The Sun System® 630 watt LEC® Boss Commercial Fixture combines cutting-edge Light Emitting Ceramic® (LEC®) brand technology with Sun System® 1 Etelligent™ controllability options (controller sold separately # 902245). State-of-the-art 95% reflective German aluminum interior with 95% reflective corner inserts offer unparalleled output, reflectivity and diffusion. Includes Philips highly efficient agriculturally engineered CDM-T 315 watt lamp. The lamp creates amazing full color light spectrum out of next-generation ceramic lamps. Higher amounts of beneficial UV and far red spectrums increase the lamp’s growth power to the plants. The 3100° K lamp is a very high 1.95 PPF per second light source. Available in 3100° K or 4200° K color temperature, high 92 CRI, 33,000 initial lumens (105Lm/W). The long life 20,000 hour lamp has an excellent continued performance, 90% lumen maintenance @ 8000 hours and a high, 85%, PPF maintenance @ 20,000 hours. Unique open rated lamp construction reduces radiant heat from the arc tube and is suitable for open fixture use. Ballast has a thermally optimized non-fan cooled aluminum housing that is ideal for commercial environments. Operates on 50/60 Hz low frequency, square wave, which makes this electronic ballast highly efficient and designed specifically to drive LEC® lamps at sustained peak performance. Internal ballast programming will protect unit in instance of open circuit, short circuit, over/under voltage or high temperature exposure. Features internal built-in circuit breaker. This fixture is dimmable which allows for operation of a lamp at 50%, 60%, 70%, 80%, 90% & 100%. The low-current, staggered ignition delay feature eliminates circuit inrush overload and protects lamp for increased lumen maintenance. Features compact commercial warehouse design.
