Looking for ideas on light placement and luminarc size.

I won't get into the technical jargon...I will only say that the pictures I posted of my tank made a believer of me and I suck at pics as most of you know.

As for a store owner...not this guy. Is it a bad thing to pass on knowledge I have gained from someone? I thought this forum was to help others learn the hobby??? I guess sharing my knowledge is now percieved as a butt kisser to the store owner? I heard this same stuff back in the day when I would speak highly of Rod. To clarify, I still think Rod is a great guy and a wealth of knowledge and always will. It's a shame that people read between the lines and don't take this as information and nothing more.

From that thread it seems that Hahn seems to really know his stuff...of course he could be wrong, but he gives some very good points

:lol: Yeah Hahn has been non-existant on that thread since the real pictures came out and pretty much convinced everyone. Read on Tony!
 
I won't call anyone out here, but after reading the thread that Tony referenced, many of these posts are plain sales pitches.

Whois will tell you WholePet Market
 
Mark should have let you know that the manufacturer recommendation is a minimum of 10 inches from the bottom of the reflector to the surface of the water.

How do you know he didn't?

Can I please ask everyone to keep the store plugs out of my thread? This is nuts. I get told multiple times to call a specific person for help because he sells something. Then I state a fact of who I will buy from if I do buy them and people start poking at that too.

If you are not here to help me with an unbiased opinion that does not plug a store please get off my thread. WT$ Luminarc's don't grow coral. Thats the dumbest thing I ever read on here.

Have you really read the whole thread? Man, I can't believe you can stand my longwinded dribble for more than a couple pages:lol:

Now you are just being rude. I never called anyone dumb. And if you took the time to read you would see that in your SPS dominant tank that the light 1.5ft away from the bulb is worthless. What I explained was you won't be able to grow SPS there. OK, maybe you might be able to maintain some deepwater coral. My mistake. I gave you a great tip Ted and never even got a thank you, even if you were not going to do it. You were worried about your center overflow. I gave you answers. This is the same dung that we keep seeing here on RC . People trying to help and then they get bashed. Thanks a lot Ted :(
 
Maybe you should try helping without going after people.

It is annoying to have my thread turned into an add for a store.

It is also annoying to have someone that was trying to help me called out in the thread for absolutely no reason.

Also my unusable light from my current Luminarc's has my SPS looking great even in the lower areas of my 30 inch deep tank. My problem was at the edges and under the braces. Also next to the overflows.

I read on, and from what I saw, it seems like Hahn was the only one that seemed to know what he was talking about. And seemed to get bashed because of it. I'm not trying to take sides, the lumenbrights probably do look brighter in photos but that is because the light is concentrated straight down and won't give you the spread the lumenarcs provide. I just want Ted to know what others are saying, in hopes he can have a more informed decision...

Once again, who knows, that could be totally wrong, but from the evidence I saw Hahn seems to be correct...
 
I don't ever recall plugging any store on this thread. I don't care where you get LB's from. I just think people should be using them. Buy them from Reef Depot, Reef Exotics, or wherever. This is unimportant to me.

"I" have been testing these with an Apogee PAR meter and not a LUX meter. Seems to be enough evidence for me and a lot of others that are switching to LumenBrights.

Hey, to each their own. If you have a small canopy and beieve in the LumenArcs, so be it. Keep 'em. When I am done with my testing on a large Lumenarc and LumenBright side by side I will post for the last time here. I already know what the numbers are showing on both so it wonh't be a surprise to me.

Canar,

Not surprised that you are getting decent light in the middle considering the crossover light and the bulbs being 7 inches off the water. Heat,UV, air circulation and evaporation should prove to be a bigh problem there. Wish you could raise your lights a bit. Oh well. The point was made and you confirmed that you are having trouble with light off to the sides where there is no other reflector. Maintaining coral and growing coral are two different things. Good luck and I am out...

"Every inch counts"

WOW, what happend here? Back to helping CANAR. Hans was right and wrong at the same time if that is possible. Jon states that the reflector directs the light strait down. This is true. He states there is a hotspot, this is also true. But to burn corals, I don't think so. If the sun doesn't scorch corals, man made light definetly won't. I rather light up the organisms in my tank than light up my room. The numbers produced by the LB show that it infact does direct the light in the tank as LA often bleeds to the outside environment rather than the tank and produces lower number as a result. I have owned both reflectors and I am a firm believer in the Lumen Brights. But Lumenbrights are not for all aquariums/people and may infact not be for Canar.

As for CANAR, he has an unusual setup. I have pondered his setup since the first post. If you can raise the LB reflectors on the two ends of your tank, you will concentrate the light within the tank/corals and not the outside. I think you need a cross spread in the center of your tank though. This is were luminarcs spread comes to be beneficial. The only problem is the light will and does have a hard time going through the tanks braces. you almost have get the light to go under the braces.

What is your canopy structure like?
 
There is no way I can get my canopy to get any higher. I am basically stuck with the height it is. I would have to basically rebuild it of I wanted to raise it up.

The weird part is the angle the bulb is at does have a large effect on the spread. I did not see that on any of the charts on that thread. Maybe I missed something?

I may keep these still and mount them 90 degrees different then they used to be. The light I get shows double when I do this. Yes maybe my meter does not give exact PAR ratings but it does tell me where and when I get more light.

Another question is angling the light so it is not exactly level to the water line. Does that effect the penetration? If I do that I can shoot under the cross braces some too.

I do like the penetration the lumenbrights have. They basically give me the same spread as the small Luminarc's with a good deal more light. Anyway you look at it I am ahead of where I was before I started this thread.

I do want to say I really do appreciate ALL the help here. There are so many cool people on here and so much knowledge it is great. Sorry if I got touchy last night but I was really starting to feel pressured. It also seemed like it was turning into an advertising thread. It caused me to do the same thing back plugging the stores that help me out. I am not sure why that keeps happening on here but I would much rather keep the plugs out of this type of thing. They are much better served with the "Look at what I got from XYZ" threads. Just my 2c

Interesting find. Will you be posting some pics of of you lights mounted at an angle? So are you thinking of mounting two LB straight down and then two LB in the center at angles? I am very interested to see what the light looks like in the tank and the meathod that you are using to mount them on an angle.
 
So here is what I am leaning towards but I think I will still at least "TRY" a full size luminarc first before I finalize this.

Top view of the tank. Lumenbrights 2 on each end with the bulbs in the position shown as it makes a huge difference. The big reef Optix fixtures on either side of the overflow.

Then I am going to use hooks and wire to try and get them in this position. Please excuse the crayon type drawing of the side view.

I look at it this way. Right now I am shooting light into the glass on the end of the tank. If I angle the lights it will put the light more into the tank then on the glass.

Thoughts?
 
How much light is diffused threw your braces with the LB reflectors? Do you think you can eliminate the reef optix if you place a 2 luminarc in the center. I understand that you don't want to lightup your overflow but I am thinking about bulb replacement cost and added electricity used.
 
Just trying to pop out some ideas, not too sure if it is even helpful. What if you move the two side reflectors in more, but keep them at that angle. The place the two center ones closer together but place one closer to the front and the other closer to the back. What is the maximum height can you mount the reflectors in your canopy?
 
The most I can get is 7" from the bottom of the reflector to the water. When we designed the canopy we did it for Luminarc mini's. That was the big oops I think.
 
I canopy was built the same way. I ended up cutting large squares in the top. I will eventually create a box molding the hide the exposed reflectors. I am glad this mistake occured because it helps with the heat within the canopy.
