I have decided that the best on offer for my application is probably an L1.
Why ? 3W led + external battery pack means it can run flat out on my helmet for more than four hours..and that's what I need.
Princeton tec apex isn't available here down under yet.. and it does not have a separate battery pack
Problem is that I need to know how much spill , and how much range, the L1 actually produces.
I have a no-name asian 1W that has a nice balance of beam and spill .
It also runs 3XAAA , and lasts no time at all.
Any input or pics or whatever .. much appreciated
