NICOR"™s all new T6C-Select LED Troffers feature the latest enhancements in LED technology to improve efficiency and value. Each troffer features two selectable switches to control color temperature (3500K, 4000K, 5000K) and brightness (Low, Medium, High). The ultra-slim flat panel measures just over 2.2-inches in depth (including the driver) making it lightweight and easy to handle. The backlit LED system produces a brilliant and natural radiance while reducing glare. This eliminates shadowing and uneven lighting often seen in cheaper models. The T6C-Select includes a pre-installed dual-voltage driver (120-277VAC) with full-range dimming (0-10V) capabilities. The precision-engineered polystyrene lens is sealed to keep out dust and debris. The T6C-Select is rated for direct contact with insulation (IC-Rated) and reports a tested lifespan of over 54,000 hours. It"™s available in 1x4, 2x2, and 2x4 configurations and is ready to install directly out-of-the-box. Optional accessory kits for surface mounting or drywall framing are sold separately. The T6C-Select is protected by NICOR"™s 5-Year Limited Warranty.
