As my entry for Mayhem has been confirmed it's time to build some new lights...
Twin light set using XM-Ls and modified Regina reflectors. Front lens are MagLite AA lens (which are a snug push fit). Housing is 1" tube opened up to 7/8" on the lathe with 7/8" bar as a heat sink and a slice of 7/8" tube glued in to secure the lens.
Basic components:

Assembled:

Helmet mount is a bit of bent aluminium which fits snugly to my helmet
and has velcro on both sides. The helmet has a strip of velcro stuck to it:

Mounted:

I'm waiting for the driver to arrive, so no beamshots. It's a 2.8A driver so ~900lumens each with 75%, 25% and 2.5% modes. Battery life will be 4 hours on max from a li-ion pack.
