burton14e7 · 09/13/2008, 04:25 PM

My mini's are 16 1/16th wide

reefguard · 09/13/2008, 04:27 PM

16 x16 x 7 is the reflector. Not sure about the pendant.

reefguard · 09/13/2008, 04:29 PM

I will stick with the 175's on the outside and put the 250 in the middle for my new set up.

If these refelector will allow me to use 175's all the way accross the new tank and be able to keep light loving SPS then i will just go with another 175. What do you guys think?

Thanks,

Yes, the difference is incredible. The PAR under one particular bulb was 145, and with the new reflector and new ballast, it was 444. Had I increased my lights as you suggested, that coral (Toadstool Leather) would have been cooked alive.

If you have access to a PAR meter, it would be good to test the values in your tank. Here are two pictures from my PAR testing. Remember, the first picture uses "spider" reflectors putting the bulbs at 9" off the surface of the water.

And now, the Lumenbrights putting the bulbs at 18" off the surface of the water.

Look at all the space I have now.

When I ran mine, it was 2 hours per bulb per day for the first week. I increased it 30 minutes each week until I was up to 6 hours per bulb per day.

So I didn't have to look at a dark tank so long, I staggered the timers so that as one was about to shut off, the next one was on. And I've really grown to like it.

reefguard · 09/13/2008, 07:11 PM

I have raised the tp of my hood temporarily only because I am upgrading in about a month or so. The light bulb is now 12.5" above the water level in the tank. Is that still too low with 175's?

Noel

melev · 09/13/2008, 07:16 PM

It depends. How does the tank look? Do you see shadows? Remember the closer the bulbs & reflectors to the water, the higher the PAR. You'll see those numbers posted earlier in this thread, as well as the article Bubbletip2 wrote for Reefkeeping. Have you read it yet?

reefguard · 09/13/2008, 08:15 PM

No, I haven't read the article. Is it on line? The tank looks good. The only shadows I see is where the powerheads are mounted and where my return line is.

could you please tell me what the height of your pendant is?

glxtrix · 09/14/2008, 07:41 PM

Noel, my 175's are 12" off water, however as you can see in the article I have 3 that are placed really close to each other so shadows aren't really an issue for me. My tank is 55x24x24

brshriver · 09/15/2008, 08:46 PM

Anyone on pros and cons of the mins vs full size? I am putting them over a 210G tank - 72x24x30 - and need to mod the canopy either way.

melev · 09/15/2008, 08:50 PM

My tank is a 280g - 72 x 30 x 30, and I love the large reflectors. I'm thinking for your tank being 24" wide, minis would be the better choice. Let's see what Jim suggests.

bubbletip2 · 09/15/2008, 09:08 PM

I agree. Minis would be fine unless for some reason you may upgrade in the future and will have a 36" wide tank which I feel you would not be as optimal without the larges. You can certainly fit them on. Just remember your overflows will get a little extra light. 3 minis should do fine if an upgrade is not coming or you don't mind buying new if you do upgrade. You can sell LumenBrights pretty easy and still get most of your money back. Also, if you are ever thinking supplements on 24" wide than minis are in order. I have a 54w T5 on the front and back of the tank. Hopefully that helps...

elvn · 09/15/2008, 09:33 PM

The one I'm putting up is 60" x 30" x 30". I bought three minis for it after discussing it with several people with lumen brights. Mini sounds small by name but 16" plus diameter really isn't that small in my opinion

Its going to have supplemental lighting like bubbletip said. Two 4' 14k vhos on each side of the middle lumenbright row. Since the MH photoperiod on lumen brights will be small and ultimately max out at 6hrs, the supplemental lighting will be the only lighting on the tank for up to 4 hrs a day (~2hr before MH, ~2hr after). It will also help light the front and back of the tank a little better during the overall photoperiod.

The lumenbrights are going to be:

250w 12k SE ----- 400w radium ----- 250w 12k SE

I'll post back with results but project timeframe is getting longer than anticipated with other overall projects related to ultimate display tanks + sumproom design.

lol

bubbletip2 · 09/15/2008, 09:50 PM

That will be a really nice tank and the minis will do fine. Add six more inches wide to your tank and you would be wanting the larges. Yeah, mini is probably not the right name. Small sounds more like it. I am already saving for my upgrade 300g - 72"l x 36"w x 27" or 30" h. Possibly 96" l, but we will see.

Good luck with your build. Definitely post back. Nice bulb selection. I was possibly going to keep a 400w ballast to do the same in the middle and either throw an 400w XM20K, Radium 20K or Helios 20K. Maybe for the next tank.

reefguard · 09/15/2008, 10:16 PM

thanks glxtrix. I will do the same. I will start my upgrade starting next week. i am picking up a 180, i need to build the stand and canopy and i will use my 175's on the side then put a 250 in yhe middle.

Noel

brshriver · 09/16/2008, 06:31 AM

Thanks for the feedback everyone!

I am using supplementals so minis sound like the way to go. I'll order a regular for the replacement reflector for my frag tank since it is 30x30 and has no canopy.

Perhaps they should be called regular and large instead of mini and regular

I have a 110gallon (60 x 18 x 24). It currently has 3x250W MHs - two in a combination 4 foot hamilton fixture and one in a stand alone pendant over the last foot of the tank.

Will two minis give me enough coverage w/ 250w on that tank? It sounds like it. It is an SPS tank.

Bubbletip2

Have you done any testing with the EVC ballast and the Reeflux 12K Bulb combo?

Thanks
Kevin

bubbletip2 · 09/16/2008, 07:58 PM

I have done some testing and will again on my 30g cube. Currently I am running a 250w EVC ballast on an EVC 14K bulb under a large LB pendant. I can certainly swap out bulbs and ballasts and post some numbers. I would also like to use the Coralvue ballast in the test as well. If I remember correctly, the Coralvue ballast was approximately 15% stronger with the 12K bulb than the EVC ballast. I was doing a lot of testing during that time and never wrote anything down on it. I was just testing to see where my levels were in the tank at that time and to refute some data on an EVC 14K bulb being stronger than a Reeflux 12K. Yeah right

chad508 · 09/16/2008, 09:42 PM

ok i have a few ?'s i am starting a new tank which will be an aga 120 48*24*24 i plan to use the 2- 400 watt coralvue dimmable ballast and 12k reeflux bulbs i currently have. i am going to purchase 2 lumembright reflectors and was going to see if the large would give better coverage over the smalls in a tank only 24" wide. i do not plan to upgrade as i am downgrading to this tank. also what height would be best bulb to water to get best spread and coverage.

bubbletip2 · 09/17/2008, 06:52 AM

If you can raise larges up to 16" minimum you will get better coverage over the smalls. If you can't go higher than 14" than you will get better coverage with the smalls. If Larges are at 14" you will stil cover most everything it is just that the crossover light between the two reflectors will start lower so you will not have as intense light between the two. If you don't plan on putting coral in between the reflectors 9"-10" from the top than you are fine with larges at 14". You can typically see the cones created by the reflectors and see what an inch or two will do for your crossover light. The other thing you can do to prevent lack of crossover light is press the two larges against each other int he middle. On a 48" tank you will only have 4" on each side not getting full coverage, perfect for LPS or coral that don not need as much direct light. I have 3 minis on my 5ft tank pressed against each other with 6" on each side and it works well.

Because the larges are 20" in diameter it is easier to have the outsides of the reflector beyond the edges of your coral allowing for light to hit the coral on all sides and angles.
