i think the 12k coralvue are nice, worth checking out at least.

I love the colors I get from Radiums, but the life span doesn't thrill me. However I still use them on one of the tanks. Now the 12K Coralvue Reeflux iis not only is it bright and a nice crisp color, it is run on the CV E-Ballast. Best of both worlds I guess. Corals seem to love it too :eek2:

yeah, give me a few months and i will try out some other bulbs. at the rate i am going it will be 1000w though. my 250w setup barely made it 3 months until i felt the need to change them

Tim, are those MJ mods?. How are they working for you?. Can you pm me your parts list, thanks. Sorry to highjack.

I have 2 400 watters in my tank powered by Magnetec ballast. One is xm20k and the other is a radium. Both look pretty much the same (very blue). XM 20k is a bit brighter though. Like it's been said the radiums with hqi looks much different.

yeah i will pm it you tomorrow, tired of typing for the night. well if you xm is brighter than the radium, and i feel the radium is brighter than the helios, then maybe i need to buy a xm to compare a little more. gonna have to get a par meter so i can start doing stuff like sanjay, : j/k

I saw the 250W Reeflux 12K at the LFS, it's nice and bright and colors were awesome...they were running them on electronics didn't seem to know the brand.... I only wish Sanjay tested them so we would have PAR values... Coralvue say the 12K has the same performance as the 10K with more blue...

I think you guys just talked me into saving for a set of 400w halides! I have been thinking about this for a while. The whole problem was having room for both the actinics and the 250w halides. The PAR on the higher kelvin bulbs was just too low IMO so I decided to stay with my T5s....I really think going to the 400w is the answer. Higher kelvin bulbs + high Par 400w + No Actinics = Win......I will deal with the heat with fans...I think I will be oK

Horace,
You wonÃ"šÃ‚´t regret it. Radiums are my recommendation.
Good luck!
