My new SST-90 dive light in the caves of Merritt Mill Pond

I just returned from a two week dive trip to Marianna FL, Diving in the caves of Merritt Mill Pond with Cave Adventurers owner Edd Sorenson and staff. We took my new build, SST-90 with Der Wichtel driver, side by side with top of the line lights from The Underwater Light Dude, and it blew the ULD out of the water, so to speak.

No photos, you'll have to take my word for it. Finally a sharp, tight LED beam that performs as well as a HID in water thick with particulate and other crud.

I am so happy, wish all my other experiments were this successful.
