Anyone know of a really good 250w de bulb? I was hoping to purchase a radium bulb but they don't make the double ended version. I have no idea why but whatever. I was pondering changing the DE into a mogul version (not difficult). Anyways are there any really nice 20k 250w de bulbs out there? If not, are there any others in a lower kelvin temperature? I head good things about the 14k Phoenix bulbs. Any insight? I need alot of light for my gig tank. Right now I'm currently running an 8 bulb 24w ATI t5 fixture with a reefbrite xho.
