Does it seem like a non - e-switch driver could be swapped into it? Although the usb charging feature might be lost? It looks like a decent host to handle some heat within normal current limits and for shorter periods of time. Having crescendo or some kind of ramping firmware could be useful. I'm looking for a moderate thrower with some useful spill. Other than swapping the mcpcb, does anyone see this light as a host with other potential for mods? or just a good value as it stands? That depends on the intended end product, but I'm thinking at least a dedomed xm-l2 with 2.5-3ish output on high for maybe 90 seconds max if possible. I haven't modded too many headlamps, so that might be more current than necessary though. My goal is something like 100yards of visibility or more and a non-pencil beam. Does anyone think it could handle an xhp50 or xhp35 with the right driver and wattage, or is that pushing the limits for your every-day modder (without a lathe, tons of experience, and the ability to mold copper to your will)? This is BLF, but are you better off spending more if upping the output and throw is the end game? I mean, crazier things have been done before, and I applaud that:
