Is this 10Watt LED light a real product?

[picard]

Do 7W, 10W LED lights exist?
I found this 10Watt LED light on battery junction. I can't believe it can produce 10wat on 2 CR123A batteris.
Can somebody tell me if this product is real?

There are no 7W and 10W LEDs that exist that I know of. I don't think Luxeon produces a 7 or 10W LED.

7W & 10W refer to battery drain, not power to the LED.
Most 7W runs a Lux III at 1000 mA (4W) and waste 3W as heat across the dropping resistor.
The 10W uses a more robust K2 emitter, feeds a bit more power to the LED and wastes even more power through the dropping resistor.

Here are some more 10W lights

All this is old technology. The Cree/SSC/rebels are twice as bright for the same power input. I suggest you spend that little extra bit to get a Cree light. If you absolutely can not afford the price of say this you can get it cheaper [url="http://www.dealextreme.com/details.dx/sku.6177]here[/url]

A word of warning. MattK of Battery Junction is rather picky about what he carries. DX and Kai will list everything available including lots and lots of junk. And they don't always carry stock so shipping could be next day or 3 months from your order.

Wow 3W of wasted energy across a resistor is a lot.

You will probably get very short runtime.

Wow, look at the data - A bit more than 100 Lumen with 10W energy consumption. That is what I would call a bad lumen/watt rating of abount 10Lumen/Watt!! I wouldn´t even touch that thing!

Besides that THERE ARE 10,15, 20 50 Watt LEDs availible. But most of them would not go very well in a flashlight..

Ok . I won't buy the light. thanks for the tips guys.

the only real 10 watts light is from surefire...

and there is only 1 in the world...

PK has the light...
