The Model 121SLED is a compact, rotating warning light that operates on 120VAC and comes in five colors. It features a parabolic reflector that rotates around a 360-degree LED, delivering 60 revolutions per minute in all directions. The zinc die-cast alloy base supports surface mounting or ½-inch NPT pipe mounting. Optional brackets make it easy to install on walls or in corners. The twist-and-lock lens provides simple access for inspecting or replacing the lamp.

With a Type 4X, IP66 rating, the 121SLED ensures a water- and dust-tight seal. It also meets IP69K standards to endure high temperatures and pressure washdowns. This light is perfect for high-ambient and harsh environments where visibility is crucial, including emergency evacuation, hazardous area markings, overhead cranes, irrigation systems, and conveyor and machine start-ups.
