Overview

The NSi Industries 2000 Series Photocell (SKU: 2000) provides reliable, automated outdoor lighting control for various applications including flood lamps, patio lamps, and decorative lighting. This 120V unit features a conformal-coated cadmium sulfide (CdS) sensor, calibrated to mimic human eye spectral response for accurate light detection. It offers precise ON/OFF switching at 1-5 foot-candles (fc) for ON and 3-15 fc for OFF, with an adjustable slide cover for easy calibration without tools. A built-in two-minute delay prevents false switching from transient light sources like passing vehicles or lightning. The impact- and vandal-resistant Lexan housing, with a UV-screening translucent dome, ensures durability in extreme temperatures ranging from -40°F to +140°F. The 2000 Series photocell supports significant load capacities: up to 2000W for tungsten, 1800VA for ballast, and 600VA for LED lighting. In case of failure, the unit defaults to the ON position for safety. Installation is simplified with a 1/2" stem mount and three color-coded, 6" lead wires (#16AWG, 105°C rated). Backed by a 5-year warranty, it meets ANSI/UL773A standards.
