Grote Industries says its new LED ‘WhiteLight’ recessed-mount dome lamp is an "intelligent alternative" to fluorescent lamps, particularly for refrigerated environments with subzero temperatures.
 
Though fluorescent lamps can operate at temperatures as low as zero degrees F, today’s refrigerated environments can challenge lamps to provide illumination in temperatures as low as -40 F. Grote says its new model 61291 uses a built-in thermal protection device and operates at temperatures ranging from 122 to -48F.

The new lamp is constructed of a robust, one-piece, powder-coated aluminum housing with a removable polycarbonate lens. It has a 50,000-hour service rating.

The lamp’s six diodes generate light output comparable to that of fluorescent lamps, but draw only about 63% of the amperage, says Grote.
