"p7 et al - I dunno, the idea of dozens of AAA batteries kicking around in various states of [dis]charge seems like a right old faff and for me riding in the deserts round here leaves you a little vunerable..."
Don't think I've seen a P7 that runs on AAAs, it'd be a pretty awful idea really. Mostly they run off lipo cells, 18650s are the most common for the torches and self contained single packs for the bike lights.

let's face it, we live 55ish degrees north of the equator, it's too dark to ride after work for about 7 months of the year. A set of riding lights* will more than double the number of evening rides you can do in a year.
Riding in the dark means you can ride on footpaths without getting lynched**
and it's awesome fun!
even the expensive ones are a bargain; £300*** to get (more than) double the fun out of your bike.
Get something bright to go on the handlebars, and something less bright to go on your helmet.
going on quoted outputs, i'd suggest that 500lumens is enough for your main 'bar-light, and 100 lumens is enough for your helmet spot-light.
more is better, but you really don't need to go nuts, 1000 lumens doesn't look twice as much as 500lumens, cos your senses are logarythmic.
and really, please, don't make your own lights. it sounds like fun way of saving money, but you'll still be dicking around with heatsinks and silicone sealant next june.
(* as opposed to 'being seen' lights)
(** assuming you don't live in scotland)
(*** you don't need to spend this much)
