It depends on your tank dimensions. If you have a narrow long tank, mounting it up higher would cause some light spillage from the front and back. For my 235gal display tank (72" x 30" x 24"h), I have them mounted 15" but I do get some slight light spillage off the left and right sides but I'm too lazy to remount them.

I love your deep red Goni (?) On the right. And I would definitely buy these lights if I wasn't 3 years out from building my tank. 96Lx36Wx30H (120" long if I can get the go ahead from the wife). I was wondering how many you recommend for this size tank? Would 8 (additional 2 on the end if 120") lights mounted parallel to the front panel in 2 rows be sufficient or some other configuration?
Second quesrion; Do you intend to develop a new light in the next 2/3 years?

If you're tank will be mostly SPS, I recommend 6 Extremes for 96L and place them in perpendicular and 8 Extremes for 120L tank.

Thank you for the quick answer. Yes I did fail to mention that it will be an sps dominant mixed reef, but it will take a while to fill out as it will be huge (I hope) and I will be starting from scratch.

I don't know if you forgot to answer my second question or neglected to answer it on purpose. Do you intend to develop a newer version in the next coming years? If so I would like to see a slightly longer model in this line. I think this would give your line more modularity opening up for better coverage in certain situations (like a 36 inch wide tank)
I have another question which may have been mentioned but I don't remember, I do remember you wearing the fan's duty cycle is controlled based on the temperature of the LEDs but how many hours is the fan rated to run for at max speed?

Yes, I'm working on the ReeFi Uno but the coronavirus outbreak have delayed the process. My normal operation is to inspect at the beginning of production and mid production in person so I can catch and resolve production issues before they are shipped to the US, but with the pandemic, I won't be flying overseas anytime soon.

Fan speed is controlled by 2 temp sensors (one in each puck of the LEDs) and uses ball bearings which have 3x the life of sleeve bearings in typical fans. I believe this centrifugal fan lifespan is rated over 7 years at full speed. Unless the room temperature is hot or heatsink fins are clogged with dust, fan would only need to run at a small fraction of full speed, so the fan will last even longer. I do recommend taking the unit outside to blow out the dust with compress air can every 9-18 months or whenever you hear the fan spin a bit too loudly.

I greatly appreciate your answering all the questions on this forum. I like the product you have engineered very much, hopefully I didn't get you to announce that you were working on an improved product outside of your design. The new(ish) philips lights that is coming out looks to be an attractive choice but I just don't see a passive cooling system, even with such a large heat sink, to keep the LEDs nearly as cool as your products.

The upcoming ReeFi Uno will not be replacing the current ReeFi Duo series. Uno will have 1 puck of LEDs instead of 2 pucks in the Duo.

Thats the same effect as having a larger unit with 3 pucks, you would just have to get a second unit to accomplish the same goal. That being said do you think having 3 pucks spanning a 36" width at a depth of 30" would be beneficial or would 2 be sufficient for SPS?

I’m super impressed with these light fixtures. Out of curiosity, how many and which sized Reefis would you recommend for coverage of a 36x24x24 SPS dominated mixed tank. I’m currently running a halide/t5 setup but the side glare is blinding. Been toying with the idea of replacing the halide/t5 with ReeFi.

I recommend 2 ReeFi Due Extremes in perpendicular to your tank length.

I think 2 would be sufficient but more at same overall intensity is always better. If you want 3 pucks using the Extremes, you can a front row in parallel with your tank length and back row in perpendicular.

I’m still very happy with my lights, coral and clams seem to like them too!

Any body else notice the 3 hot spots on the screen top from the intersection of light? I think you either need to rotate 90 degrees or move the lights further apart. A PAR meter will tell. Just curious and something I noticed in you photos. Rock work and corals look great. Light it is pretty nice too!

I see what you are saying... I will take a pic of mine tonight.. Maybe his lights are too high? If he's not having a problem with growth ….. you right a par meter will tell..

It honestly was an accidental observation. I was admiring the photos daydreaming and thinking about my lights arriving. I have a “floating” fixture that is 11” above my 120. I’ve been constantly thinking about mounting height and spread thanks to BRS, when I noticed that.

I’m going to have to rent a par meter I guess. It’s nice to have a resource like BRS has provided for products the sell. I may lower my fixture a couple inches when I mount the lights. But I like the room I have to work.
