I've used flashlamps or torches for as long as I could walk. For business, I always look for the best available and have been through a few I can tell you over the years. My latest purchase is from RS, a UK company. They are renowned for selling good kit to the professionals and the two torches in the video are NOT an exception to the rule. What do you think?
