400 watt bulb advice

[Reefer Rob]

Bulb choice and color are a personal preference, everybody likes something different. With 400w bulbs I haven't noticed a decrease in growth with a higher K bulb, if anything it's been the opposite. 400 watts is a lot of light!

I've been trying to match the color temperature of my halides with what I get with 1 blue+ and 1 aquablue T5, but I haven't found the bulb yet.

Bulbs I've tried so far with Icecap ballast(no actinics on):
XM 10K- too yellow
Aquaconnect- too blue
Reeflux 10K- too red
Radium 20K- as blue as my moon lights
Plusrite 14K- don't even want to go there
Ushio 14K- Perfect when first installed, but shifted just a touch too yellow after about a month

I'm thinking about trying Hamilton 14K or Reeflux 12K next.

Rob, what ballast was driving the Radiums? I ask because I used the Son Agro ballasts and the Radiums were perfect. Certainly not blue like moon lights

That was with Icecap ballasts. I've seen Radiums on HQI ballasts and they look great, I think they need the extra power.
