This document describes the features and characteristics of LE CW E2B OSTAR® - Lighting with Optics (silicone) product. The product offers extremely high brightness and luminance due to pure surface emission and low thermal resistance. It has color coordinates of x = 0.42, y = 0.40 (warm white) and is available in various color temperatures. The product has a viewing angle of 130° and a light emitting surface of 2.1 mm x 2.1 mm. It utilizes ThinGaN technology and has a luminance of 12*106 cd/m² (4200 K) and an optical efficiency of 46 lm/W (350 mA, 4200 K). It can be mounted using screw holes and solder pads.
The LE CW E2B is a thin‑GaN surface‑mount LED offering high brightness and luminance thanks to pure surface emission and low series resistance. It is available in warm‑white colour temperatures from 2700 K to 4200 K, with a 130° viewing angle and a 2.1 mm × 2.1 mm emitting surface.
The datasheet provides detailed electrical ratings (forward voltage, reverse voltage, surge current), thermal characteristics, and ordering codes for different brightness and chromaticity groups. Packaging is in trays of 60 pieces, and the component is RoHS‑compliant and ESD‑protected up to 2 kV. This manual is written in German.
