I'm assuming this is for "tactical" use?
Yeah, Goldserve could whip you up a board that has only a strobe. The only problem is that we're talking about a modded light, not really something you can simply buy. You could, for example, buy a Jil TWOJ, a CAB extension, kroll switch, and a seperate U-bin LED (brighter), have him program a strobe FLuPIC board (it'd drop right in to the Jil), and power it with a 14500 (AA size) 3.7V lithium ion. Since it's a strobe, and not on all the time, it could probably handle 1200mA without frying. The kroll works momentarily with a light press, or clicks on for full-on use.
There's lots of options like this, for example a lot of people mod a Nuwai Q3 with a FLuPIC.
