best 400 W 10K bulb for best SPS growth?

[supervdl]

What is in your experience the best 400 Watt bulb with 10k in terms of best SPS growth? What balast do you use - mine is electronic?

 

[rockindacheeks]

since noone will chime in... XM 10K

 

[supervdl]

Do the XM 10k work with electronic ballasts?

 

[ReefRockerLive]

Yes the XM 10K will work on your ballast.

I use 3 XM 10K 400's over my tank and I get very good growth and I love the colors of my corals.

i use a reeflux 10k for growth along with a xm 20k for color. noticed more intense color when adding the reeflux. everything seems to be happy and growing great!

i like Evc -10k ,they not so yellow as Xm's// And have great PAR reading..

 

[Bryan]

For growth... Iwasaki 65K, but you may not like the yellow...

EVC 10k and Reeflux 10k would work on my electronic ballast?

 

[Baros]

I've used BLV/Ushio, XM, EVC 10K's on Icecaps, all are excellent for growth & color. HTH.

I tried 400w xm 10k on the blueline e-ballast for 5 minutes, but the color is more or less like Iwasaki 65K, returned the bulbs back to Marine depot and been running the tank with two XM 20K, except the growth couldn't be much happier .
