Hazardous-environment lighting – LED pendant light fittings

Cooper Crouse-Hinds has launched a new range of high-power LED pendant light fittings that are said to be suitable for use in Zone 1 and 2 hazardous gas environments and Zone 21 and 22 hazardous dust environments.

The new LPL LED pendant light fitting incorporates a high-power (10-30W) white COB (chip on board) LED array, which, according to the company, provides longer life and higher efficiency. It adds that the LPL LED (60-150W power rating) is ideal for replacing 70-250W metal halide (MH) lamps. The LPL LED is said to be Exd-protected (IP66), with a copper-free aluminium housing and a heat and impact-resistant glass bowl.

Permissible ambient temperature for the standard 60W/85W/100W LPL LED (6000K cool white) is from -35˚C to +50˚C (T6 rating). For the 125W and 150W versions, the range is -35˚C to +40˚C. Under appropriate ambient temperatures, says Cooper Crouse-Hinds, the LPL LED provides more than 50,000 hours’ expected operating life.

The company says the LPL LED is suitable for a wide range of hazardous areas, including applications in heavy industrial, chemical, petrochemical, oil and gas, pharmaceuticals, shipyards, dockyards, power generation, paper mills and wastewater treatment.
