Our P7s arrived yesterday, they're torches by the way, and Clive and I got them fixed on the bikes pronto and went out to trial them last night. They're rated at 900 lumens and whether they actually are that, they're pretty damned bright. The P7 is the black torch in the picture by the way, and though it might look like I have a surfeit of lights on the front of my bike, they all serve a particular purpose!! Anyway the P7 itself performed admirably both on full power (very strong) and reduced power (enough to see and be seen). A fine addition to my handlebar torch collection!!!!!!
