Not quite the third bulb yet. The second bulb is still working its just that the glass reflector part of the bulb has cracked and wont take much more abuse. Its not really the torch or bulb at fault its the muppet who owns it and keeps dropping the damn thing
At some point when I can be arsed and get a quiet day at work I will put my engineering skills to good use and make some kind of protective cover for it or knowing me and what a cowboy I am I will just wrap a few 100 rubber bands around it...hang that isn't as silly as it sounds.
Back on to what torch. Spent as much as you can. Not alot of point going diving if when you get to the bottom you can't see sod all because of the darkness. HID is IMO the way to go. The light it gives off really brings out the colours, the others tend to be a bit orange which of course gives stuff a bit of a orange tint.
