ABSTRACT:
This invention pertains to a flashlight body. Either the main body or at least one closure cap has a luminescent outer surface. The outer surface comprehends a luminescent colorant composition in the base material. At least 50% by weight, up to 100% by weight, of the colorant composition in the base material is luminescent. No more than 50% by weight, of the colorant composition comprises reflective colorant material. Thus, the flashlight body emits, in the visible spectrum, light radiation derived in part from the reflective colorant material and in part from the luminescent colorant material. Light emitted from the luminescent colorant adds to the intensity of the light reflected by the reflective colorant to provide total emitted light intensity, from the flashlight body, greater than the light intensity from a corresponding amount of the reflective colorant alone, and characteristic fluorescent glow.
