PRODUCT DESCRIPTION
The oval LED is widely used in variable message signs(VMS) and passenger-information signs.
The high intensity of oval-shaped LED with wide viewing angle ensure that its outdoor applications can be readable under the sunlight.
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.
