In reply to Dean:
I've had one for about a year - not sure how it compares to others in terms of xenon brightness etc but it's solid and i've had no probs. i bought it for a short-lived phase of fell-running at night and it's just about adequate if it's pitch black - i suspect that some other torches might have more powerful xenon bulbs but i've not used them. battery life's good, LED's last for 120 hours if i remember right and i got good life out of the batteries on xenon (more than they claimed) when i was using it every night for an hour or so. at the moment i use it mostly for walking and occasionally for mountain biking (in conjunction with my cheapo cateye halogen set which wasn't as bright as i hoped it would be!)
there's space for 2 spare bulbs behind the reflector and they're easy to change, black diamond also make a few bulb variations (economy, high power, etc) although i've just got the default one which the brightest i think.
hope that helps
