I found that the GE Daylight Ultra 40W NO lamps that I use on my Icecap 660 are also comparable to the URI Aquasuns, with the exception of the slight coloration difference.

I suspect that the Icecap's ability to overdrive the NO lamps, and it's alleged underpowering of VHO lamps to preserve the life of the lamps makes them very comparible output wise. We'll soon find out when Darren puts that new light meter to work.

And interestingly, if the latest article about intensity vs color holds any water, we might all be switching to overdriven (on an Icecap or DIY ballast) NO Ultra Daylight 6500K lamps for less than $5 a shot vs $42 URI Aquasuns! I know I will!
