With a baffle trim design that helps reduce the light glare, the 5-6 inch dimmable LED downlights of 15W available in 3000K, 4000K, and 5000K color temperatures help you have a beam angle adjustment (the beam angle being 100-degree) a unique feature that allows for light to be distributed in areas where it is required the most. A CRI of 90+ means excellent color rendering by this downlight when the objects and surfaces appear as natural as they would in natural light. These 15W dimmable LED downlights can conveniently replace 55W of dimmable halogen light. On average, the dimmable LED Downlight cuts down your utility bill by almost 88% and that is undeniably a significant amount of energy savings. This downlight beats the conventional halogen lights or incandescent light in terms of energy efficiency. Further, the 50,000 hours of lifespan for this downlight means low or no maintenance and replacement costs in extreme contrast to halogen downlights which last for a maximum of 1000-2000 hours. And, imagine then, how many times they would need to be replaced within 2-3 months of their lifespan. These 5/6 inch recessed ceiling light fixtures can be fixed both in 5 inches and 6 inches of ceiling space respectively.
