5050 RGB LED 5054RGB-45 There are three Epistar 45mil Chip in inside, Red, Green and Blue. Big size's chip in normally 5050 RGB SMD LED definitely will throw off a lot a of heat. But with this High Power SMDT RGB 5050 LED, this won't be a problem because of the heat sink on the bottom of RGB LED. Common SMT 5050 RGB LED usually got power with 0.2W. But people's requirement for brightness is getting higher and higher and 0.2W RGB 5050 LED couldn't fill it, then 4W 5050 RGB LED emerge at a historic moment with the highest brightness and higher Power! Brightness of 4W 5050 SMD LED: Red: 45-55LM Voltage: 2.0-2.4V Wavelength: 620-625nm Green: 70-80LM Voltage: 3.0-3.2V Wavelength: 5…
