All-in-one perfect MH lamp

[Ceak]

I am going to have only one bulb over my cube with no supplementation so I am looking for an all-in-one bulb with good coloration, brightness and enough PAR... So far I've narrowed down my choices to:

- Reeflux12K
- Radium 20k
- Helios 20K
- AquaConnect 14K (if all else fails!)

*On 400W HQI (430 HPS) ballast.

I've seen the 250W Reeflux 12K on electronics and it looked real nice, fairly bright with enough blue to bring out some nice colors... The only drawback on this bulb is the fact that Sanjay didn't test it... I am wondering if it has roughly the same PAR and spikes in the pink/red spectrum like the 10K version has... Can anyone comment on growth or looks for this bulb in the 400W version?

All information and/or opinions will be greatly appreciated!

phoenix 14k is probably your best bet for good par and good color. 20k bulbs rarely have good par......

phoenix 14 doesn't come in a 400W and both the Helios and Radium 20K have as much PAR as the Pheonix (on HQI ballasts)...

Basicaly what I am asking for is some feedback on the 4 bulbs I mentioned, especialy the Reeflux12K...

anyone?

no one is running the Reeflux 12K or Helios 20K!?!?

Since you are using a 400W HQI ballast, you may want to use the Radium bulb. I believe those other bulbs are probe start lamps and would likely burn out much quicker on that ballast.

Finally some new tests!! The BLV 14K is a PAR beast! Unfortunately I need something bluer...
