Hi
Apparently http://www.peakledsolutions.com/ were the makers of the parts for Arc flashlights.
I got this info from outdoorsupplies.com - http://66.147.225.206/ who are the european suppliers. I know they also deal within the US. Give them a try (email first) if you want.
On the same subject, has anyone dealt with Peak Led solutions before or tested thier products?
Cheers

EDIT
"Fools rush in..." A quick search of this forum for "Peak Led" (sans quote) resulted in hits from Paulr and Groo. I suggest you read thier posts,,
