Operating underwater lights with a remote can be a cold, wet chore. Infrared (IR) signals scatter the instant they hit the water, forcing you to fish the fixture out—dripping, awkward, and disagreeable.

Dr. Sparrow’s Fountain-Light Saber solves this with a four-foot fiber-optic extension for your remote, delivering commands directly to a light’s sensor with minimal signal loss. Reach, aim, and change colors—while keeping both your hands, and your remote, warm and dry.
