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

Why is the par more under one of the lights?

Sorry about the double post.

you'll pretty much always have PAR value shift from lights due to age of bulbs, burn method or manufacture date. Just because you buy bulbs at the same time, doesnt mean the age is going to be the same.

How's it going?

I had gotten some used 12K Reeflux and we could not tell if they were the 1 month old bulbs or the 4 month old bulbs. After measuring I figured the one on the left was a 4 month old bulb as I put two new one's on a couple weeks ago and both are measuring over 1400 1" above the surface. This test was done 2 months after I fired up the bulbs.

I am actually currently testing the life of a 12K Reeflux by measuring each bulb 1x week to see how much they decline over time. After 6-8 months I will post the data.

interesting results. So it appears that the LB is brighter in a sense because the light is more focused, but the spread is smaller right? So these could be employed on deeper tanks to get the penetration/PAR needed down low correct? But they you would need more of them to get the spread, or do like I do and run them on movers.

I've got a 36x18x25deep tank with eurobracing, and after reading this thread it would seem the Lumenbright would be the best reflector if I were to use 2 of them close together. To go with a single reflector, the LA would be the better option. Does that sound about right?

Thanks for the info bubbletip2.

Went ahead and placed an order for the Lumen Bright minis/ Reeflux 12k combo from Reef Specialty. Great service and prices and even fast shipment. Really informative and very nice guy to deal with. Easily one of the best places I have ordered from. Also thanks to the others for all the great info on this thread.

so according to these numbers the lumen bright is really much better than the LAIII? Is it worth geeting 2 big ones for a 100g tank or should I go with minis?

BTW is lumen bright the same as lumenbrite III?

What are the dimensions of your tank? Yes, the Lumen Bright and the lumen bright 3 are one and the same.

My tank is 60"lx18"wx20"H
so is the lumen brite a lot better than the lumen arc?

In my opinion it is beter if you can apply the reflector properly to the set up in question. When set at the proper height for your application the numbers on the LB are simply higher across the board at that designated height.

Now if you have an 8"-10" canopy I think you will have trouble with either reflector getting a decent spread. Both reflectors need additional room to work effectively.

For your situation 2 minis up at 14" should be just fine because your tank is only 20" deep and 18" wide - if you went with the big one's the either reflector is wider than your tank and would kind of be a waste.

Do you have a canopy or is this an open tank? It is important to know because if you do you need to remember that the LB is 16" wide. Hopefully that helps.

open tank, planning to use them as pendants

 

[JRaquatics]

I agree with Jim go with the minis. LB Larges would waste your light output and decreasing the benefits of the reflector.

 

[burton14e7]

On a tank 24" deep would the mini's still be effective?

 

[JRaquatics]

Look at the specs that Jim posted on my 180gal. My Dem. are 24x24x72. More than plenty light.

 

[jnarowe]

I think the LB would fry a 20" deep tank.

 

[gigiba]

My tank is 92x27x24 (LxWxH). Should I go large or mini? and how high should I mount it?

I am planning to get 4 of these reflectors.

TIA
