Since incandescent bulbs generate light by heating a filament, they also heat the lenses they illuminate. This causes discoloration and eventual melting of the control panel lenses. PowerLine® LED lamps generate much less heat than the incandescent bulbs they replace. Furthermore, heat is dissipated through the base of the LED lamp, keeping the lens cooler.
With the extended use of incandescent bulbs, lens melting and discoloration is very common. We offer replacement lenses for many industry-standard sockets. Please refer to page 10.
