High impact polycarbonate body, filled with TecNiq's unbelievably tough urethane, makes this light nearly hammer proof. Mounts by drilling a 3/4 inch hole and pressing into a grommet. A single high-output, next-generation LED typically exceeds specifications by several times. TecNiq also provides this same light with white, green and blue LEDs in a clear lens. Useful for indicators, accent lighting and area lighting in tough environments. As always, TecNiq solutions utilize the best quality components, and a simplified design, to provide our customers with a top quality product at a fantastic price.
