Cree® Screen Master® 4-mm Oval LED
C4SMG-RJS/GJS/BJS
Data Sheet
The oval LED is specifically designed for variable-message signs and passenger-
information signs. The oval-shaped radiation pattern and high luminous intensity
ensure that these devices are excellent for wide-field-of-view outdoor applications
where a wide viewing angle and readability in sunlight are essential.
These lamps are made with an advanced optical-grade epoxy that offers superior
high-temperature and high-moisture-resistance performance in outdoor signal
and sign applications. The encapsulation resin contains anti-UV material in order
to reduce the effects of long-term exposure to direct sunlight.
