Mounting directly into industry standard sockets, the units are designed to replace many popular subminiature and miniature incandescent lamps. Using advanced AlInGap and InGaN technology in a multi-LED design, they provide illumination and the ability to mix colours. In addition, they last much longer than incandescent lamps ? up to 100,000 hours ? draw 90% less power, resist shock and vibration and generate no heat. Featuring true non-polarized design, both lamps are available in 6, 12, 14 and 24 VDC; the T 1 3/4 wedge is also available in a 28 VDC version. Operating temperatures range from -30 degrees C to +85 degrees C (storage temperature: 40 degrees C to +100 degrees C).
