Fire-Rated to 90 Minutes of Protection & Suitable for Solid Joists and I-Joists This LED downlight is fire-rated to 90 minutes of protection. This means the hole that you trim to mount your downlight is resealed, and your ceiling is reinforced to prolong the time when the fire will spread (in this case, for 90 minutes). Only fire-rated downlights are capable of doing so because they're designed with an intumescent pad that activates when exposed to a particular temperature. When triggered, this pad expands, blocking even the tiniest entry points where fire may slip through. In addition, this LED downlight is suitable for solid joists and I-joists , which not many light fixtures offer. So, choose this LED downlight to guarantee that your home is fully fire-ready! Insulation Coverable (Maximum 7w GU10 LED Lamp) Before installing and using any lighting fixtures, go through its product description and technical specifications first.

This bulb can produce 400 lumens maximum brightness with a broad 110-degree beam angle while only consuming 4.5w of power! It's super energy-efficient, so even if you use your lights for extended hours, it will not inflate your electricity bill too much. Besides that, the GU10 LED bulb that comes with this LED downlight has a cool white LED colour . Unlike warm white light with a yellowish tint that resembles an old incandescent bulb and natural white with no hints of blue or yellow (like a cloudless sunny day), cool white has a crisp bluish tone that is typically used for task lighting!
