I second flashlight reviews.com .. There is no single place here that displays all lights.
Your taste will change as you start to weigh out the differences in all the lights that are available to you, through manufacturers as well as custom lights made by some of our outstanding members.
My suggestion is to determine what exactly you would like out of a flashlight in terms of brightness, size and range you would like to see out of the light. It can get a bit confusing as you get deeper into the vast amounts of lights available to you.
After you do some reading you can figure out exactly what it is you are after, aesthetically pleasing to one could be very different to another..
As already mentioned, hang on to your wallet, you are about to embark on an educational and expensive journey.
And most of all, enjoy your stay!
