Where is a link for this testing? Regardless of whether a T5 or VHO, they are a Flourescent bulb. The T5's "tech" is the same as a VHO's tech...both a "flourescent" bulb. It is the power that is ran through the bulb that makes it different (Normal Output, High Output, Very High Output). The more power ran through the bulb, the faster the phosphorous coating on the inside of the bulb breaks down and the faster the spectrum change.

I find it interesting that everyone brings up Iwan's tank in the ongoing T5 debate. Iwan does more than just give his tank light with T5 bulbs. He uses Zeovit and I think there might have been mention of using Prodibio, or in other words...feeding. The point is you take a MH bulb and a T5 bulb and they dont compare. What is the different between using VHO's on a tank and T5's? Technically there is more output with a VHO than with a HO(T5) bulb.
Why not just use VHO bulbs on an SPS tank instead of T5's?
