The Evofire Fire Rated Downlight is a safe and attractive fitting for a GU10 LED lamp (not included). The patented "canless" design of the Evofire does not conceal your lamp in a large metal canister, which can trap some of the heat it generates, lowering lamp lifetime and performance. Lamps installed in an Evofire run at up to 10 degrees C cooler than a typical can-style fire rated downlight from leading LED brands - this can extend the lifetime of your lamps.
