The larger 3 watt RGB LEDs are very bright and colorful, but if you don't get the power just right - POOF! Now your RGB is R(nothin')B. The Star Controller tames this LED so you can power it up with 5 to 12V and use any regular 5V signal to control each channel.
Want some 12V LED lighting for your home or camper? The light emitted from this string closely resembles cool white fluorescent lighting and is a sharp and more focused compared to others of it's kind. Fair warning: probably not a good idea to stare directly into the light!
