I don't know.... one of the biggest drawbacks to cool lights is size and price... there are some other small lights out there, but not this small, this bright... when you can stick it in your pocket or on a belt loop, that opens up the market to emergency personel who will all want one for themselves, as well as hikers, sportsmen and even the common mechanic...small enough to toss in a tool box with ease..... small is good.....
some of us are willing to carry a cannon around to get the lumens, but most will not.
2 hrs runtime?.. not bad for a little guy.
I just see allot of work and expense and beauty... I know it would be totally marketable.... as to whether it would be profitable or not... that I don't know.
