Aim it so your body is not the shade
HSE site-lighting guidance says to use daylight first where you can, and not to leave a blade or a bit in shadow. The same guidance says not to change the colour of a safety sign, so move a cool flood that washes one out. Regulation 8 of the Workplace (Health, Safety and Welfare) Regulations 1992, and PUWER 1998 regulation 21, ask for suitable lighting where they apply. A retail lamp does not meet those duties on its own. Under a car, use a magnet on the wing. The bay is on the work light for a garage page.
The lead and the switch are one hazard
Run the cable along the wall, not across the walk and not under the car, where a wheel or a creeper will catch it. The Bellanny bullet, confirmed by a UK review, is a 3 m lead. That reaches a socket on the near wall of a small garage and does not reach a socket in the house. A split sheath or a cracked plug is a stop, not a tape repair. INDG236 sets no fixed PAT interval and asks you to look at the plug, the lead and the case.
Heat and flicker are reasons to stop
If you cannot rest a hand on the case, or you smell hot plastic, switch off and let it cool in the open. Do not cover the lamp to soften the beam. Flicker is a separate stop: a chuck can look slow or still, so unplug and use another light. Two of five wowspeed reviews describe arcing or a buzzing plug, so leave that lamp unplugged. An SOS flash is not BS 5266-1 emergency lighting. GOV.UK allows torches for trained staff only on small, simple escape routes.
The check that is actually asked of you
Read the plate against the socket before you switch on. UK mains are 230 V with a BS 1363 plug. The T-SUN specification says 110 V while reviews describe a UK plug. The Bellanny specification says 220 V. If they disagree, do not force a match with an adapter.
The IET describes 110 V centre-tapped-to-earth as site practice, not as a voltage you create at home. A site transformer is a competent-person job. Call a competent person for arcing, a damaged lead, a new circuit, designed emergency lighting, or a conductive confined space. If the lead is the hazard every time, see rechargeable or mains work light.
Common questions
Where should I stand the light?
Stand it beside the task or above it, so your body is not the shadow on the blade or the bit. That is the HSE site-lighting point, and it applies in a garage as well as on a site. A lamp on the floor in front of your feet lights the concrete and shades the cut. Keep the beam out of your eyes, and do not park it where it washes out a safety sign.
Why is the switch next to the plug?
On the T-SUN, several UK reviews say the inline switch sits a few centimetres from the plug, not on the head. The listing gives no cord length to set against that. You operate that lamp from the socket end. Keep the plug where you can reach it without crossing the lead, and do not rewire the switch to move it. Find it before you start, not after the beam is wrong.
Is a hot housing normal?
Lamps warm up, and one T-SUN review reports about 68°C on the back. That single figure is not a typical temperature for every model here, and we did not measure it. If you cannot rest a hand on the case, or you smell hot plastic, switch off and cool it in the open. Do not cover it, and do not leave it on a dust sheet or a coiled lead.
What if the lamp flickers when I use a drill?
Stop the drill and unplug the lamp. One Bellanny review reports flicker that strobes a power tool, which can make a spinning part look slower than it is. A stored T-SUN review notes PWM, so the same caution applies there. Do not keep cutting to see if it settles. If the plug buzzes or you see arcing, as two wowspeed reviews describe, leave it unplugged and call a competent person.
Do I have to PAT test it every year?
INDG236 sets no fixed yearly interval. You are asked to look at the plug, the lead and the case, and to match the equipment to the supply. Some site notes use illustrative intervals that differ for 110 V and 230 V equipment. Those are not a domestic timetable, and they are not a reason to ignore a split sheath. Damage, arcing, or a new circuit means you stop and call someone qualified.
When do I stop and call someone?
Stop if you see arcing, hear a buzzing plug, find a split sheath, or smell burning. Stop if the plate does not match the socket and the tempting fix is an adapter or a transformer you cannot specify. Stop in a conductive confined space, and stop if the room needs emergency lighting rather than a task lamp. A competent person owns those jobs. You own the aim, the lead route, and the decision to unplug.
