Yeaa... 13" arms I could live with, but 33" arms are a little ridic haha. I think 1' to the subject is a little too close.

No the filter goes on once you are in the water so that there are no bubble in between. The design of the SRP dome was more intended to make it look cool but ended up being unpractical as you can't put other accessories on and it has now been abandoned. It is a bit of an issue for companies like SRP trying to make something that at same time is feature rich and looks cool a bit like the tray that also has a design that is counter productive if you use light as requires even longer arms. The light you mention (and is not possible to talk about the quality of the beam without testing it) should work well up to 40" from the lens and would require arms 21" long with a tray one foot wide to operate properly. You can see that you need very soon wide arm as the angle goes past 60-70 degrees
Well at least I got it right pertaining to the filter. Now, if you don't mind, a few more questions. 1) You may have covered this but what is the formula for distance of light from lens based on degree of of the beam? 2) I am shooting video in caves...any suggestions? 3) In order to get max distance without backscatter do I want the lights back of the lens, beside it or forward of the lens? 4) I was using two 21w HID lights with plastic (homemade diffusers and was getting pretty good video). I changed one to a video reflector. Should I have extended the arm for the light with the reflector? Thanks again for a great thread.
So another question. Could you not just point the lights more outwards vs straight ahead to move the closest minimum distance further away?
Archon's wide angle is pretty hard to beat bang for buck.
Interceptor, what do you think about these?

You have me puzzling over Angle of Beam now!
