"Nocturnal Lights SLX 800i Video Light with Flex Arm Adapter was what I bought on black Friday at the 20% discount. I think I messed up when I did the order as it was set to ship to my PO box, but the Nocturnal team fixed that and it arrived safely at my home.
I've had it on 3 dives, 2 daytime and 1 night dive. The day dives were full sunlight with good visibility in our Puget Sound (green water). The light brought out the color when I was close enough to my subjects. At night it lit up the area very well and my night videos were full of color. If you want to see the daytime video (2 minutes) go to http://www.seahorsediveclub.com/default.aspx
and look for "GPO's at Redondo" on the right with the photos. It is of two giant Pacific octopuses I saw that day."
