The standard running temperature of a LED bulb is 40 to 70 degrees Celsius. Halogen and incandescent bulbs operate well over this with halogens reaching 200 degrees within only 2 minutes from activation! At these temperatures, a halogen light is not only a burn hazard if touched but also a fire hazard. See the links below for examples of houses damaged by fire due to halogen lighting.

Sustainable Lighting Solutions products are far less likely to cause a fire due to their much lower operating temperature. We also recommend where possible, to use the GU10 downlight bulbs instead of the MR16 downlight bulbs because they are not only more efficient to run, but they don’t require transformers. Transformers, although less likely to cause fire than halogens, have been linked to a number of household fires.

The heat generated from a standard halogen bulb increases your air-conditioning costs and can make it very uncomfortable to work around, see our stage lighting page for more information on how you can make a stage far more comfortable to perform on: Stage lighting.
