Can I cover 48x48 with two large 400w LB's? I currently cover it now with two 400w L3's.

If it were my tank I would run 4 250w LB wide minis. This would be killer coverage and optimal lighting all around. I bet you it would make a night and day difference compared to your current lighting.

BreadmanMike · 12/08/2008, 05:40 PM

I don't want to have 5 bulbs to replace. Three is enough.

I don't have anything in the front 8" and some low light stuff along the back. I think we can make two large work.

I'll have to get you over here.

Quick question... I have 2 LB 250w12k's on a 65g ant the bulbs are at 18" high over tank for about 2 or 3 weeks. do I always keep them the high on the tank or do I drop them down?

You can lower them to about 16 inches slowly and would also lower you photo period. Take things slowly and monitor your inhabitants. Any signs of shock raise the reflectors and allow them more time to adjust to your new lighting.

melev · 12/09/2008, 12:40 PM

No, they stay at that height. Perhaps 8 months from now, you could lower them one or two inches to get more life out of the same bulbs, thus keeping the same PAR value. Then when it is time to replace the bulbs, the reflectors are raised back up to their original height.

johnny313 · 12/09/2008, 01:25 PM

ok thanks but shouldnt I change them every 9 months?

melev · 12/09/2008, 01:41 PM

With a PAR meter, you'd have that answer. Most people try to use their bulbs about 12 months, I believe. If you are changing them out more frequently, then leaving them at the same height would be your best bet.

Pike614 · 12/09/2008, 02:14 PM

ok, JR..you've had awesome advise for the Reeflo 250 I've got, now I am thinking a nice xmas present would be a lighting upgrade. I am running 4 x 250W 14k MH's on ARO elect ballasts....over my 450g tank with simple spider reflectors. The tank is 30" deep. I was trying to decide between the Lumnenarc and the LB reflector as I think I'll get better growth from my SPS near the top/mid of the tank. ANy thoughts on the difference between the two?
Thanks!

What are the exact dimensions of your 450gal tank? The main difference between the two reflectors is how the disperse the light. The LBs concentrate the light within the bounds of the reflectors spread. The lumen Brights require higher mounting heights (with a benefit of dispersing heat) and does seam to penetrate the water surface better than most reflectors on the market. The Lumen Arc is ideal for maximum spread but does little to confine its light boundaries. Either reflector will be like night and day compared to your spider reflectors.

Pike614 · 12/09/2008, 03:01 PM

the tank is 8' x 30" deep, and 36" wide...I had 4 holes put on top, each is 17" x 24". This is an in-wall tank. Seems then like the LB is more of a spot light, good for 2" width tanks?

JRaquatics · 12/09/2008, 04:18 PM

4 LB larges would be optimal for your tank. The LB minis are good up to 30" wide tanks and the Largest seem to be good for up to 38"-40" wide tanks.

Pike614 · 12/09/2008, 05:15 PM

thanks!

Pike614 · 12/09/2008, 05:30 PM

just to be clear, even though you said that the Lumenarc 3 was a wider spread, you're saying you'd go with the large LB for my tank at 36" width?

nickts40 · 12/09/2008, 05:41 PM

There is no chance in hell that my corals would grow that fast in a year. Still trying to figure out the secret. They grow longer pretty good. Just not branching or fatter.

JACOXVIII · 12/09/2008, 09:17 PM

what LB would i use for my 155 bow front
canopy is 18"off the water with a open top
2 250 CV ballast and 2 xm 20k had 12k reeflux and think i will go back but will need sup for a bluer look with the 12k
o ya will be getting a 3rd cv ballast

I suggest The LB larges because although the spread isn't as large as the LA the quality of light penetrating the water surface to your inhabitants will be greater. You will get enough spread for your system if the reflectors are hung at recommended heights. I am a big fan of the Lumen brights and find them to be the #1 key to the success of my own reef.

What are the relative dimensions of your tank?

JACOXVIII · 12/10/2008, 01:46 PM

i will go see
but the tank at the ends is wide as a stander 150 think 18"
and in the mid it is 24" wide

72x24x24 in the middle and 72x18x24 on the ends if it's a AGA 155 bow.

Well I would say your best off with 3 250 LB minis over your tank for optimal lighting.

sgrosenb · 12/12/2008, 07:05 PM

Quick question - I've got a 156g tank which is 60x24x24. Brand new, so it's just starting out (nothing in it - yet!).

I'm getting 3 Lumenbright 3 mini's, and I'd like to know how high above the tank I should hang them, and how far apart I should space them.

I'll be doing mainly SPS, but I'd like to be able to do just about anything else too.

Thanks!

melev · 12/12/2008, 10:01 PM

Scott, you didn't state the wattage of the bulbs, but 16" is a pretty safe bet from the bulb to the water.

The reflectors should be evenly spaced across that 60", do the center of each one would be at 10", 30" and 50" roughly speaking. Obviously you can tailor that to how it lights your tank best.

johnny313 · 12/13/2008, 08:42 AM

hey JR...I just noticed the RS sent me 15K bulbs instead of 12K. I looked at the bulbs before they were turned on because as I turn them on one is a different color so i tried to read the bulbs and noticed they have 15K written on them. is 15K ok?

Now I'm really confused. I was going to hang mine today at 18. Guess I will just experiment. 250 refflux 12k X3 over 84x24x30 with 6in sand bed. Both ends will be in the shade as I will place the three together in the middle of the tank.
