Original Press Release

Larson Electronics Releases a Manhole Mounted Explosion Proof LED Light Fixture with 100' Cord Reel for Group B Hazardous Locations

Press release date: August 22, 2014

Larson Electronics has announced the release of a Group B approved temporary manhole mount LED light fixture that provides operators with a powerful and highly convenient alternative to traditional string or tank lights.

An innovative 24” man-way support bracket combined with a compact design and LED technology make this lamp an excellent lighting solution for operators working within storage tanks, railcars, and other locations where entry is through a 24” manhole opening. The MMLP-1MLED-B-24OD-36P-20O-100HR from Larson Electronics is Class 1 Division 1, Group B approved for use in environments where hydrogen is always present. The copper free aluminum alloy body is powder coated for added durability and an attractive aesthetic appearance. A special heat dissipating design in conjunction with advanced LED technology helps this fixture achieve an excellent 60,000 hour rated lifespan with 80% lumen retention. This 16” diameter LED light is attached to a 24” supporting plate which allows the light fixture to hang inside the tank or railcar while the supporting plate rests on the lip of a man-way opening. This mounting system provides an extremely versatile lighting option for those working in confined spaces such as rail cars, storage tanks, ship tanks and the like where entry is through a 24” man-way opening. The light is suspended 36” from the lip to lower the light source into the tank.

This light is multi-voltage capable and can be operated with 100-277 volts AC without any need for a special ballast. The power receptacle on this tank light is constructed of non-sparking aluminum and finished with an epoxy powder coating while the body is constructed of triple coated malleable iron for durability and added corrosion resistance. The internal receptacle plug contacts are constructed of brass and designed to maintain constant pressure along their entire length for superior connectivity. The plug receptacle is deeply recessed to prevent accidental contacts and designed for twist lock plug insertion to provide secure connections. A neoprene seal fitted inside the connector receptacle seals against the plug when inserted to provide positive sealing against water ingress. A spring loaded receptacle door provides an automatic weather-tight seal when the plug is removed. In standard installations, threaded rigid pipe is brought to the outlet and the outlet is affixed to a mounting surface.

“This manhole mounted explosion proof LED fixture is for those applications where hydrogen is always present in the work area,” said Rob Bresnahan with Larsonelectronics.com. “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.”
