Hi
I used to use a Mag light years ago, but found them to heavy and the batteries soon died !! I now use a Surefire 6P The beam is really bright, it runs off 2 x camera batteries, which are expensive but the weight is nothing and they will last for ages and ages.
I have it set up with a presel switch, the lead is short and doesn't get in the way.
I haven't got any photos, but if anyone is interested then just let me know.
Safe shooting.
