The DLE4 Edge Lit 4 in. Round LED Downlight creates an attractive visual aesthetic with a low profile that's incredibly easy to install. The edge-lit technology uses a reflective light guide panel that disperses light through a diffused lens, making it a practical, economical and energy efficient solution with high performance. This high-performance downlight features 96 CRI, with an R9 value exceeding 50, making the DLE4 among the highest rated light fixtures in terms of light quality. Installation does not require a recessed housing, only a simple 4.25 in. in diameter cut-out in the ceiling using the provided template. The ultra-thin fixture depth (less than 1 in.) and off-board driver (included) allows for a more flexible installation and increased lifetime with superior heat management. The DLE4 features adjustable spring-loaded retention tabs for a secure fit, eliminating the need for a J-box or recessed housing. Adding light in tight spaces such as living rooms, hallways, bathrooms, basements, entryways, porches and utility closets just got easier. The DLE4 is Title 24 Compliant (except 5000K version), ENERGY STAR rated, Insulation Contact rated (IC-rated), Airtight, Damp-location rated and is protected by NICOR's 5-Year Limited Warranty. Color: White. Material: Aluminum.
