Hamilton vs. Radium

[frlejo]

I was wondering which gave off the best over all spectrum between the Hamilton 20,000k 250 watt, & the Radium? I will be taking out my VHO's, that is why I am looking at the 20,000k's. thanks

I also haven't tried either, but one thing I want to bring up is that most people with SPS tanks that run Radiam bulbs use the 400W ers and overdrive them with HQI ballasts for a ice blue color. The 20K bulbs don't put off allot of light, so allot of people bump the wattage to still get the PAR.

I'm not sure if you keep and SPS tank or not, but if your switching from 10K's it's worth thinking about the fact that your going to cut your light in half or more.
