LEW E3A OSTAR® is a lighting fixture with extremely high brightness and luminance due to pure surface emission and low thermal resistance. The color coordinates are x = 0.33, y = 0.33 (white), with a typical color temperature of 5600 K and a color reproduction index of 80. The viewing angle is Lambertian Emitter (120°) and the light emitting surface measures 2.1 mm x 3.2 mm. It utilizes ThInGaN® technology and has a luminance of 16*10^6 cd/m². The maximum optical efficiency is 38 lm/W at 350 mA. The fixture can be mounted using screw holes and solder pads for wire attachment. It has an ESD-withstand voltage of up to 2 kV (JESD22-A114-B). Each box contains 60 pieces. It is suitable for general lighting, medical equipment, microscope lighting, traffic signals, and high-quality flashlights.
