Binary 2013 11x15x6"
A large lens from a photo enlarger magnifies the filament. It is removed for bulb replacement by unscrewing the round wood knob at the top.
The black face plate was carved from a 3/8" steel helium filling gauge for weather balloons. The wood is oil rubbed padouk, or redheart.
Light from the filament, passing through a triangular window cut in the bulb's parabolic housing, is reflected into the amber spherical lens by the mirror, as shown. This produces a miniature companion image of the bulb filament (right).
