Turbo LEDs from Bulbrite feature heat sink technology that eliminates the need for large aluminum heat sinks or clunky housings. Their cooling system has pure anodized 0.0236"-thick aluminum fins that are riveted to the body. The luminaires also are engineered with a low junction temperature of 149 F for optimal thermal conductivity to increase LED life to 25,000 hours, and, with an IP 65 rating, they are completely protected against dust and low-pressure water from all directions. Turbo LEDs are available in several sizes and styles, including MR16 12V; MR16 GU10 120V; PAR20; PAR30; and PAR38. They contain no mercury or lead. bulbrite.com
