Thanks @micheal_thomas1946 for testing the D28 3600 light during his wreck diving!
Features of this light: Max output 3600lm, Runtime up to 2.5 hours at Turbo mode.Max beam throw 550m with focused beam angle 8°. This light is a good partner for cave/wreck diving.
And the light can be used with the Goodman handles, also XTAR light handle:
