I'm after a 35mm triple optic (to fit into a Hope HID shell). To be used as a helmet lamp. Can anyone suggest anything suitable.
I'm also looking for a suitable triple LED board, but I am now pretty much resigned to building my own- unless you know different. I'm definately limited to using a 14.8v Li-ion battery, so I'm looking for a suitable driver too.
All help appreciated, my head is getting cooked with this project TBH.
