We offer a 5W and 10W LED bulbs (AC E26/27). They are manufactured using copper which is optimal for releasing heat. The heat sink is found inside the bulb with anti-shock protection. It weighs approximately 110g and the measurements are virtually the same as incandescent lamps. The design is mushroom shaped and the illumination angle is approximately 300 degrees wide. The temperature of the 5W glass, plastic housing, and LED chip are approximately 40, 50, and 70 degrees respectively. We are the Energy Star SSL member.
