The purple coloration is just from the bulbs color. wait until the corals actually change colors. Mikes frags that he gets always seem to morf into some really intense colors after some time under his lights.
New Lumen Bright Reflector. ... any info on them

Well my pic may be skewing that for you. It looks a little washed out and in person looks a bit more natural if you will. It's bright for sure as you can see. I wish I was better with the camera so you could get a better view of it. Sorry for that. Where's Jim when you need him.
You mean something like this Todd
This mille has four colors and maybe more - it has peach, pink, blue and possibly purple, and green tips - gorgeous. Mike was generous enough to give me a piece of this beauty. Thanks Mike!
And this Teal Table Acro was cut in half from the TOTM. Mike was able to spare a piece of this for me too. You think?
This beautiful Red Mille is at 840 underneath a salt crusted brace. Beautiful coral also and Mike gave me a big chunk of this. I had wanted a piece of this since I first saw Mike's tank. This Mille is feeding in this shot. It looks like sap that came out of the coral 5 minutes after Mike fed the tank. This is just one of many coral in Mike's tank that displays this behavior.
I love this shot. This purple acro is at 392 half way down in the tank with the whole top of the pillar shading the back side of the reflector. Gorgeous coral.
Well here are some good examples of coral receiving this type of laser beam light and thriving. The coral in Mike's tank has really colored up since the TOTM. Still the pictures don't do the tank any justice when you see it in person.

I couldn't agree more that Mike's tank has many photo opportunities. It is definitely my favorite tank to shoot. Thanks for the complement Todd! If I ever make it over I can show you a few tricks on your XTi. I have an XTi also, so I know it well. So just curious in that you have seen Mike's tank a couple times. What do you think of the color of the pics in comparison to what you actually see?
These LumenBrights seem to help quite a bit. If I can speak for you Mike it seems your tank is doing better than ever.:thumbsup:

Any help would be appreciated.
Although the pictures are great, I don't feel it shows Mike's tank 100%. It's just that nice in person in my opinion. The colors of his corals are simply amazing.
I know first hand from seeing Mike's tank and now having my own LB's, that the color of the tank is more crisp. Once I get my water issues sorted out, I hope to achieve what Mike has with the coloration of corals.
Jim, great pics, I just looked at them again....I am jealous...

Here is a shot with a black background - it is under 400w however.

Hi all
I have been following along for this whole thread.
Great job to everyone who contributed.
I wanted to show how I mounted my LB's thinking it might help the others who were asking about mounting. Rather than wood I opted to use an aluminum "U" channel and then used adjustable hight hangers to suspend the whole thing. These pics were before I read here about the optimal 16" hight. I think they are about 12" off the water in the pictures.
Hope this might help someone in the future....

Thanks drudude!
Coral color is possibly dependent on several different things. Proper feeding is certainly a big factor in coral color along with lighting.
I use a 250w 12K Reeflux over my cube and have to say that my coral has been changing color since I started using this bulb. For example, I have an Acropora Nobilis that was a greyish brown color. Within a week I had ice blue tips and now half of the coral is ice blue up the stalks and coralites and it has doubled in size since I got it a couple months ago. I also had a green staghorn that is now turqouise with green polyps. I beleive these bulbs have really helped my tanks, especially with color.

In the spirit of bringing a thread back to its theme, I thought I would expand on some thoughts I expressed in the beginning of this thread in relation to the spread of a LumenArc being useful only a foot away from the bulb. The graphs that Sanjay provided sync up with the photo I am about to show. Just to refresh everyone's memory of the graph I listed:
At the surface of the water 18" away from a 400w XM DE 10K bulb showed very little light. My argument is that our coral does not sit on the surface of the water but obviously below it. If you have a 24" deep tank, there will be little light on the bottom 12"-18" away from the bulb. This something that seems to be a non-issue when using the LumenBrights as shown in the PAR tests on several tanks so far.
This photo was taken at a local LFS that has 22" Diamond Light reflectors(much bigger than mini or large Lumenarcs - original design). This particular reflector housed a 400w XM 20K bulb and the bulb was 18" off the water. If you figure it this way the measurements were taken 1" above the surface and 8" below the water. If this bulb had to penetrate 16"-24" of water, I am sure it would not be optimal for an SPS dominant tank.
You will notice that 12" away from the bulb, there is a significant loss of light and 18" away shows absolutely no usable light. This is the point I tried to make to Hahn. The Lumenarcs or Diamond Lights really only provide diffused aesthetic light if spread is important to you. It is very noticeable that the spread from the LumenBrights is more than adequate for most applications. Also, it is important to note that raising the LumenBrights only helps spread and allows for intense lighting where raising a Lumenarc to 16" will not be optimal for SPS Dominat tanks. Lumenarcs must be closer to the surface of the water to provide the intensity that is necessary. Again, this will prove to evaporate more water, heat up you tank quicker, put more UV onto your coral,, leave less room in the canopy for maintenance as well as air circulation. Beign able to raise LumenBrights and still get more than adequate PAR ratings is the real beauty about these reflectors.
Here you go:
I am planning on doing some side by side testing with a Diamond Light and LumenBright to show further the 16% increase that has been claimed by the manufacturer. It will be in the near future. Not sure exactly when I will be able to get everything set up.

Hahn, have your thoughts changed at all regarding the lumenbrights?

drudude - for what its worth, sanjays testing shows that the iwasakis 175's work better with the ARO ballasts, and a lil bit better with the EVC's....I think those were 250W ballasts tho running the 175W bulb. My conclusion on that tho because I couldnt find a 175W EVC ballast. In any matter, I run the 175W Iwasakis powered by the ARO ballasts and LB reflectos and I LOVE it! Will be getting new bulbs after thanksgiving and shouild be able to get a PAR meter around then too...man I cant wait to see how these things perform with my bulbs.

He would be correct and my mistake. The picture listing a 22" Diamond Light is incorrect. That is actually a LumenArc III recently purchased that measures 19.5"x19.5" as I just called the LFS and confirmed with the store owner. Sorry about that guys

anyone have one of those fancy par displays for the 250w bulb? I have a 24" tank that I just installed this over and they're really, really bright. It hurts my eyes (not joking) just looking at my tank up close for a while. I wonder how high the par ratings are on the bottom sand....
