Who told you that you had to cut the ballast cables down to a foot? That's completely false, at least from an electrical point of view (maybe they didn't want you tripping over long loops of cable on the floor..?)
New Lumen Bright Reflector. ... any info on them

Alright,
The recommendation from the manufacturer is to keep the total length of the cable around 8 - 9 ft in order to reduce signal loss when the ballast fires up the bulb initially. The manufacturer has found that a 16ft total cable length can make it difficult for the ballast to fire the bulb properly.
When I installed my ballasts, I cut my mogul socket down to a foot and connected my ballast cable giving me about 8-9 ft.
Please don't cut your entire cable length to a foot

The recommendation was for a CV ballast and bulb combination. Every manufacturer may have their own optimal installation requirment. Magnetics are much different than electronic ballasts in the way they fire the bulb.
This thread really needs to get back on track to talk about reflectors...

I was over at Mike's today with Jeremy - JRAquatics taking pics and measurements of Mike's tank. Mike's LumenBrights are set up so the bulbs are 14" from the surface of the water. I thought the measurments would be no surprise at this point seeing everyone elses 400w 12K Reeflux measurements. It was preety surprising to see that he is showing 399 on the bottom of a 30" tank on the front glass. Another shocking measurement was the 1863 1" above the surface of the water which is actually 16" from the bulb in the measurement because the sump return pump was off and dropped the water 2 inches.
I think many here will be surprised to see this beautiful Blue mille showing a PAR value of 1212. This blue mille was half the size two months ago when it was transplated in this spot when the tank was reaquascaped. Believe me when I say this picture doesn't do it any justice.
This stunt should only be done by trained professionals. Please don't try this at home!
And here is the left 3 reflectors tank shot:
Some really interesting numbers. 399 on the bottom front glass of a 30" deep tank. Like I said before, the possibilities are there for 36" and 48" deep tanks with these reflectors.
And most surprising is the red mille at 840 measured 8 inches under the surface of the water and especially under a 1" acrylic crusty brace that is pretty wide. Mike clean that thing off man. Just kidding. Mike actually brought up that this is a good way to acclimate coral under the brace. Great idea, Mike! We really should have measured after cleaning it off, to see what it showed.
And last a measurement taken in between the Red Acro on top the middle pillar.
Well, I think there is enough here to show that 400w 12K Reeflux bulbs, LumenBright Reflectors, Coralvue ballasts are a great combo which can certainly grow coral to the point that it is noticeable every two weeks and colors that will blow you away. I want to see what the 250's can do with these reflectors. We'll have to see soon...

Which pictures are you refering to drudude? If it is the blue mille shot than that picture does not do it any justice. The full tank shots I have tried my best to get it to look like it does in person.
If you are interested in the look of these bulbs check out the September TOTM and you will see a really good representation of what these bulbs can do.

Morning bubbletip2,
Ya i was talking about mikes tank (sept TOTM), the color pops, i cant belive how good it looks. I would love to get that kinda color, as you know i was going for the 175w, but i might have to go with 250w for the color, and sarifice a few dollars on the electricity side. As long as the color is the same as the 400wers.

You should see it in person.:eek1: You know I think there is something to say about the blue background on Mike's tank. For some reason it seems the blue background may cancel some of the blue light out in some way when viewing the tank causing the bulbs to look so natural - like swimming in the ocean on a sunny day. On my tank with a black background it seems the blue light is a little more visual but still a great look none the less. Definitely not as blue as some 14K bulbs. The camera seems to like the look in Mike's tank 
Hopefully that helps. I know electricity is expensive down there. Consider the 250's drudude and maybe run them for less time like 6-8 hours and your coral should get the light they need for photosynthesis. You could run some "good" led's as your lights prior to and after the MH's to save on electricity and so you can view your tank longer.

I just got my lights up and all I can say is WOW
They're everything stated and then some. I had 20k xms before and they were too blue, and then I've been with xm 10k for a while, now I have the 12k reflux bulbs and the colors really pop. The light seems to travel deeper into my tank then my old setup did as well. Money well spent...
Anybody looking for a good deal on these lights should talk to Mike (acropora nut), I've been very pleased with all the help and advice he gave me on the setup I purchased from him.

Like Jim stated these lighting combo throw a good punch. I was even suprised at the numbers we were getting. I also noticed when I was there was the massive growth rates Mikes corals arre getting. He stated it is due to the Reeflux bulbs. And now he states that he is gaining even better growth and coloration with the new LumenBright reflectors. I couldn't agree with him more. I can't wait to get the par reading from my tank with the 250s.
BTW it was good meeting you Jim.

Drdude,
I honestly have never seen the 175 watters in person. Mike from Reef Specialty might be able to help you out. I would like to hear what you decide.
bubbletip,
Im going to be doing a build thread in the large tank section. Im just doing a lot of reserch. i just found a thread with the 175W Iswasaki they look fantasic but i dont think they make the color pop like the 12k reeflux so thats the way im starting to sway. ofcourse there is the heat issue aswell. Im really trying to stay away from a chiller and the 175w Iswasaki with icecap ballast is looking like a winner.
OHHH THE DESISIONSSSSSS!!!!!!

Hey Rickyb,
It actually would not make sense for the manufacturer to cut the ballast cord because the ballast cord would be a lot more expensive to replace than a mogul socket. The mogul socket for LumenBrights can be used on any ballast, so it would be unfair to customers that want to use LumenBrights with other ballast/bulb combinations to cut them short. I don't see why you would want to use another ballas/bulb combination. JJ LOL!:lol:
