The MicroLert offers unique features not before seen in industrial signaling devices. It is the first such light designed from the ground up to take full advantage of LED lighting technology. The MicroLert features an integral inverted cone design to provide full 360 degree coverage. The MicroLert lens is engineered for maximum light output and color clarity, and allows more of the LED light to be projected out than do conventional Fresnel lenses. The tough Lexan lens is spun welded to the base to completely seal out moisture. The MicroLert is UL listed and manufactured to NEMA 4X specifications.
