Description and Features
All dimensions
in inches.
Ø.128
Ø.232
These revolutionary new LED lamps emit
a true blue color (430 nm) for those design
engineers looking for that fourth status
color. Lamps are manufactured with state
of the art Silicon Carbide (SIC) technology.
LED lamps are available in both T-1 and
T-1 3/4 package sizes, in both diffused
and non-diffused lens types.
