Regarding the tesco torches. I heard of one user attaching a maplin battery pack to his bike which takes about 10 big batteries. On this the torches last for about 4 hours. I've thought about giving this a go but it seems like quite a lot of effort. He even sawed the torches in half.
Would love to see someone write a little guide.

Come on then! Put a review up! I'm thinking about these instead of my current Fenix. Have you got any beam shots?

Looks like an awesome torch for the money. Cheaper in bulk too but not by much.
hi,
i have 2 pairs of these;
http://www.amazon.co.uk/Kingavon-BB-RT314-Touch-Torch-Battery/dp/B0012UPH00
mounted under the handlebars with re-purposed reflector mounts. If you mount them on the brackets correctly you can also manually 'dip' them for use in traffic, although i may add some shades to direct the light downwards more effectively.
don't know about output etc, but all 4 seem to work well enough on dark country roads/ wooded cycle paths. (so far, anyway..)
(cost of 2.99 each in TKMaxxxxxxxx, reflector brackets free..)

1 2500mAh AA battery contains 3 watt-hours (1.2V x 1A x 2.5h), 4 contain 12 watt-hours. If the torch actually ran at 6W, it would last 2 hours. If it's lasting 20h, the average power consumption would be 0.6W at best.lazyfatgit said:
I'd guess that there's no regulation, and it starts off reasonably bright and gets dimmer fairly soon.

I doubt very much that's as bright as it claims to be, the battery would be knackered very quickly otherwise.Tony B said:

The P7 lights use 18650 batteries 3.7v, then the run time is about an hour.

Which is similar capacity to 2 x CR123A's which mine use which lasts about an hour @ 300 lumens.Tony B said:

The 900 lumens is the figure from SSC for the bare P7 LED maximum output, not a measured output from the torch.smeg said:
It's fairly common to quote emitter maximum rather than actual output as measuring actual isn't simple. It's easy to spot who's doing it even when they confess by saying "manufacturer rating" or such - anyone claiming 900 out of a P7 or MC-E, or 250 out of a P5 or XR-E.
By the time you allow for driver circuit losses, reflector losses, reduced emitter efficiency due to getting hot etc, even Lupine only get 700 lumen out of the front of their P7 light (Tesla). A DX cheapo isn't going to be as good as that.
I have to say that looks pretty damn impressive. How long will it run on that output though?
EDIT: Looking at the link you posted previously it suggests 30-50 minutes. 30 minutes! I'd need to stop and change batteries about 3 times on my regular nightime training route. Batteries can't possibly be that cheap.

They're rechargeable though and cheap off ebay (from Hong Kongkyuss said:
) it will also mean having to charge 3 of them if you needed to use that many in one go, so you'd might need more than one charger if charging one at a time because it will likely take too long. I bought a new charger for my CR123A's because the other one takes too long!
