sunny, do some research on the bulbs and balast combos of the 400 watters.
youll be surprised and dissapointed that many combinations will barely provide more light than a 250 but still put out tons more heat and use tons more electricity.
so getting the right bulb, ballast, or combination is extremely important. if not, your upgrade could turn into a downgrade.
good luck

Sunny, the older luminarcs used to have clumsy sockets for large 400W bulbs but they've fixed that some time ago... Check the Pacific Garden Supply forum for more info. I'm pretty sure that if you still have to older version they will change the socket free of cahrge...
And if you're going for 20K then 400W is good, of course it will generate more heat but it will be much brighter and yuo will have alot more PAR than if yuo went with 20K 250s...

Trust me, I know what im doing.
My current 250W 10k XM's provide 137 PAR. If I were to switch the bulbs to 250W Xm20k's, keeping the sam ballast I would have only 72 PAR. With the 400W M59 ballast I will be getting 128 PAR, basically the same PAR I am currently getting with my setup only nicer looking and bluer.
Basically, the new lighting system will have the same power as the old ones but look nicer.

Basically stay away from "bargain" bulbs and you'll be ok.
The sockets are the same.
check to see if you have the variable mount mogul--ie the bulb should be centered in the fixture and if it is set for a 250 you may need to move the mogul back a bit. Mine didn't come with that, but rather seemed set for a 400 to be centered.

You know...the "look" and "performance" that earned the Radium raves was the fairly white look of the bulb on the HPS ballast. Course since the bulb is really only a 360w bulb apparently (per Radium's website), running in on the 430w HPS really hurts the bulb.
As for radium vs XM and "looks" or "better", frankly all that stuff is subjective. You say tomaeto. I say tomahto. I don't like the look of the radium or the XM 20k so.....
