400W XM 20,000K

[Pman]

Can anybody tell me a bit more about the 400W XM 20,000K bulbs? I have been running 400W Radium 20,000K bulbs for years...but when shopping for a new bulb I came across this one at HelloLights and had quite a bit of hype about it. Any help would be appreciated!

Here's a picture of my new reef with a Radium and Coralvue 20K bulb. I know you asked abou the XM. I have a buddy who showed some pictures of the XM and CV bulbs. The XM was bluer on the PFO HQI

BTW, this picture is PFO HQI
