Research Project Summary Information

FLEX SSL Demonstration(27232)

Autronic Plastics, Inc.


Every year approximately 170,000 commercial buildings are constructed in the U.S., with 7% of these buildings built in New York State. Adequate lighting at construction sites is necessary for the safety and productivity of construction workers. Even though construction work is done during daytime hours, daylight often needs to be supplemented by temporary lighting due to the size or design of the building, the working hours, time of year and weather conditions. Commercially-available temporary lighting for construction often does not provide quality lighting that minimizes glare and reflection. OSHA regulations only require that construction sites be lighted to a minimum of 5-foot candles. For a typical 50,000 square-foot building under construction, an incandescent temporary-construction lighting system would have a connected load of 75 kW and a metal halide system would have a connected load of 26 kW for 24 hours a day. Metal halide lamps can only be used in a small percentage of construction sites because they require a high mounting height to obtain even illumination, and they also are fragile and difficult to store.

Project Description

The Contractor will demonstrate the FLEX SLS system for temporary construction at the site of the new Police Academy being constructed in Queens, NY. The FLEX SLS system, manufactured by Clear-Vu Lighting (a subsidiary of Autronic Plastics), is a novel low-voltage lighting system composed of light-emitting diode (LED) modules—each module producing approximately 2,100 lumens in a Type V spread-a 450W power supply with integrated time clock and dimmer; and a low-voltage (24VDC) bus line. To achieve the five-foot candle OSHA requirement, the LED modules are positioned at 17-inch centers from an 11 to 20 foot height. Fifteen independent LED modules are connected to the 270-foot low-voltage bus line, which in turn is connected to the 450V power supply. Rensselaer Polytechnic Institute's Lighting Research Center (LRC) will conduct an independent evaluation of the demonstration and the results will be published in a Design Evaluation of Lighting Technologies and Applications (DELTA) report and posted on the LRC website.


Gains include energy (kWh)and demand (kW) savings; lamp replacement and maintenance financial savings; and increased job-site safety and security associated with improved lighting at construction sites.
