This shot of some coral also shows the red halo around the perimeter of the light beam due to the dichroic nature of the filter - longer wavelengths (i.e. red) of light pass through the filter at skew angles
Really fantastic. Do you often go diving with the lamp?? I keep corals that fluores under uv, but have never seen them in the wild. Must be amazing!!!
