My £7 incl p&p CREE (P4, I think - not even a fancier later version) is amazing as a 1xAA helmet light. Nice positive forward clicky, about 90 minutes runtime (I only switch it on for fast descents or when I'm caning it up the front of the bunch on the flat), really good throw (quite a focused beam, but with a functional amount of spill). Single mode.
Did my usual inner tube condom for it, and use velcro (old Zefal pump straps) to attach to the lid, and added a bit of silicone grease to the threads/o-rings. 1 spare battery in pocket (another Vapextech 2900mAh) which might actually get used on the upcoming hilly overnighter.

It's a Romisen RC-G2 from Dealextreme, BTW.
