For its size, PHOTON of America claim nothing can match the power, strength and miniature size of the amazing PHOTON Microlight. Trials of a variety of leading Micro-Lights were conducted in the New Forest of Hampshire, and on Dartmoor military training areas in Southwest England by Lieutenant Commander Alan Cronin MBE and Mr Colin Towell (an ex SERE instructor and Royal Navy survival expert). The objective was to find the best Micro-Light for covert and military use. They compared the performance of six micro-flashlights and their summary was, "That where the situation requires an evader to signal his location to a rescue unit using a micro flashlight, that the flashlight of choice should be the Photon Micro-Light". Further comments from the trial were, "Due to their superior build quality and waterproof integrity the Photon Micro-Light outperformed the other units on test". Batteries included.
