10000k is my favorite. I dont like the pick look of the 14k or the blue of the 20k.
whats the diff between SE and Double ended MH? I like the simple DE
I think Woodstock was referring to most 175w 14k and 20k bulbs by makers like Hamilton and XM, Coralife, and Ushio. I also never liked the dark purple/blue color of those bulbs and another reason why i always went with 10k in the past. The Reeflux 12k in 250w changed all that for me. First off the 175w appearance vs. 250w are completely different. I also have no doubt that a 175w Reeflux 12k bulb will look completly different from the 250w. The Radium's only come in 20k 250w or 400w. To get the colors i am seeing 175w would not have enough push and make the tank dark.
The Radiums i have are not making the tank blue like other bulbs of a higher k rating. It is blue but real. Even the 250w Reeflux 12k has a sythetic look to it compared to the Radium's.
I hope i explained that properly for you all to understand.
Again, For my tast the Radium's have the best look without compromising coral coloring or growth. Both have exceled since i have started to use them.
I did want to comment on the 250w Giesemann MegaChrome E40's.
Afer seeing JFK's tank under them i became curious. He show's two pictures with and without supplementing. I beleve this not to be true. I found without any actinic supplementing these bulbs are more on the 6500k side then any other bulb i have used. I realized i was right when i read a few posts in Professor Sanjays tank thread. He is notorious for keeping his corals under 6500k sacrificing visual appeal for overall coral growth and health. After seeing hs tank under these bulbs the white/yellow apperance was exacty like i experienced with these bulbs.
