Reef nutrition

What's a good 14K 250W SE MH bulb?

Hmmm. Haven't tested many bulbs, but when Dave came over the readings seemed pretty good. Shallow tank and good reflectors didn't hurt tho. It was like 225 under the middle of the reflector and like 300 where they overlapped. That was maybe a foot or 18" under the reflectors, just under the water surface
 
I just picked up 2x 250w SE reeflux since Robert had some in stock. Compared side to side with my radium and it looks almost identical! Running it on a lumatek ballast set to 250w, the radium is set on hqi. Not sure what the PAR value is but it looks good to me. Of course it has not had a chance to really burn it yet so we'll see if there's any color shift.
 
I was doing some research on the reeflux 12k but after reading Sanjay's article I plan on going with the Ushio 14k's. However, there's a good amount of people who are happy with the reeflux 12k's.
