The Monsoon™ Series:  MON4  (Click here for Product Options)

The MON4™ is designed for cold applications (not recommended for use above 32F/0C due to lumen falloff) and has even ignited as low as -45F (although starting and operation is only warranted down to a mere -20F/-30C!). It’s been used successfully in cold food processing, cold storage freezers, walk-in coolers, and other cold environments - it's rated IP67, will withstand 1500PSI hose-down, and is NSF food-rated. It provides 10% uplight, with mechanical lamp protection from it’s nearly indestructible polycarbonate lens (4'-0" model only). The MON4™ can be ordered in 2’-0” or 4’-0” lengths.


One-piece compression-molded unsaturated polyester/fiberglass housing (6 ¾” x 4” profile) with (8) three-piece polycarbonate latches. Seamless continuously bonded poured-in-place low-memory gasketing (resilient even in cold environments). The unitized Ballast/reflector tray attaches to the fixture body with pinch-release clips and suspends from the housing during servicing. 1/2" conduit entry hole in each end of housing with weathertight plug. IP67 & NSF Food rated Housing.


HF electronic programmed start multi-volt ballast, mounted on stand-off ballast heatsink for long ballast life. Seismic make-and-break captive rotor sockets. UL/CUL listed. Lamps are 85 CRI with .95 lumen maintenance over life, and are rated at 40,000 hours life at 12 hours per start. UL/CUL Wet Location Listed.


High reflectance broad distribution white reflector pan/gear tray. Impact-modified UV stabilized polycarbonate (4'-0" model only) or optional high-DR acrylic lens for chemically sensitive installations; lenses are  linear-ribbed with smooth exterior face for ease of cleaning. Nominal 10% uplight component.


The MON4™ is provided with a pair of Quick-clip™ snap-on full-hard stainless steel mounting clips that will accept #12 S-hook & chain or 1/4" threaded rod, as well as allow surface mounting without penetrating the fixture body – watertight integrity of the housing is thus maintained. Quick-clips™ install anywhere along the fixture body, and positively lock without tools; they have a withstand rating in excess of 50X the MON4™ weight. Flexible mounting!
