In my 15 years Dive time with about 600 dives I had some Torches either himself bought, or borrowed from diving colleagues. The Subgear Diving lamp Prolight SP30, however, those that impressed me the most. It is by your size and unassuming but shines like a large and expensive dive light. I use it as a main lamp and thus impress my buddy, who are amazed with your big and bulky lamps on the luminosity of Subgear Diving lamp Prolight SP30.
