Well for better or for worse i've ordered the 8800k, i just hope i don't botch the rewiring job i'll have to do to my aqualight.. it's a bit of a gamble but i've spent so much money on my aquarium already that i didn't want to compromise on the lighting.
I gave a summary on the lighting more as a help guide so hopefully others won't have to spend hours looking through forums like i did. hope it helps.

Thanks aquaverde. Its chinese made I think :roll:, and the whole set with bulbs was cheaper than some DIY on the netaquaverde said:

While you're on the subject of K rating and lighting types I've got a sort of unique lighting setup that you might have some input on. I've got a 125G with two 3' dual lamp CF fixtures (2x96w in each) and two single lamp 3' NO fixtures (1x30w in each). That gives me a total of 444w split into the following wattages and color temps: 192w @ 10000K, 96w @ 6700K, 96w @ Actinic 03 (420nm), 60w @ 6500K.
I use the Actinic 03 because I love the way it makes colors come out. And I love 10000K for the same reason. The 6700K lamps came with the fixtures in 50/50 6700K/10000K bulbs so I still use them. My question is, can the Actinic 03 cause any problems for my plants or select for algae? I've read that high blue spectrum light may cause more compact, short internode growth on stem plants but I have no problems with that - I just don't want to be providing any advantages for algae if I can avoid it. Thanks!

All plants and true algae have Chl a and have chloroplast.
These are what capture sunlight and use it to produce NADPH and ATP.
There is no light that selects for plants but not algae. There are very subtle differences in deep clear waters in marine systems that let one alga get a jump on perhaps a another species allowing it to dominate for a time.
Not exactly a valid comparision.
Atinics will not help nor harm a tank, wasted light in some respects.
Some claim blue produces compact growth, I've never seen any difference over some 2 years of growing plants with many bulbs. Cool whites do just as well as pricey "fish plant" bulbs. This was shown in green house studies and was a well done study.
It really gets down to aesthetics, do you personally like the color or not?
I like Triton bulbs the most, i have had ther 8800K and 5000K mix, I like that mix a lot but the Triton still is my winner. It's 7200K, not that it(K ratings) means much.
6700K was fairly blueish when they came but now people are saying it's yellow
If you like then atinic for the color, use it.
It's not going to make your plants grow better/more compact though.
Most folks like 5000-10000K ranges, some do not like the Atinics which have almost all the energy at 7100K. Some do.
I ain't one of them.
