To date I've been most happy with ATI lamps over the Giesemann and Aquascience I have used in the past. I'll probably stick with one KZ Fiji Purple regardless of what I do though.

I have heard about how popular the fiji purple bulbs are. Are there any negative impact on the coralls, since the bulbs are not a true blue light? What im noticing from my tank now its too much white light. I have also read how the fiji purple bulbs will make the collors stand out more. Its something im considering to add more of a vibrant color in my tank.

Nope. Perfectly safe. High PAR values too. You can't go wrong with this bulb!

Actually, there has been some published research that shows lights with a large amount of red spectrum inhibit zooxanthellae reproduction rates: http://www.advancedaquarist.com/2009...earchterm=None

With that said, I still use one Fiji Purple knowing this is likely a negative consequence because I like what the color does for red and purple coloration.

Yeah that's the "BS advertisement disguised as a 'study' " to which I was referring above.

If you look at the link provided by Canuckgod420 above: http://sites.google.com/site/tfivetesting/par you'll see the PAR values are no better than ATI lamps.
