OSTAR ® - Lighting without Optics is a led lighting device from OSRAM, which has outstanding brightness and luminance due to pure surface emission and low Rth. The color temperature is 5600K, the color rendering index is 80, and the viewing angle is 120 degrees.
The LE W E2A is an OSTAR® lighting‑without‑optics LED that offers very high brightness and luminance thanks to ThinGaN® technology. It is lead‑free, RoHS compliant and intended for general, medical, and traffic‑sign lighting applications.
The datasheet lists key electrical and optical parameters, maximum ratings, brightness groups, and ordering codes. It also includes revision history, packing instructions, and safety notices for use in life‑support devices. This manual is written in German.
