Standard high beam bulb is 5.2V 0.5A. But you may put anything in up to some 4W. At least I had such a bulb in it with no problems at all (and a battery with 4 A NiCd cells (1.5Ah, pretty old))
I received information from a guy who's worked a lot with Petzl. He believes the 2.6W in Duo has 46 lumens output, while the halogen bulb in the Megabelt and Zoom has 33 lumens.
46/2,6 = 17,8W/Lm
This sounds a bit too high, doesn't it?
I'm wondering if I would get more halogen light in my Petzl Duo 4C headlamp without melting anything. Reduced run-time and bulb life is not so important for my application, which is biking.
Feedback, anybody?
P.S. WriteRight applied to the lens seems to smooth out the lousy rings a little in both modes.
