Why don’t Lightwave LED torches have a protective lens?
A. Torches use a polycarbonate lens to protect the lamp but Lightwave claims these can rob 10% to 20% of available light and if the are scratched or yellow over time, even more light will be lost. LED’s , by design, have their own built-in solid epoxy lens which is incredibly tough and even if a chip was broken off, they would continue giving light. Lightwave torches also have a protective edge (they call it a Bumper Head) around the LED’s. This absorbs the abuse and provides additional protection for the tough LED’s.
