Which 20K 250w single end bulb
I got a new PFO pendant today. I like the color of the XM 20K but it's not bright enough.
Which bulb do you Recommend. Like I said, I like the really blue bulbs like XM 20K, but it has to be brighter. |

Depends a lot on the ballast you have.
Is it an M80 HQI ballast, M58 250 watt probe start or MH electronic ballast? |

I really like Reeflux 20k bulbs. I had my tank set up with 2x 400w XM20k and 2x 250w XM20k but switched each pair out for Reeflux 20k about a year and a half ago and haven't looked back.
EDIT: Good point about the ballasts. My 400w is a Hamilton dual ballast and my 250w ballasts are Icecaps. Visible spectrum / color is the same on my tank between the two which is what I was hoping for. |

I read all this debate on ballasts and radiums. I have a 250w radium on a m80 ballast right next to a radium on a galaxy electronic selectable set on 250w Hqi and I can tell no difference whatsoever in the color.....

Really wondering about the Ushio 20K though. Have not seen any pics for them, but users seem to love them! |
