in, and the power type as usb rechargeable. The amazon.co.uk price in this comparison is about £12.99. That line is product data from the listing, not a measured runtime.
How far does the sensor reach?
The listing does not state a detection distance. There is no measured range in this comparison, so the table leaves that cell blank.

The Oumida three-pack costs £8.99 and lists eight LEDs at up to 50 lumens, three colour temperatures, a built-in 600 mAh cell, and auto, on and off modes with dusk-to-dawn plus motion. The listing calls it moisture resistant, which is not an IP code, and the voltage line is 3.7 V. Only 11 amazon.co.uk reviews sit behind the 4.6 stars, so the praise for stairs and bathrooms is a thin sample and the runtime is not shown there. Reviewers call it a basic puck and like the magnetic or adhesive fit. There is no detection distance on the listing. At this price it is a spare set you can try, not a result you can lean on the way you can lean on thousands of STAR-SPANGLED reviews.
Pros
- £8.99 for three USB-rechargeable pucks
- Up to 50 lumens stated, with three colour temperatures
- Built-in 600 mAh cell and auto, on and off modes
- 4.6 stars, with easy magnetic or adhesive fitting in the short review set
Cons
- Only 11 amazon.co.uk reviews
- Runtime is not shown in that sample
- Moisture resistant is not an IP rating
- No detection distance on the listing
Best for: You want a cheap rechargeable puck to try on a stair or in a cupboard, and you accept that 11 reviews cannot show a pattern.
Less suitable: You want a large review sample, a stated sensor range, or a moisture claim you can treat as a bathroom rating.

The AmmToo ZN01 four-pack costs £15.09 and uses three AAA cells per puck, not included, at about 0.5 W and 4.5 V. The listing states PIR detection of 3–5 metres in low light and a warm-white output, with stick-on or magnetic mounting, and it is not water resistant. The amazon.co.uk line is 4.5 from 6,959 reviews, and the same count and overlapping text appear on the eight-pack, so those reviews are not a second independent sample. Buyers like the warm light on halls and stairs and the peel-and-stick size. The repeated complaint is daylight triggering that flattens the cells, with one update putting empty batteries at about a month. No lumen figure is stated, and dusk-only behaviour is not reliable on every unit in that review set.
Pros
- Warm white that reviewers use in halls and on stairs
- PIR listed at 3–5 metres in low light
- Stick-on or magnetic, and described as small
- 4.5 from 6,959 amazon.co.uk reviews, shared with the eight-pack
Cons
- Some units turn on in daylight and flatten the AAA cells
- One update reports batteries empty after about a month
- The 6,959 reviews are not independent of the eight-pack
- No lumen figure, and the cells are not included
Best for: You want four warm stick-on pucks for halls and stairs, and you will check that they stay off in daylight before you rely on the cells.
Less suitable: You need a proven night-only mode, a lumen figure, or a review count that is separate from the eight-pack listing.

Our view
The AmmToo zn01 eight-pack costs £18.04 and repeats the four-pack’s 4.5 from 6,959 reviews, including overlapping text, so it is not better evidenced than the four-pack. The bullets describe three AAA cells, not included, about 0.5 W, PIR at 3–5 metres in low light, warm white, and a body about 12 mm thin. The power line also says rechargeable, which conflicts with the AAA bullets, and the Amazon reviews do not establish a built-in cell. Daylight activation that drains the cells is the same complaint as on the four-pack. It is not water resistant, and there is no lumen figure. You pay £18.04 only if you actually need eight pucks, and you still buy the cells yourself.
Pros
- Eight warm-white pucks in one pack
- PIR listed at 3–5 metres in low light
- About 12 mm thin in the listing bullet
- Stick-on or magnetic, and reviewers mention stairs and halls
Cons
- Same 6,959 reviews as the four-pack, so not a separate sample
- Listing says rechargeable and also three AAA cells
- Daylight activation drains the cells
- £18.04, cells not included, no lumen figure
Best for: You want eight of the same warm AmmToo puck and you have already accepted the four-pack’s daylight-drain complaint.
Less suitable: You want a rechargeable light, an independent review count, or a lower price per puck than the four-pack.

The BLS T61 is a two-pack of USB-C rechargeable bars at £19.99, with 40 LEDs and a built-in 1,800 mAh cell. A bullet says 250 lumens and the technical table says 180 lumens at 7,000 K, so the output is not a single figure you can quote. Modes cover on, off, auto at night, and auto day and night, and the maker claims up to 120 days at 10 uses a day for 20 seconds, which is a seller duty cycle rather than a result from these reviews. From 367 amazon.co.uk reviews at 4.5 stars, buyers like the magnetic fit under stairs and in cupboards and say a light-use charge lasts weeks. Others wanted more brightness, found the white too cool, and saw the sensor work at about half the claimed 10 feet (about 3 metres). Heavy use that leaves the bar on for hours means charging after a few days. It is not water resistant, and there is no remote for the dimmer.
Pros
- USB-C rechargeable 1,800 mAh cell, so no loose AAA cells to buy
- Separate night auto and day-and-night auto modes
- 4.5 from 367 amazon.co.uk reviews
- Magnetic or adhesive fit that reviewers use in cupboards and under stairs
Cons
- Bullet says 250 lumens and the technical table says 180 at 7,000 K
- Cool white, and some buyers found it less bright than expected
- One buyer saw the sensor at about half the claimed 3 metres
- Not water resistant, and the 120-day line assumes 10 short uses a day
Best for: You want a rechargeable cupboard bar you can unclip to charge, and cool white is acceptable for a worktop or a wardrobe.
Less suitable: You want a warm 2 a.m. landing light, a single agreed lumen figure, or a bar you can leave on for hours without recharging.

The Demlaies N100 is a six-pack of USB-C pucks at £19.99, listed with a 120-degree PIR out to 5 metres that switches off after 20 seconds, and a magnetic plate you can lift off to charge. The maker claims up to 180 days from a two-hour charge, and the capacity in milliamp hours is not stated. The rating is 4.5 from 31 amazon.co.uk reviews. Early comments call the pucks bright, slim and sensitive in halls, and at least one unit would not charge properly. Reviewers had not confirmed the 180-day line, and the light is not dimmable even though a buyer expected that. It is not water resistant. Thirty-one reviews and a charging fault are a thin base for the dearest puck pack in the folder.
Pros
- Six USB-C pucks for £19.99, with a magnetic plate for charging
- PIR listed at 120 degrees and 5 metres, off after 20 seconds
- Early reviews call them bright and slim in halls
- 4.5 from 31 amazon.co.uk reviews
Cons
- At least one unit would not charge properly
- 180-day claim has no milliamp-hour figure and is not confirmed in reviews
- Not dimmable, despite a buyer expecting dimming
- Only 31 reviews, and not water resistant
Best for: You want several rechargeable pucks for a hall and you will test that each one charges before you stick the plates down.
Less suitable: You need a proven runtime, dimming, or a review sample larger than a few dozen.

The STAR-SPANGLED US-22B-YE3 is a 3.1 inch warm-white puck, sold as a three-pack for £8.49, that the listing says switches on within 16 feet in the dark and off after 20 seconds, at up to 80 lumens from eight LEDs. It is the best value here: 4.4 from 20,302 amazon.co.uk reviews, the largest sample in the folder, and several buyers use it as a night path to the bathroom or along a skirting board. The same reviews include a dead unit in a three-pack, and one buyer had only two of three working. There is no switch, so the cells have to come out if you want it off in a bag or a drawer. It takes three AA batteries, which are not included, and it is not water resistant. The volume of reviews is the reason to start here on price, with the dead-on-arrival complaint as the reason not to treat every puck in the pack as tested.
Pros
- £8.49 for three warm-white pucks, the lowest price in this set
- 4.4 from 20,302 amazon.co.uk reviews
- Listing states up to 80 lumens and a 20-second off in the dark
- Reviewers use it along skirting and on a night path to the bathroom
Cons
- One buyer received a dead light in the three-pack
- No off switch, so the AA cells have to come out to stop it
- Three AA batteries are not included
- Not water resistant
Best for: You want the cheapest warm puck in this set for a hall or a skirting run, and you can return a single dead unit.
Less suitable: You need every puck in the pack working on day one, or a light you can switch off without removing the cells.

The Detake LD064-WH is a two-pack at £13.49, each unit running on one AA cell that is not in the box. In the dark it is listed to sense within 10 feet (about 3 metres) across 120 degrees and to switch off after 30 seconds, with seven LEDs at about 4,000 K. Across 3,949 amazon.co.uk reviews at 4.4 stars, people praise the brightness for stairs, a dark hall and an older relative, and one household mentions a cat crossing at night. The serious complaint is power: one household changed batteries every three or four days, another note describes a flat battery overnight, and a rechargeable AA lasted about two weeks in a buyer comment. There is no low-battery indicator, and the listing does not state lumens or a water-resistance code. It suits a quiet landing better than a busy hall if you do not want to keep spare AAs in the drawer.
Pros
- Night-only auto listed at 10 feet, 120 degrees, off after 30 seconds
- About 4,000 K, warmer than the 7,000 K bars in this set
- 4.4 from 3,949 amazon.co.uk reviews
- Reviewers use it on stairs and for an older relative at night
- One AA cell per unit, so a change is quick
Cons
- One household changed batteries every three or four days
- No low-battery indicator
- No lumen figure and no water-resistance code
- The AA cell is not included
Best for: You want a stick-on night light for a quiet stair or hall, and you can accept buying AA cells more often if the route is busy.
Less suitable: You need a stated lumen figure, a low-battery warning, or cell life measured in months on a busy landing.

The STAR-SPANGLED US-22A-YE3 is a 7 inch warm bar, three to a pack at £9.99, listed at up to 80 lumens with a sensor that works in the dark and switches off after 20 seconds, out to 16 feet. The head swivels about 90 degrees, which reviewers use to aim the beam inside a wardrobe or down a stair. At 4.3 from 3,338 amazon.co.uk reviews, several people say the on-off behaves as expected and that the cells last a long time, though one buyer found the PIR unreliable. The housing is described as cheap plastic, and three AAA cells per bar, not included, is a lot of batteries for a short bar. It is not water resistant. It sits just behind the top pick on review cleanliness, and behind the best value puck on price and sample size.
Pros
- Up to 80 lumens stated, with a 90-degree swivel to aim the beam
- Off after 20 seconds in the dark, listed out to 16 feet
- 4.3 from 3,338 amazon.co.uk reviews
- Reviewers use it in wardrobes and on dark stairs
- £9.99 for a three-pack
Cons
- One buyer found the PIR unreliable
- Cheap plastic in the reviews
- Three AAA cells per bar, not included
- Not water resistant
Best for: You want a warm stick-on bar for a wardrobe or a stair, with a head you can angle, and you can spare three AAA cells per light.
Less suitable: You want the largest review sample in this set, or a bar whose housing reviews do not mention cheap plastic.

The RAWNICE 003 is a single rechargeable panel at £17.98 with a remote, a claimed 8,000 mAh pack that the listing says charges in about four hours, and a stated output up to 400 lumens. The maker claims 6–10 hours always on, or 30–60 days in sensor mode, and the modes include day, night and always on. From 196 amazon.co.uk reviews at 4.3 stars, people like the magnetic fit in an airing cupboard, the remote dimming and a dark staircase, and one buyer reported months of charge in a shed. Other reviews call the PIR temperamental and the battery poor after a few weeks. The page says water resistant and uses indoor and outdoor wording without an IP rating, so that line is not a bathroom or outdoor certificate. Detection distance is not stated.
Pros
- Up to 400 lumens claimed, the highest output figure in this set
- Remote for colour, brightness, modes and a timer
- Built-in pack listed at 8,000 mAh, about four hours to charge
- Reviewers use the magnet plate in an airing cupboard and on a stair
Cons
- PIR described as temperamental
- Battery life poor after a few weeks for one buyer, against a 30–60 day claim
- Water resistant has no IP rating
- No detection distance, and only 196 reviews
Best for: You want one bright rechargeable panel with a remote for a cupboard or a dark stair, and you can unclip it to charge.
Less suitable: You need a stated sensor range, an IP rating for outdoors, or a day-count that the reviews already support.

Common questions
What power source does the RAWNICE 003 use?
The listing states the supply as 8,000 mAh, USB, and the power type as usb rechargeable. The amazon.co.uk price in this comparison is about £17.98. That line is product data from the listing, not a measured runtime.
How far does the sensor reach?
The listing does not state a detection distance. There is no measured range in this comparison, so the table leaves that cell blank.
Is it suitable for a bathroom or wet area?
The listing says water resistant. That wording has no IP code, so it is not a bathroom rating.
Our view
The STAR-SPANGLED US-23A-WH2 is an 11 inch two-pack at £9.99, listed at up to 100 lumens from 10 LEDs, on within 16 feet in the dark and off after 20 seconds, on three AA cells that are not included. At 4.2 from 663 amazon.co.uk reviews it is the weakest star line in this set. Some buyers get enough light for a narrow cupboard and say it stays off in daylight, including one who mounted it above a door jamb. Others report a loose back cover so the batteries fall out, a unit that came apart while the cells were being fitted, and an inconsistent sensor. It is not water resistant. The length is the reason to look at it, and the housing is the reason the 7 inch bar from the same brand is the steadier choice.
Pros
- Up to 100 lumens stated, the highest single figure among the STAR-SPANGLED bars
- 11 inch length for a narrow cupboard or wardrobe
- Listed to stay off until it is dark, then off again after 20 seconds
- £9.99 for two bars
Cons
- Loose back cover so batteries fall out
- One unit came apart while the cells were being fitted
- Motion sensor described as inconsistent
- 4.2 from 663 reviews, the lowest star line in this set
Best for: You want a longer bar for a narrow cupboard and you will check the battery cover clicks shut before you stick it up.
Less suitable: You want a housing that stays closed, or the stronger review line of the 7 inch bar or the 3.1 inch puck.

Common questions
What power source does the STAR-SPANGLED US-23A-WH2 use?
The listing states the supply as 3× AA, not included, and the power type as replaceable cells. The amazon.co.uk price in this comparison is about £9.99. That line is product data from the listing, not a measured runtime.
How far does the sensor reach?
The listing states detection of 16 feet. That figure is the seller's claim, not a distance measured for this comparison.
Is it suitable for a bathroom or wet area?
The listing says the light is not water resistant. Keep it out of shower spray and other wet zones.

Motion sensor battery buying guide
These twelve lights are battery LED pucks, bars and one table lamp. The differences that change the purchase are shape, cells versus a USB pack, night-only behaviour, colour and whether a lumen figure exists. Prices on amazon.co.uk in this folder run from £8.49 to £19.99. A runtime headline only makes sense next to the seller's duty cycle. The notes below follow that order, and they do not turn any of these lights into a burglar alarm.
What is a motion sensor battery?
A motion sensor battery in this comparison is a battery LED light that switches on when a PIR sensor sees movement. The twelve amazon.co.uk listings are bars, stick-on pucks and one Auraglow table lamp. They light cupboards, stairs, halls and bedside tables. They are not intruder alarms, and they do not stand in for a handrail. Shape comes first. Stick-on pucks from AmmToo, the STAR-SPANGLED 3.1 inch pack, Detake, Oumida and Demlaies cover a hall or a cupboard door.
Best for
- Renters who need adhesive, a magnet plate or a freestanding lamp
- Night-time walkers who want warm light and a night-only mode
- Cupboard users who can charge a bar or swap a cell
Not ideal for
- Shower zones and any spot that needs an IP rating
- A new 230 V circuit, or a stair that needs a handrail
Mistakes to avoid
- 1
Trusting a day-count with no duty cycle
Headlines of 120 or 180 days assume a short burst, such as 10 uses a day for 20 seconds. Several review sets in this folder describe flat batteries much sooner. Quote the seller's assumption beside the number, or leave the number out.
- 2
Leaving day-and-night mode on
Daytime triggering is what empties cells. On the AmmToo pucks, one update puts empty AAA cells at about a month. If the light has a night-only mode, use that on a landing and check it still stays off when the room is bright.
- 3
Adding the two AmmToo review counts
The four-pack B08RXVJG49 at £15.09 and the eight-pack B0B28VC6ZN at £18.04 both show 4.5 from 6,959 reviews, with overlapping text. That is one sample, not 13,918 reviews. Buy the eight-pack only if you need eight pucks.
What to weigh up
Power and night-only mode
HighThe day-to-day cost is whether you buy cells or unclip a USB pack. Cells in this set are not in the box. Detake takes one AA. Auraglow and the AmmToo pucks take three AAA. The STAR-SPANGLED 3.1 inch puck and the 11 inch bar take three AA, and the 7 inch bar takes three AAA. A USB pack suits a light you can lift off a magnet. BLS lists 1,800 mAh on USB-C. RAWNICE lists 8,000 mAh. Oumida lists 600 mAh. Demlaies states a two-hour charge and a 180-day claim with no milliamp-hour figure.
Colour, output and mounting
HighWarm light is kinder on a landing at 2 a.m. Cool white is easier to accept over a worktop. Detake is about 4,000 K and states no lumens. BLS prints 7,000 K, with 250 lumens in a bullet and 180 in the technical table. STAR-SPANGLED states up to 80 lumens on the 7 inch bar and the 3.1 inch puck, and up to 100 on the 11 inch bar. Oumida states 50 lumens and three colour temperatures. RAWNICE states up to 400 lumens, with a remote.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
Night-time walkers
You want warm light that stays off until the landing is dark, and a sensor that sees you before the first step. The STAR-SPANGLED 7 inch bar lists 80 lumens, a 20-second off in the dark and a head you can angle.
Cupboard users
You want a bar or a brighter panel for a wardrobe or worktop, and a way to charge it or swap a cell. The BLS T61 is a USB-C pair with night auto and day-and-night auto. Cool 7,000 K light is the trade-off.
Common questions about motion sensor batteries
Which motion sensor battery is the top pick in 2026?
The Auraglow AG708 is the top pick among these twelve amazon.co.uk listings. At £9.99 it is a freestanding lamp that comes on within about 6 feet, holds a warm glow while movement continues, and has a permanent on/off mode. The line is 4.6 from 390 reviews, without a repeated failure in that sample. It needs three AAA cells, not included, and states no lumens. It is a night light, not a task lamp, and it is not water resistant.
How much does a motion sensor battery cost?
In the 19 October 2026 amazon.co.uk scrape, these twelve lights run from £8.49 to £19.99. Entry is £8.49 to £9.99, covering the STAR-SPANGLED packs, Oumida and Auraglow. Mid is £12.99 to £15.09. The top of this folder is £17.98 to £19.99, for RAWNICE, the AmmToo eight-pack, BLS and Demlaies. Cells are usually extra. A 120-day or 180-day headline is a seller duty cycle, not a promise your hall will match it.
What should I check before I buy a motion sensor battery?
Check four things in order. First, puck, bar or lamp. Second, AA or AAA cells you can swap, or a USB pack you can unclip to charge. Third, a night-only mode, because daylight triggering empties some AmmToo AAA cells in about a month in the reviews. Fourth, colour, and whether a lumen figure exists. Warm light suits a landing. Cool white suits a cupboard. Keep any of these lights out of shower spray.
Are these motion sensor batteries burglar alarms?
No. A motion sensor battery in this category is an LED light with a PIR sensor for cupboards, stairs, halls and bedside tables. If you want a detector that signals an alarm panel, start with the motion sensor comparison. Do not add the AmmToo four-pack and eight-pack reviews together: both show 4.5 from 6,959 with overlapping text. These lights also do not reduce the stair-fall figures published by RoSPA.
How long do motion sensor batteries last?
Only as long as the duty cycle the seller assumed, and the reviews often disagree. BLS claims up to 120 days at 10 uses a day for 20 seconds. Demlaies claims up to 180 days from a two-hour charge, with no milliamp-hour figure, and the reviews had not confirmed it. One Detake household changed an AA every three or four days. One AmmToo update puts empty cells at about a month when the puck triggers in daylight.
Can I use a motion sensor battery in a bathroom?
Not in shower spray. Most of these listings say the light is not water resistant. RAWNICE says water resistant and Oumida says moisture resistant, and neither gives an IP code such as IP44 or IP65. Some Auraglow buyers stand the lamp in a bathroom, but the listing still says it is not water resistant. A shower-zone light, or a new 230 V circuit, is work for a qualified person.
How should I recycle the cells?
Recycle portable batteries at a shop or a household waste centre, which is the GOV.UK route. If the cell is sealed inside the lamp, the whole lamp is electrical waste. Tape loose lithium terminals before you take them in. A dead-on-arrival unit, which one STAR-SPANGLED reviewer found as one dead light in three, is a Consumer Rights Act 2015 matter with the seller, not a reason to bin a lithium pack.
Our verdict
The Auraglow AG708 is the top pick if you want a warm lamp you can move, including an always-on mode, at £9.99. The STAR-SPANGLED 3.1 inch three-pack is the best value at £8.49, with the largest review sample and a stated 80 lumens, and with a dead-on-arrival complaint you should check on day one. Choose a USB bar such as the BLS T61 when you would rather charge than buy cells, and accept 7,000 K. Do not treat the AmmToo four-pack and eight-pack as two separate review samples.
