Pack of 50 Fixed Downlights & IP20 Rating This LED downlight comes in a pack of 50 , which is perfect for large-scale construction and renovation projects. Also, it has an IP20 rating , so you can use it for several indoor applications. Just remember that it s not water-resistant, so you cannot install it inside your bathroom or near water sources. Nonetheless, it s safe to install in your dining room, home office, laundry room, living room, hallways, pantry, bedroom, storage room, etc. Aside from that, this is a fixed downlight . After installing it, you cannot redirect the trajectory of the light beams. So, to ensure you are satisfied with the placements and avoid mistakes, plan and mark the positions of the lights before trimming! Hassle-Free to Install! Twist & Lock Mechanism The installation of this LED downlight is hassle-free since it's constructed with features that simplify the process! It s designed with a twist and lock mechanism (allowing fast bulb swaps) and push-fit terminal blocks for an effortless loop-in/out (no screws required). With this, you can wire each downlight in series instead of individually connecting them to the main power supply! It s also mains powered , so you don t need to purchase an individual driver or transformer to make it run. You only need to plot and mark the placement of the downlight, trim the cut-out hole, wire it straight to the mains circuit, and add the GU10 bulb you prefer. That s it! Fire Rated to 30, 60 and 90 Minutes; Ideal for Solid, Web, and I-Joist Ceilings This LED downlight is fire-rated to 30, 60 and 90 minutes of protection for solid joist ceilings and is suitable for web and I-joist ceilings for 30 minutes of protection . What does it denote? When mounting a downlight, you have to cut a hole into your ceiling. However, doing this compromises the natural fire barrier of your ceiling. Even if you eventually block the hole with the downlight, there are still tiny crevices where the fire can easily pass through. Only a fire-rated downlight like this one can repair your ceiling s fire protection because it s made with an intumescent pad that activates when exposed to a specific temperature. When initiated, this pad then blocks even the minute gaps, deterring the fire from entering! Insulation Coverable Some downlights are insulation-coverable . Yet, it's different for every brand or model. So, to make sure that your lights are undoubtedly insulation-coverable, check the product description or packaging. This LED downlight is insulation-coverable, so it's okay to place loft insulation loosely over its rear. However, you can only do this if you couple it with a GU10 LED lamp that has a maximum power of 7w. Several cheaper downlights cannot give you this, but this is a critical feature for your lights to have since the insulation will allow your home to diffuse heat quickly. This will help diminish the warmth in your space and lessen your electric bill! Works...
