Yeah, I get the joke, but the joke is only funny based on an assumption that is incorrect... the not funny part. That error in assumption is that I am trying to prove Lumenarcs are the 'end all' and that nothing compares. I never said that, or even implied it. Or is that just another one of your jokes? :rolleye1:

I dont know for sure if the Brights are better than the Arcs but without testing its hard to say. I never had owned full size Arc but have owned the minis. The full size Brights are brighter for sure but Im starting to doubt the spread. When I first installed mine, it was hard to tell since all I had was just some very white marco rocks. I figured a pair of full size brights can cover a 5' long tank. Not so sure now though. Without a Par meter, Im not sure what the reading in the middle would be. Cant tell just by looking but once I set the EV(not sure what that means) setting on my camera to its lowest point, you can see the middle is not as bright as the rest.

Maybe I just need to raise them up a bit.
There we go... thats what I was talking about... the spread is less with the 'brights and the 'arcs it seems. Is one brighter than the other? It doesnt seem so... just more focused. In which case, on duece's 5' tank, they may not be the better to use (unless you want a light area and dark area... that depends on the intention of the owner). I can say that two lumenarcs would cover that 5' long tank more evenly... thats for sure. That doesnt mean I think one reflector is better than the other (at least ScubaTC gets it...lol), just that both have their applications.
I just think that the 16% claim is BS... thats all. I wonder what that number is based on anyways. Im betting its a 'peak intensity' value. Whoopie... I can get 2x the intensity of an 'arc from a PFO mini pendant near the bulb because its a more concentrated reflector... that doesnt mean anything though. All Im trying to say is 'buyer beware'. There are plenty of companies that will try to sell you stuff based on marketing hype that just doesnt add up. This lumenbright might be the real deal, dont get me wrong, I think it is actually... its just 'different'. FWIW, I doubt moving the reflectors up will do much to improve the spread on the 'brights. They seem to have a very narrow focus with all those facets. There is very little light that comes out of the reflector at an angle... just the light coming directly from the bulb at an angle actually, none of the light coming from the reflector.

From the tank it would seem that if you had coverage of 2 foot it would be more feasible to opt with the lumen bright. If you have 2 1/2 beyond the lumen arcs are more efficient in spread. This is great to know if making a decision like Deuce 67's tank. I personally am going to try out the lumen brights on my 120 4X2X2 and after viewing Deuce 67's tank believe I made the right choice. I would still love to see a comparison shot though with the same bulbs/ballast and different reflectors -

Lumenarc Reflector (12 facets)
LumenBright Reflector (24 facets)
Sean's DeathStar Reflector (over 100 facets)
I win, I win, I win!!!
Actually, I do have 2 of those - but please get this thread back on track...
No more of this "I'm right, you're wrong and I can prove it in my next 20 posts". I'm smart enough that I can decide what to believe all by myself.
I want to see people who own the LumenBright posting pics and giving 1st hand accounts and impressions and actual before/after comparisons.

Actually, you forgot 1 facet in each reflector. That, and The deathstar pic isnt working.

I didn't count... I took the numbers straight from ReefExotics website.
The image works fine for me and a few co-workers on different machines.
Thank you for proving my point. You cannot leave a thread alone without trying to prove someone else wrong and yourself right.
Now somebody please post more pics of these new reflectors in action...

Sean I completely agree with you about Hahn and his superiority complex. I have another mini in the mail that will be replacing an Aquamedic 250HQI DE with 14k Phoenix. I will be putting my other 400watt Reeflux 12k in like previously seen in my other post. I will post a picture when it is in place and functional and offer up my comparison on the light spread difference. Obviously the wattage increase will add to it but I will take that into account. All of the wiring is in place already to hang a 400 with parabolic. Maybe I will do that and take a picture to compare apples to apples so to speak. This hopefully will be completed by this weekend.

Looking forward to more comparison pics SlowCobra - Thanks!
I wonder if these can have a port added for heat exhaust like the lumenarc. I'm asking because before I noticed the 'Brights I was planning on getting the 'Arc minis with glass and A/C duct port. If I go with the 'Brights I'd like to know if I still have this option.
Right now, I have to leave my 6' canopy hood open all the time to allow heat to escape with two 9" fans blowing straight across the underside of the 400w bulbs. Although the canopy has icecap fans installed on each side to pull air in one side and out the other, this was not enough. I like the idea of being able to use exhaust ports in the reflectors themselves. So I am still on the fence trying to decide between arcs and brights.

I can tell you that my Mini with the SE 400 is WAY cooler than my 250 DE. So much so that I am not afraid to move my 400 out of the way where as I am almost certain to burn myself with the 250's. I am not sure if you were to put a glass shield in place how much that would change. But I have the bulb in the mini about 11 inches off the water in the picture I have posted.

Instead of name calling, why not prove the guy wrong? It sure would appear that he has posted relevant and valid information in this thread.
A few of you have done nothing in the way of addressing those points. Instead you have made unwarranted personal attacks that have nothing to do with the subject matter. Frankly it gets more than a little old.
The reflectors in question have a different focus. Hahn has pointed out that this MAY (and will) create different light gradients in the tank and/or higher incident light values at certain spots.
He has also pointed out that without meaningful measurements over a 3D grid, we can not tell what unit is more efficient.
You guys can all take pictures and ooh and ahh about what you see. nobody is stopping you. However, SOME OF US desire to talk about the subject with more detail.
So where is the rub? When you say "A is better than B", be prepared for somebody to actually answer the question with science and logic instead of opinion and name calling.
