Overview:2W power Custom Made with 110V circuitry & 18, 000MCD emitters Multicolored LEDs slowly changes color to create a unique mood for the room Screws right typical 27-mm bulb sockets Lasts virtually forever. Never change bulbs again! Saves lots of utility bills -- uses only a few watts to operate Heat release design vastly enhanced over previous no name versions we used to carry, thus bulb life time can reach theoretical LED lifespan of 200, 000 hours (but expect at least 20, 000 hours) Also tested to work on 220V power but life span will be greatly reduced Specification: Weight Approx:45.7g Size Approx:4.9 x 4.9 x 4.5
