good replacment bulbs

I am looking to replace the bulbs on my Outer Orbit system. It currently has dual actinic bulbs and was wondering if anyone had any suggestions. Current bulbs are as follows: 2x150W 10K HQI-MH w/ 2x130W Dual Actinic & 6 Lunar Lights.

 

The halides or the t5's... Or both?

 

As much as I hate to admit this.... all the bulbs are over 2 1/2 years old

 

U want blue or white look... If blue, light blue or dark blue

 

Here is a pic of what they look like now w/ just actinics on. I don't know if this is considered light blue or dark blue but I would like to keep the same look.

 

For the halides, go with radium 20k or maybe Phoenix 14k.
The t5s are harder to pick now... You will probably want to go with ati since they have high par. Go with a combo of pure actinic, blue plus, and 75/25 bulbs. You may also want to throw a Fiji purple in there if you get serious about showing off coral color (reds pinks and yellows)

 

Would I be able to find a dual T5 like that? Or can I put single bulbs (x4) in my lighting unit? Here is a link to the unit I have..... which no one sells anymore and two of my lunar lights burned out so I'm trying to find those somewhere.

48 inch Current USA Outer Orbit 2x150W 10K HQI-MH w/ 2x130W Dual Actinic & 6 Lunar Lights

 

That would be a power compact bulb, not "dual T5"

 

Thanks
