im considering getting them as I like the bluer look and I was wondering if people are happy with them and the growth they are getting with them (specifically sps corals)

cheers

I would go with Radium if you want blue tint and more par, better bulb and worth the extra money

I though they were too blue.
But if you still go with them I have 2 of them that I used for a week sitting in my desk. PM me if you'd like to buy them.

I went with the Phoenix 14k's and they were perfect for me.

whats the difference in PAR with the bulbs?

XM is @ 53 and the Radium is @ 66 and if you run the Radium on a HQI ballast you will be in the 80's. The Radium will hold up better on a HQI ballast.

It deffinitively will give you a blue tint , but the corals POP:eek1:

I like EM!!:mixed:

I've used XM20k, Hamy 14k, reflux 10k, reefoptics 20k, and now Radium 20k ... their is nothing that can beat Radium in the blue bulb section IMO

 

[lechee12]

wouldn't the PAR numbers be dependent on the ballast green_frogspawn is running

[green_frogspawn]

Does Radium make a DE 20k cant seem to find one if they even make it.

 

[PaulErik]

Radium only makes the 250-watt 20,000K (AquaStar/Blue) in a single-ended version.
