FStoppers has published a review of the Lume Cube, a continuous LED lighting cube that is waterproof down to 100 feet. The Lume Cube has a color temperature of 6000K, 10 different light level settings and can be used as an optical strobe. The light itself can fit in the palm of your hand or be mounted to a camera as small as a GoPro.
Jennifer Tallerico reviewed the Lume Cube for FStoppers and as a tool for her underwater product photography for her studio JT Noir Studios Aqua Underwater.
