Sorry about the typical newbie type question but I could do with some help with this one. After reading the excellent reviews on here I got the MRV to double up as a reserve bike light. With its excellent light output it is really too good to play second fiddle and with more run time would make an excellent permanent light. I've got a few packs of NiMh batteries that put out around 7v and which would give potentially excellent run times. Unfortunately, in my ignorance I'm not sure whether this is feasible. In fact, I'm not at all sure which categories of batteries can be mated to which lights. Can anybody point me in the direction of any information to help with any of this? Thanks.

Get rid of the battery tube - check if it possible to screw tail cap into the head, drill tail cup and put there cable to you battery pack... (connect cables with connectors in flashlight body).
I've not got any problems with the practicalities of connecting it all up. The end cap cannot be screwed into the light engine but as it happens the flat part of the battery tube is quite a convenient place for a removable handlebar mount.
My concern was centered on whether there might be any problems using a NiMh battery pack. If no, this will make a very simple to put together and long running bike light. Much cheaper and superior to most of the commercial ones.

I might be off base, but I thought the MRV was all about throw and very little flood. Do you currently have the light? From what I understand about the beam it doesn't sound like a very good pattern for bike riding.
Just a thought..

I've got one of these (from DX). I put a bit of old inner tube over the body of the torch (to stop it scraping the anodising off my bars) and used one of those livestrong-type rubber bracelets to attach it to the bars.
It does bounce around quite a lot, but long story short- yes, it is very much all about the throw. I've got a smooth reflector so things might be very different with the OP one.
Good as an emergency light though- you could probable signal passing satellites if you got really stuck!
Am going to try the same with one of the cheap 3-cree torches from DX or Kai, or possibly try a triple-rebel light next. The rebel should provide a bit more flood at least- can't find any suitable reflectors anywhere...

I've got some old HRM mounts that have flat tops which mate flush with the flat part of the battery tubes. Used with sturdy rubber bands they makes a cheap and easily removed set up. Even better, I've got an old Cateye LED flasher and mount. One half of it can be self tapped to the flat tube, which can then be used with the standard handlebar mount just like any commercial arrangement. I think most mounts could be adapted like this if you don't mind having a small bit of plastic permanently on the side of the light. Most of these mounts have very little depth, so they wouldn't cause a problem carrying the light around off the bike.
