OmniMax LED High Mast Light

Light the whole yard from one ring.

A high mast luminaire for ports, highways and yards, in a 500 or 750 W class. An eight-step dial behind the door sets the output on site, and the Type V optic turns 165° either way, so each head on a ring can take its own sector. Up to 106,500 lm at 5000K. IP65, 10 kV surge, −40 °F to 113 °F, 24/7.
