Need a high performance LED driver for OSTAR

[mhaskell]

Hi All, I am making a light using the current osram ostar and the newest Ostar (1100 lumens; 22.3V@1amp. 75lm/w@350ma).

I need a driver that will do 25v at 1amp and go as low as 20v at 350ma. I would like to power it with a 24v battery pack if possible, so a buck/boost converter, but that is not a requirement. Also I would like to be able to dim the light.

Does anything like this exist? I have not been able to find a driver to fit these parameters. If I have to run two drivers per LED I will, but I would rather avoid it.

Thanks.

Check out the shark at the sandwich shop, I think it's around that voltage. Sorry I don't have time to check it for you right now,

Unfortunatley the shark can only handle 22v output, and only 20v input.

Maxflex will go up to 24v

(20V max input)

Would you be interested in putting a second set of components togather while you are gathering? I have an aluminum watertight lighthead with a remote 24v NiMH pack that I would like to put a focused single ostar emmiter in for a high powered LED dive light.

Sure, I have bought several ostars and both spot and flood lenses. PM me if you want a set. I am just having trouble finding the right driver.

Thanks.
