Hi,

200uE/m^2-s = 200uE/(s*m^2). Its just notation -- I just screwed up a little bit.


As for what depth does 200uE/m^2-s...it is about 30m under the surface.

From the experts:
Discovery Bay In Jamaica.
Surface = 1925 uE/(s*m^2)
15m = 392 uE/(s*m^2)

Great Barrier Reef
10m = 490 uE/(s*m^2)


FYI, these were measured independently..but...

1000 uE/(s*m^2) for 4x110W of VHO (at water surface)
1100 uE/(s*m^2) for 4x96W of PC (at water surface)
