User Review: Petzl MyoLite 3
Price Paid: $54.95
The halogen light is only bright for a few minutes, I am sure that's why the next gen has 4 batts. LEDs work forever. I only change the batts so they are fresh for a hike. Petzl says not to use lithium batts but I tried them and the halogen worked hours longer and was brighter than before.
This is also a pretty heavy light and has stood up to some major abuse.
