Request for U2/L5 output comparison with Li-Ion

JanCPF · Dec 13, 2004

Could those of you who own both lights and have a Li-Ion cell, please compare the two lights to see if they have similar brightness (U2 on level 6 of course) or if one of them is brighter. I know that the lux lottery is in work here, but lets get some statistics.
Thanks.

EDIT: Just realized that I should have made this a poll, but I don't think I can add it now.

I compared one U2 to one L5 with Pila 168S and 123s.

I couldn't tell much difference using the ceiling bounce test. The U2 seems slightly brighter, but not enough to be sure.

I couldn't tell any difference between Pilas and 123s.

This test need to be done by someone with a light meter.

Hoghead,
Thanks, that is a very valuable test anyhow.

Anyone else got both lights?

The main problem here might be the Luxeon Lottery just as with the L2 vs. L4 thing ... where the L2 is driven harder, but the Luxeon lottery plays a big part, so you can actually end up having a brighter L4 ...
