I thought that P7 LED's only went up to 200-300 Lumens. Have I got that wrong, or is this ad. bullsxxt?

Seems worth a punt at £50 even at 200 lumens, but maybe not.

What do you think?

Don't think that's a 1200 more like 900 think it's the one dealextrem sell but the newer ones have a sealed battery go look.

A p7 led is 900 lumen theoretical max output unless they have improved them

actual out put will be around 2/3 or 3/4 of this allowing for losses in the optics and less than fantastic electronics and heatsinking

great light and worth getting (got a couple - one on bars and one on helmet) but they are not 1200 lumen. They usually state 900, but that is still optomistic.

A German forum group have measured the lumens of a bastid in an integrating sphere and it measured
550 lumens.out the front

it is about time light making firms quoted the lumen count out the front of their lights not the max the led may be capable of.

sounds about right trout

Nightrider and someone else ( can't remeber who) quotes real outputs. Nightriders P7 led is sold as 600 lumen IIRC
