A few weeks ago we posted an article about the Orphek DIF-100 16,000 K 100 Watt LED Pendant along with some PAR readings from an Apogee PAR meter. The photo and video below is a demo we did over a 55,000 gallon public aquarium display with an iphone 4 (sorry for the lower quality video quality but I think you will get the point).
Watch as the 5' black tip reef shark passes from left to right and how the color changes as the shark passes from Orphek DIF-100 16,000 K LED light to the existing T5 lighting setup. We will be doing another demo next week and I hope to have some better camera equipment when I visit them again.
