You can excite coral and other underwater organisms to make them emit a brilliant fluorescent glow, thanks to the black Sola NightSea LED Dive Light from Light & Motion. It outputs 750-3000mW in a fairly wide 60° flood beam, and 425-1700mW in a tight, focused 12° spot. The light features a dark blue color close to the edge of the visible spectrum, which stimulates certain forms of sea life to make their proteins and minerals fluoresce.

By placing the attached, flip-down phosphor filter over the emitter window, you change the light to a standard white beam for normal illumination and underwater color correction. It's highly recommended that you place a yellow barrier filter over your dive mask, in order to block the blue light emitted by the NightSea and view the brilliant, colorful glow of the sea life. You're in luck, as one such filter is included with the Sola. If capturing images or video with your camera, pick up another barrier filter to place over your lens or port.

The light is submersible to 328', giving you plenty of room to explore the ocean's mysterious depths. It runs on a rechargeable lithium-ion battery, which provides a run time of 70-280 minutes depending on the output setting selected.
