Lighting combonations?

[akm]

Right now I have a dual 250 watt 6500K setup. There also 4 vhos but I have to send the ballast in to get fixed. So I'd like to have as much daylight vhos as possible but also have more of a blue light color. If I had 20K halides and 4 10k vho's would that still be blue and would the par loss be so much it wouldnt make to much of a difference. I could also get 2 15K halides and 3 10K and 1 actinic. Or pretty much any other way. Which way would turn out the bluest but still have a good par rating?

I have 2 15k 400 watt and it looks great enough blue in my opinion.....

Id keep the 250 settup but switch to XM 10k's and install four URI super actnic VHO's. Par on the 15k's is a bit on the low side compared to the xm 10k's. Of course, this is only a real issue if youre into sps/clams and such.

Would the 10k's be with 4 actinic be closely the same in par to the 20K's with 4 daylights?

[JimD]

No way.

[akm]

Which one would be more?

Lightng is a very controversial subject, I strongly suggest you do a little homework.

I have two 400watt 10k XMs over my 75. There is NO blue look about them, just the brightest light you have seen! lol. I run two 110watt actinic VHOs and you can just barely tell that they are on when the halides are turned on.
