Heat has been an unfortunate by-product of many modern lamps. Halogen and dichroic reflector lamps produce a lot of it and must be placed at a suitable distance from their subject. Dichroics throw the heat back through the glass and shouldn’t be fitted in ceilings without fireproof covers. These small hoods prevent the heat from being transferred to the structure and charring it. They also act to ‘repair’ the hole in the fire-resistant ceiling. In the US, uplighters with halogen lamps in them gave rise to so many house fires that it soon became a requirement for manufacturers to fit protectors over them. As plug-in floorstand lights, they might house 300 watt halogens that get a little hot. LED’s are the first lamps to run cold, and as such, they don’t represent a fire risk in themselves, but the hole you cut into the ceiling to fit a recessed GU10 can. To overcome this problem, intumescent type casings should be used to house the lamps.
