L1 works for me - Pelican 1930 L1 LED Pocket Flashlight

I purchased the L1 primarily for hunting & fishing in darkness, with green filter installed to save night vison & not attract bugs. I arrach the L1 to the side of my cat brim with small alligator clip, plenty of light for walking & tasks in the dark.
Pros: simple, color filters included
Cons: would prefer AA or AAA over button type batteries
