We first saw this light at MACNA 2013 in Miami, users were shining life in the ocean and on the beach late at night. There is nothing cooler than seeing actinic blue everywhere when the reef culture come to town. Well the new version is out! http://www.shop.mediabaskets.com/Orphek-Azurelite-5-Watt-LED-Flashlight-OR00001.htm Orphek Azurelite 5 Watt LED Flashlight You can use it to view corals and stomatellas, mysis shrimp, amphipods, bristelworms and other creatures moving around your tank at night when the main tank light is turned off. For brilliant illumination and the fluorescing of corals for photography. To assist feeding corals at night—illuminate the coral you're feeding without causing the polyps to close up. Plus, there is a strobe to create lighting mode!
