Raduim HQI bulbs

Recommended Posts

I have been reading good things about the Radium 20k HQI bulbs. Whiter than most other 20k's with a higher PAR. Anyone using this bulb and have any comments on it?

So if no radium available...any suggestions on what would be the closest 20k

On what kind of ballast though, HQI?

 

 

I think everyone over on RC was sayin the coralvue ballast was the best bet... probably be worth it to scan through the big reeflux thread over there to make sure. They had a problem with bulb consistency a while ago, seems to have been fixed, specially the 12ks. Some people had 10ks looking very pink.

@spanko -- those progression pics are great -- really cleared up a lot of questions I had about said bulb. On post 13, u have the phoenix and radium comparison -- at what point of the 'total hour' usage are both of those bulbs in each pic?
