Is this for real? The T5 PAR measurements have been replicated numerous times on RC. Take a look at this thread - first page has a pic of PAR measurements IN THE TANK with a POS Tek fixture that isn't actively cooled (the increase in intensity with active cooling and quality reflectors has been shown to double the effective output of T5s):

I'd have to spend some time fishing for the other threads with PAR measurements of better quality T5 fixtures. Attempting to draw a comparison of VHO to a quality T5 is insane. The application of a quality reflector coupled with active cooling has repeatedly been shown to produce sufficient lighting to enable the highest light demanding SPS to thrive. As mentioned above, the effective output is nearly double that of a non-cooled lamp without individual reflectors.
If you need to measure it for yourself to feel comfortable, go nuts. I've also got an umbrella handy just in case you want to make sure that you can't jump from a roof in a magically contolled fall like Mary Poppins
