by Shane Henson — January 6, 2014—New York-based LaMar Lighting Company recently brought to market its DSLED product, a unique bi-level light-emitting diode (LED) luminaire controlled by two external infrared motion sensors.
According to the company, the DSLED luminaire is designed to provide safe, dependable illumination while conserving energy, and operates at 20 percent power while consuming as little as 5 watts in standby mode. DSLED offers sufficient illumination for stairwells, corridors, conference and utility rooms and other areas where maximum light levels are not required on a constant basis, notes LaMar.
Upon occupancy, the fixture illuminates to full capacity, consuming only 25 watts. The unit reportedly covers a 360-degree, 26-foot diameter range using two motion sensors, which can be adjusted in the field for optimum coverage, range and time delay using optional infrared (IR) remote control.
The 48-inch-long direct lighting fixture has a modern, clean aesthetic and emits uniform, glare-free light through a white polycarbonate diffuser. The luminaire replaces one F32T8 lamp, providing 1911 lumens, at about 5000 kilowatts with a color rendering index of 71. It uses 144 high-quality Nichia LEDs with a rated life of more than 60,000 hours. Individual DSLEDs can be surface-mounted to a wall or ceiling or suspended with chains or other devices, adds LaMar.
DSLED is DLC-qualified and UL-listed and comes with a five-year warranty. Units equipped with an emergency battery backup are UL-listed as emergency and power equipment per UL924, and provide more than 85 percent of full light output for at least 90 minutes, the company says.
