This is the best lamp comparison website I managed to find during weeks of research into something I made more complicated than it had to be. Just view the photographs until you see the beam that you like and remain blissfully ignorant of the science behind lumens and footcandles. I ended up buying a Tiablo A9 with 53mm collimator head which throws a tight beam right where I want it.... on the target. The spillage from my previous lamp simply illuminated an escape route for my prey, while now they pause to consider leaping into the darkness. This hesitation is usually fatal.
The website is for comparison only and it's up to the individual to track down a supplier. I'd be glad to help if anyone has any difficulty in finding who supplies their intended torch.
