Really nice pics those, what sort of exposure time did you use, and it looks like 2 sets of P7 lights? Was each one just 1 x P7 or did the lights have more than one?
I had 3 x lights. each one had one P7 driven at full power (2.8A current). I think the top photo was only using two of the lights. The bigger chamber shot below it had the 3rd light providing general area illumination from back near the camera position.
