150w HQI bulb recommendation

[JeremyAN7]

Can anyone make a suggestion for a bulb that puts out quality light, and high par like Ushio 10k, but maybe a little bluer? I'm thinking in the 12-13k range. I've had 14 and 15k before and it was a bit TOO much, and sacrificed par..

ideas?

Radium

 

[JeremyAN7]

specs on the Radium please?

Ok, that seems to be a 20k bulb... so I'm confused.. If 15k was "too blue" with not enough "whiteness... how will 20k look? Honestly I have never seen a 20k bulb..
FYI. I have 2x VHO actinic.

The radium is more of a 15K color when fired on a magnetic hqi ballast. You really can't go by the manufacturer's color #'s as the vary quite a bit. You can check color and output of different bulbs here:http://www.manhattanreefs.com/lighting

i'd use a megachrome 12,500k or a ushio 14000k with the magnetic ballast...kinda yellow looking but unbelievable growth with them...is it a blue wave set-up?

 

[JeremyAN7]

i have a Catalina, but not sure who made the ballasts... just that they are huge and heavy (magnetic ) and hot... I assume that they also are not nearly as efficient as an electronic.. but.. next time.. meanwhile. time to rebulb.. So I hear Megachrome 12.5 or Radium.

I just got a set of Ushio 14K's for my 250 and it looks good. My corals started growing like crazy after I changed them.

anyone know how the Megachrome looks / works on magnetic ballast?

 

[JeremyAN7]

So I guess i'm down to Megachrome 13k and Radium 20k, but how to compare? on magnetic ballast?

Tough to compare as Sanjay has no data for the 13k. Here's the 10k vs Radium here:
