EdgeDiveTech has designed two new products- the Edge Ultra100 and the Edge Ultra200 to lit up the undersea world . The Edge Ultra100 is a single canister light, which provides 9,000 lumens of light with its 80 degree angle. In addition, it has a burn time of 2 hours, is rated to a depth of 500ft (152m) and features wet connections between light head and canister, making it possible to change battery canisters underwater.
