Please Help looking for light intesity graph

Do you have a graph on the light intensity reaching coral on an acual reef.

Sorry, but I don't.

I'll move this to the lighting forum instead of the chemistry forum.

Although this is not a graph there are some numbers which may help you:

"As a frame of reference, the amount of surface light on a coral reef is around 2000 µE/m2/sec, while that from a 175-watt metal halide bulb is about 200 µE/m2/sec. For excellent information on the lights we use and their PAR values, readers are directed to the recent writings by Dana Riddle (1997) and Richard Harker (1997)."

This is from the following link.
