Hi all divers,
I just returned from Diving in ElQuseir, Egypt. There I tested a HiTec Fluorescence lamp in Night-Dives. I have constructed the lamp with parts of Sandwhich Shoppe> McR-20 reflectors and stepdown coverters (Shark Buck 3A). The emittors are 4 blue OSRAM SMT modules (4 LEDS per module each). A desciption can be found on the PR-Page of OSRAM under Success Stories http://www.osram-os.com/osram_os/EN/...ence-lamps.jsp
On my home page
http://www.uni-due.de/zoophysiologie/ you will find an explanation what the technique is good for and also a 12 minutes movie (stream).
For Fun-dives the technique it is a new underwater world. It is the magical transformation of drab-colored to brightly glowing color-saturated specimens that makes fluorescence so magical.
The diver gets the impression that he (she) dives in underwater flower garden. This is indeed the case since my lamp illuminates larger areas in contrast to commercial available lamps with one LED only (16 in our lamp, 16fold brighter).
Also on YouTube you will find the movie about this technique. From 6 hours night dive I have selected the highlights in this 10 minute version. http://www.youtube.com/results?searc...rch_type=&aq=f
