Abstract
Disclosed is a method for applying a yellow incandescent bugfoiler pigment coating comprising a fine-ground blend of praseodymium doped zirconium silicate and silica. This cadmium-free blend is preferably applied electrostatically in three coats to the interior of a bulb to diffuse the light and block the emitted UV wavelengths. The color of the blend will intensify with increasing heat and return to it's initial yellow color upon cooling.
