The Larson Electronics MMLP-1MLED 150 watt Temporary Manhole Mount Light Fixture provides operators with a convenient alternative to traditional string or tank lights. LED technology, an innovative 21” man-way support bracket and compact design makes this lamp an excellent lighting solution for operators working within storage tanks, railcars, and other locations where entry is through a 21” man-hole opening. This Class 1 Division 1&2 Class 2 Division 1&2 explosion proof light fixture provides 10,000 lumens of light while drawing only 150 watts. This 16 inch diameter light is attached to a 21 inch supporting plate which allows the light fixture to hang inside the tank or railcar while the supporting plate rests on the lip of the opening. A special heat dissipating design helps this fixture to achieve a 60,000 hour rated lifespan with 80% lumen retention. This light is multi-voltage capable and can be operated with 100-277 VAC without any need for a special ballast. The aluminum body and LED lamp gives this light added durability and resistance to vibration and impacts.
