I realize this is an old thread....but...
Advanced and Eshine are the same company. Advanced is rebranded and sold for twice the price. They pretend to be different (wouldn't you?) and will even dog eshine. But there are several videos out there on YouTube showing the 2 side by side, and then being disassembled. Same exact parts inside. And, they have the same mailing address. In general, any led light made in China is garbage. Some may work for awhile just fine, but the majority of them are a waste of money. They all lie about output/specs. If you want a real led light. ...build one. Or plan to cough up alot of cash for a Bml Spyder or Illumitix. Area51.....made in China.
