Bought this headlamp along with two other less expensive headlamps to compare them. The Brunton L3 (3 watt) and the BD Icon (3 watt / 100 lumen) were comparable to each other. But the Petzl Ultra WAY outshined those two. What a solid headlamp too. I couldn't help but think that this is THE headlamp for search and rescue types who want LOTS of light! Simply amazing.
The other thing I love about the Petzl Ultra is the Lithium-ion rechargeable battery. It has to be the best headlamp battery anywhere. If this headlamp wasn't so dang expensive it would get 5 stars from me fer sure.
