DESCRIPTION

Bright illumination and wide viewing angle are two outstanding
features of the 4 mm flat top lamps. The cylindrical shape and flat
emitting surface make these lamps particularly well suited for
applications requiring high light output in minimal space.

FEATURES

• Wide viewing angle

• Excellent for backlighting small areas

• Solid state reliability

• Choice of tinted clear or tinted diffused package
