ATI vs Reefbrite T5 bulbs. Has anyone compared them?

[LostInTheDark]

I recently found out that Reefbrite is manufacturing their own T5 bulbs. On paper they look good but has anyone compared them to the known standard, ATI? They are quite a bit cheaper then ATI and Geisemann bulbs but that doesn't mean much if they don't perform or last as long.

Most T5HO fixture manufacturers make their own bulbs that are cheaper than Giesemann and ATI; IMOPE, however, you get what you pay for. None really compare concerning the rated Kelvin temp, spectral coverage, or longevity. While I've never tried the Reefbrite brand, I can't imagine them being any different.
