·PRODUCT DESCRITION
·The 4-mm oval LEDs is widely used in Full-Color Video Screens ,passenger-information signs and digital billboards. The high intensity of oval-shaped LED with wide viewing angle ensure that its outdoor applications can be readable under the sunlight.
·The 4-mm oval LED 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.
