How to use an LED work light
Updated: 2026-10-21
You have just unboxed a work light for a Sunday job, and the first evening usually goes wrong at the plug, the reel or the aim, not at the lumen number on the title. How to use an LED work light starts with the supply you actually have, then the lead, then where the beam points. The lamps in our [LED work light comparison](/hub/workshop/led-work-light) are the examples below, with amazon.co.uk prices from 19 October 2026. This page is from the Products Compared editorial team. We did not run the lamps in a lab. A qualifying purchase can earn a commission at no extra cost to you.

Charge it, or match the socket
Charge a USB lamp before you need it. SYLSTAR’s WL013 listing talks about three to nine hours depending on the mode. That is a claim, not a time we measured, and reviewers say the bright settings need regular charging. Dancingboar’s solar panel is not a plan: one reviewer left it in direct sun for two days and saw no charge.
A bare DeWalt DCL050 does not include a battery. Click on an 18 V XR pack you already own before you treat the body as a light. Whether you should have bought a battery or a mains flood is the rechargeable or mains LED work light page. On a mains flood, read the voltage line first. Linke prints 230 V AC. T-SUN’s specification line says 110 V, and a reviewer describes a moulded plug with a 13 A fuse. A domestic plug should show the BS 1363 mark. If those two disagree, stop and check.
Run the lead so you will not stand on the switch
The T-SUN’s inline switch sits inches from the plug. Once you feed the lamp from a reel, that switch is on the floor by the socket, where a boot can stand on it, or it is up at the wall where you cannot reach it from the bench. Route the lead so the switch stays where you can use it without kicking it, and so the cable does not cross the doorway. Bellanny’s bullet claims about 3 m of cord. Linke’s lead is about 1 m, so the socket has to be close or you add an extension.
Unwind a cable reel fully before you load it. Electrical Safety First and the London Fire Brigade both warn that a coiled drum can overheat. Do not daisy-chain reels. A 30 mA RCD belongs on outdoor and damp work. Press the test button before you rely on it.
Learn the modes, then aim past your eyes
Several of these lamps hide the brightness steps in the same button. On the T-SUN you cycle the inline switch. Give it a deliberate series of presses before you decide the lamp is stuck on full. SYLSTAR’s heads can run separately, which is how you drop from the claimed 3,000 lumens toward about 700. DeWalt dims with a press on the button. Use the lower mode when you are close to the work.
Put the lamp to the side of the bolt so your head does not throw a shadow across it. HSE’s note on site lighting makes the same point: a single source in the middle of the space hides the work in shadow. A magnet only helps if the panel is steel. Luceco’s clamp is the better answer on a frame or a lip under the car. Where to put the lamp in a home garage is the LED work light for a garage page.
Heat, a trip, and when to stop
A warm housing is common and is not, by itself, a lab result. One T-SUN reviewer measured about 68°C on the aluminium back. That is their measurement, not ours. Do not sit a hot flood on loft insulation or a cardboard box. If the plug or the sheath smells hot, switch off and stop.
If a 30 mA RCD trips, unplug the lamp and see whether the trip returns. Call a registered electrician for a new socket or a fixed light. Call a competent contractor if the job is a temporary site supply. Stop if you are about to use a 230 V flood on a 110 V site.
Common questions
Why is the switch next to the plug?
On the T-SUN the inline switch is inches from the plug, which is what UK reviews describe. The lamp end has no separate control in that account. You either walk back to the socket or you leave the switch where it can be stood on. Route the lead so that spot stays visible and out of the doorway.
Can I leave the cable reel coiled?
No, not while it is supplying the lamp. A wound reel can overheat because the cable cannot cool. Unwind it fully, and do not plug one reel into another. Linke’s 1 m lead is the case that tempts people to add a coiled drum in a hurry.
How do I charge a USB work light before the job?
Use the USB lead in the box on a USB-C supply that matches the lamp, and charge it while you still have daylight. Do not rely on Dancingboar’s solar panel. WL013’s UK plug is for charging the pack, not for running the heads off the mains as a flood. The three-to-nine-hour claim on that listing depends on the mode and was not timed here.
The housing is hot. Is that a fault?
A warm back is reported, including about 68°C on one T-SUN review, and that figure is not our measurement. Move the lamp off insulation and anything that can scorch. If the plug smells hot, the sheath is cut, or an RCD trips as soon as you switch on, stop and unplug it. That is a fault, not normal warmth.
When do I stop and call an electrician?
Stop when you need a new socket or a permanent light, when a lead is damaged, or when an RCD will not stay in with the lamp unplugged from everything else. A home garage flood on a sound existing socket is ordinary use. A temporary supply on a site is a contractor’s job, not a longer DIY lead.
