I bought this set from Deesta over on the MTBR forums, got them home and ran them all night to test the battery life. 6 hours later I had to turn them off as it was 1AM nad I needed to get my head down. I've used them on numerous night rides since then aswell as a Mayhem and a Sleepless and they've been faultless.
The light itself was a prototype built by Deesta. Hand built lathed alloy 1 piece case with a grommet sealing in the electrics. a remote switch which has a velcro strap can attach to the bars or helmet vent and deals with the power switching. from the switch a cable runs to the battery. a simple male-female connector here is adds a safety element incase the cable catches on a branch or somesuch. It's also where the charger is plugged in. The electronics are provided by a Cutter triple Cree R2. The battery is one of Smudge's famous batterys and seems to do an extraordinary job of running for hours on end. Fantastic work for a 3600mAh unit.
I'd like £100 posted as PayPal gift or bank transfer.
Here's a beamshot from the 6 hour mark on my light test last year
And here's a few of Deesta's photos from when I bought the light.
