Here is the deal . . .
I have a giant glass tank filled with water, and my robot fish is in it.
I got two expensive high speed cameras pointed at the fish, 90 degrees to each other.
The problem I am having is poor lighting . . . the cam images are really dark.
I took all the office lights I can find and am pointing it through the glass, even bought 6 underwater fountain lights (3 stopped working for no reason, so lame) . . . but still not enough light!
I spent weeks looking for underwater lights, but apparently 'waterproof' in the marketing biz actually only means 'splash resistant' . . . dangerous, I know . . . so I ended up giving up on this underwater light idea.
So I am thinking of getting a professional studio light or flood lamp, hopefully under $120 . . .
Anyone with recommendations on lighting or where to get a studio light? Google has tons, but looking for anyone experienced with thoughts . . .

I have no idea if this would work but it says it's good for photo studios and it's under $120. http://www.buy.com/retail/product.asp?sku=203461497&listingid=15996209&dcaid=17902

I called them up, and they said it didn't come with a bulb or stand.
A very expensive light bulb holder, no? :P

if the camera's dont come with flash then maybe sync a strobe light with the camera?
-
is it possible to put the tank outside on a sunny day?

nm I found two really bright directional lights in the lab, and I just finished filming :D
maybe sync a strobe light with the camera?
I own a stroboscope that can do really high frequency light flashes, and I considered this option actually, but I have no way of easily synchronizing two cameras and a stroboscope simultaneously.
is it possible to put the tank outside on a sunny day?
even with no water in it, it requires a crane to lift . . . and it has to be in my lab so I can utilize all the equipment . . . my earlier experiments were done in a small home fish tank, right next to a big sunny window. the problem with windows though is green algae turns my tank green when sunlight is present . . .

So throw some snails in there :P
Would it be possible to get 2 strobes and have them go off and on at opposing intervals so its basically just a constant crazy bright light?

does the tank have a closed top? If not, why not just shine a light at it from the top?
