I dont know it, and its kinda hard to say anthing about this light due to the lack of information, but i wouldn't buy a Luxeon flashlight when you can get a Cree or SSC based flashlight for the same or less money.
Or if you wanna buy a seperate light and charger (I'd suggest the Ultrafire WF-139), check the other offerings of Cree and Seoul led lights at kaidomain and dealextreme.
Agree! Also, check out the shipping charges they want: $14.99. That's how ebay purveyors make their "real" money. Check out Deal Extreme http://www.dealextreme.com/ or Kaidomain http://www.kaidomain.com/WEBUI/Default.aspx. These two sites, operating out of Hong Kong like most of the ebay folks have better merchandise and frequently shipping is included free for flashlights. Cree or Seoul leds--much better. Twice the efficiency, hence twice the light or runtime or combination. It's the latest wave of technology in leds.
hk: If you tell us what you want to use your light for, what your budget is, and any features that are important to you, then you are more likely to get good recommendations. By the way, I wouldn't get a no-name light from eBay, but that's just me.
