The flashlight/torch linked to on page 30 is only a Q3. Unless it's overdriven there is no way it will be that good in my mind. Shining against a wall is not the same as getting out and using it in the dark and seeing how it lights an area up.
He says the compares the peripheral light against a P7 for goodness sake. Sure if you widen it right up the immediate area may be flooded, but the distance light will suck badly.
Also, it WILL NOT be anywhere near as bright as an R2 that will cost about £3. I do like the ring on the light though, nice touch. I'm happier cutting up a cheap torch to mod. For the money, these 5w ebay lights are great though from what i've read.. just wish I actually had mine here lol.
BTW.. first ride into work today 10 miles straight off the bat eek! Not bad, haven't cycled for about 17 years!
Thanks for the photo's I'll take a good look at them and try to decide where to drill into the casing, and how to rig the battery holder to pass power straight through.
