Thinking about replacing my 40w dual daylight with one of these 36w 8000k ADA CF bulbs. Is there a difference between the two as far as the way growth is affected or should I just hold onto the 40w?

I would be losing 4w but possibly at the gain of more spectral output in the necessary red/blue growth areas...

While the 36w 8000k ADA lamp seems to render better color for the tank (not that that means anything, just aesthetic), I cannot find a spectral output for this lamp, so if anyone has any info on it please share?
