As per usual Petzl have gone for the easy manufacturing option and settled for a moulded plastic case, which means that with no heat sink / dissipation the 6x 3W L.E.D. s have to be throttled back, even on the highest setting. It's not a bad light, but certainly not the best; nor is it good value for money against the Hope range. Even the Hope Vision Two bangs out around something like 480 lumens from 2x 3.5W L.E.D.'s for around £180, albeit a rather narrow beam.
The real cognoscenti appear to go for a Hope lamp on a Petzl head-harness.
