Kevinm, Glad to hear that you are considering offering a product like this to the community.
Please start your own thread for the discussion of your light.
I will be watching closely. It looks interesting
Personally, I may never produce this housing.
Several factors led me to believe that it is just not going to work great and be a lightweight headstrap type of product at the same time.
If I did ever produce something, it would include heavy wiring, and extra heatsinking to handle todays high output drop-ins.
It all adds up to a heavier, larger product that would likely only work well in a helmet mount.
Thanks for the interest guys.
