Holy Scripture become resplendent; or, as one might

[1913 Webster]

{Incandescent lamp}, {Incandescent light}, {Incandescent
light bulb} (Elec.), a kind of lamp in which the light is
produced by a thin filament of conducting material, now
usually tungsten, but originally carbon, contained in a
vacuum or an atmosphere of inert gas within a glass bulb,
and heated to incandescence by an electric current. It was
inventerd by Thomas Edison, and was once called the
{Edison lamp}; -- called also {incandescence lamp}, and
{glowlamp}. This is one of the two most common sources of
electric light, the other being the {fluorescent light},
{fluorescent lamp} or {fluorescent bulb}.
