I dont trust them, I have had too many break bulb filiments when dropped.
The author seems to think you need 50 lumens *all the time*, yet I find that laughable
Even then, I was scrared to death of dropping it.
well, if you call this workinghmmm from your sigline, I assume you work for Petzl?
read most of it and looked at all the pictures. Hey, was that you with the king of delicate incans, the gas lantern?You will probably get a kick out of this post I did. its a writeup about my last big caving trip.

I am still waiting for an LED handlamp with the formfactor and throw of my UK4AA with 4-watt incandescent bulb. My headlamps (Petzl DUO) have been converted to LED (Petzl 8-LED modules) and my backup handlamps are also LEDs but I haven't found an LED lamp to replace the UK4AA/4-watt incandescent.I think alot of what that articale was also saying, is that they werent getting the shear output they wanted.
Well that is all changing now, there are plenty of led lights totally killing incans their size.
Yeah, he should write a companion article showing why it is unsafe to wear gloves when rappelling.My guess is the article was written mostly out of curmugeonly contrariness...

Try a Space Needle II (for throw) and you'll never reach for an incan again
