A new temporary manhole light fixture provides an alternative to traditional string or tank lights for workers in storage tanks, railcars and other confined spaces, the manufacturer says.

Larson Electronics' MMLP-1MLED-B-24OD-36P-20O-100HR Temporary Manhole Mount LED Light Fixture features a 100-foot cord reel.

The explosion-proof, temporary manhole mount LED light fixture is approved for environments where hydrogen is always present, the company says.

The Group B-approved, explosion-proof light is approved for use in environments where hydrogen is always present, the company says. The 24-inch support bracket rests on the lip of a manhole opening and allows the 16-inch-diameter light fixture to hang inside the confined space.

60,000-Hour Lifespan

The body of the fixture is made from powder-coated, copper-free aluminum alloy; the heat-dissipating design helps it reach a 60,000-hour rated lifespan with 80 percent lumen retention, according to Larson.

The power receptacle is made of non-sparking aluminum and finished with an epoxy powder coating; the body is constructed of triple-coated malleable iron "for durability and added corrosion resistance," the company says.

"The explosion-proof receptacle mounted on the light assembly allows for daisy-chain connections, providing operators the ability to power lights and equipment within the hazardous location without requiring additional power sources or extension cords," says Larson spokesman Rob Bresnahan.
