New Lumen Bright Reflector. ... any info on them

thanks.....yes, i ordered the black, 16x16 HQI reflectors. i can modify my canopy easy enough, i havent even finished painting it yet. i think what i'll do is either hang them from the ceiling or make a new bracket off the canopy to hang them higher. i definately want to reduce the amount of light spillage into the room and thats why i figured getting them closer to the tank would help. thanks for the advice, it gives me some good ideas to start with. i might end up building a "floating canopy to house the reflectors (they are a bit industrial looking) and yet still maintain the open look i want for the tank. i'll post pictures of what i finally come up with. thanks again...tom
 
Here you go, Tom.

I asked this question earlier in the thread but it got buried. I've got a 36"x30"x21" sps tank that I want to get new lights for. I'm set on getting a single 400w Reeflux 12k with the coralvue ballast, but I can't decide whether or not I want to use the large lumenarc or the large lumenbright to give me the best coverage and intensity. Any thoughts?
 
Those 36" tanks are somewhat difficult to plan lighting for... especially when you're talking 30" front to back. I think if you use 1 large LB, the sides of your tank will be dim. 2 mini LBs mounted close together would give you your length, but would probably be lacking front to back. 1 large LA would light your entire tank, but you will be sacraficing quite a bit of PAR.

If it were me, I would probably mount 2 large LB as close together as possible... even though they will still be overhanging your tank by 2" on each side.
 
now that is a sweet canopy! while beyond my meager woodmaking skills, i think i can come up with something simular. is that your tank melev? very nice! just the look i want. is that tank plumbed through the wall like mine is? great way to hide all of the equipment/sumps/refugium/etc. thanks for the perfect example.... you da man!

monti, i am no expert on reflectors here... just getting my first decent ones this week, but from the reading i've done here it sounds like the lumenarcs give more spread while the lumen brights are more directional. i opted for the more directional to hopefully have less light spillage outside of the tank, i'll let you know how it works out this weekend.

What is your rock work like? Can you post a pick of your current setup?

Ok guys for those of us who don't need this kind of detail which should it be. My dimensions are 84X28X25. I plan to use se 250 watt 10 bulbs with VHO atinic sumplementation. How any reflectors are required for complete coverage. Thanks..

Ok my math or just my self in general was off yesterday and thought you had a 10ft tank.:rolleyes: But with the tank only being 7ft I would say go with 4 LB larges but they will need to be raised so that the bulb is at least 18 inches off the water. You could go with three but I would go with 4 if it was my tank.
 
I don't have a FTS of my tank right now. My tank is set up with a center back overflow with the rock arranged like an island in the center of the tank. All three sides and most of the back are open. Now with this set up it would seem ideal to have a bright spotlight focused on the center of the tank. However, as you can see from my avatar I'm a big clam guy, and most of my clams are arranged in the sand around the island. So coverage-wise I'm leaning towards the LA since I only want to use one bulb, but I wonder if there really would be that big of a difference in PAR from the large LB.
 
I am interested in what Monti is saying b/c I am getting a 36x24x24 rimless and would like to only have 1 400 w 12k reeflux in a LB large if I could.
 
Guys thanks for all the information you provided. I need to sum up. My furniture hasa already been ordered so I must build my lighting around a 14" canopy. The tank dimensions will be 84X28X25. I would be grateful if I could get comments on how to build my lighting for the new tank. I want to use SE 250w10k with VHO Atinic sumplementation. Here is a picture of my existion tank hat will be moved into the new one. For thoser of you tired of seeing this picture I am sorry. It's the only one I have.

LBs will not look right or you will not gain the great bennefits of this reflector in a 14inch canopy. Even with Lumen Arcs your canopy will be a little too short IMO. If anything I think you should go with LA minis. LBs need to have the bulb at least 15 inches off the water.IMO

I think you would be better with 2 LB minis with 250s. But since you want to run a single bulb you will have to go with the 400 with an LB large and hang it high in order not to cook your tank and to gain a spread of 36 inches.
 
I would go with 4 but you might be able to get away with 3 if you place your LR right under each reflector. But having The LA low will also hurt you in spread and is why I suggest getting 4.

Lumenarc III is the answer for you. You'll cover the entire tank with no problem. All you need is the bottom of the pendant 10"-12" off the water surface.
 
So are there any high quality reflectors that do not require the kind of clearence you mention? Unfortunately a 20" canopy in not very appealing.
 
That size canopy is really only ideal for VHO or TFs IMO. You can always put some parabolic reflectors in there. But better off with T5s or VHOs in a 14inch tall canopy IMO.

That picture is of a reef tank I visited in South Dakota last fall. I posted quite a few pictures from that trip here on RC, probably in the correct club forum, or in Goodwin9's thread since he was my host. The owner's username is DakotaReef, if I recall correctly. The wooden canopy not only could be raised and lowered, but the crown molding could be removed to get more clearance when necessary. It was plumbed through the wall behind, had a single MH bulb with four T5 bulbs on the four sides.
