This high-efficiency T5 HO fixture is equipped with 4 lamps that produce an amazing 20,000 lumens, while a standard 4 lamp T12 fluorescent fixture produces 11,800 lumens and a 200 watt incandescent standard household bulb only 3,900 lumens (varies by lamp type). ?Daylight? 6500? K lamp color makes this lighting very pleasing to the eye. The Tek PRO? 44 features a high color rendering index (CRI) of 84. The state-of-the-art highly reflective embossed aluminum reflector inserts are designed for superior light output, optimal reflectivity and uniform diffusion. The daisy-chain feature allows multiple fixtures to be plugged in together (not to exceed 12 amps).

Using fluorescent lamps cuts down the electricity consumption by up to 70% compared to HID and provides a better light output and higher quality light source. 120 Volt/216 Watts/1.8 Amps per fixture.
