Description:
CAO MediaVista
TM
high brightness LED lamps are specially
designed for outdoor signal and sign applications. Its precise
optical design produces a high bright light source and well
defined spatial radiation patterns. The water clear lens was
made with an advanced optical grade epoxy to produce
superior high temperature and high moisture resistant
performance in outdoor environments. It also contains UV
inhibitors to reduce the effects of long term exposure to
direct sunlight.
These LED lamps are water clear and use a standard T 1¾
(5 mm) round package. The chips of these LEDs are applied
to the most up-to-date material technology to produce the
most efficient light output and highest junction temperature
limit, which enable it to operate under bright sunlight and
other high temperature environment.
