So I have a 60 inche long Reef that is 30 inches deep and 24 inches front to back.

The A500X covers 36 x 36 and penetrates 24 inches deep. With the included 55 degree reflector, it reaches 30 inch depth but loses some coverage. I don't know what the coverage is with the 55 degree reflector.
I would need 2 at the very least. 3 if I don't use the 55 degree reflectors. Cost is $739 (740) per light.
That's $1480 for two lights. $2220 for 3 lights.

The A360X covers 24 x 24 and with the 35 degree narrow reflector that coverage goes down to 20 x 20 but reaches 4 ft deep.
I would need exactly 3 to cover my 60 inch tank.
The A360X costs $449 (450) per light.
The 35 degree reflector costs $39 (40) per.
That's $1350 for 3 lights plus $120 for 3 reflectors bringing the total to $1470

Am I seeing this wrong?
Are three A360X with 35 degree reflectors better for my 5ft, 30 inch deep reef AND less expensive?
Or am I missing something?

The biggest piece that's missing is that the intensity at 30 inches. The A500X is going to have almost twice the intensity at 30" down than the A360X would, even when you compare 55 degree with 35 degree reflectors.

Depending on what you're planning on doing, either of these would be good solutions. The A360X units would handle a mixed reef / LPS tank for a bit cheaper, where the A500X units will let you do wall to wall SPS in the entire system.

Let us know if that helps to clarify, or if there's more tank details you want to share - we can help recommend the best setup for ya.

Looking at lighting a 120“x60”x30” mixed reef tank. Will 8 pendants mounted about 8-10 inches above tank have enough coverage?


What if I flush mounted in ceiling about 30” above water surface with 35 degree reflector be enough coverage with 8 pendants?

Depending on what you're looking to do, 8 units above the tank about 10" should cover the 120x60 just fine.

If you're 30" above the water, you may need to add two more.

Two of the A500X with the Aquatic Life Hybrid will work very well for that system. If I'm in your shoes, either solution (2 A500X or 4 A360X) are good choices. I'd go with the A500X units if it's a flatter rockwork, or the 4 A360X if the rockwork is more jagged (highs and lows).

Let us know how else we can help

Thinking about this some more. How would you feel about three A500X vs four A360X for an NSA, jagged type scape with some highs, lows, and caves? Mixed reef but with a goal of becoming SPS heavy on the upper to mid sections. Would the three A500X provide decent coverage to match the four A360X? Or would that be overkill and a job best suited for multiple A360X in your opinion? Or- four A360X with the narrow reflector? Both options would be in conjunction with the Aquatic Life 48" T5 Hybrid fixture.

The Aquatic Life Hybrid is going to provide fill light for even the most dramatic scapes.

After that, your main concern should be how much intensity you're looking for. I personally always err on the side of too much light that I turn down, opposed to too little, so in your situation that would be the 3x A500X option.

I agree, I would rather have too much light and run the lights at a lower power than not enough. Any ideas or data yet for your recommended mounting height for the A500x?

It depends on your desired intensity and reflector choice - but roughly, the A500X with a bare lens (110 degree beam angle) will mount well between 6" and 12". The 55 degree reflector allows you to work well between 8" and 18". The 35 degree reflector allows for 12-30" mounting height.

Again, these all depend on your desired intensity at a certain tank depth. Lower mounting height will result in more intense lighting but less overall spread.

I was aiming for approximately 8" mounting height. I am limited in overhead space where the tank is located, with only about 12-16" from the top of the tank to ceiling (basement with uneven, drywall-ed ceilings). If I go with the A500X's I would have to figure out a way to mount them separately as they don't fit in the current Kessil light brackets for the T5 hybrid.

Overall I'm still pretty torn between the A500x's and the A360X's. I would really like the extra power options with the A500X's but mounting options in the hybrid may limit me to the A360X's.

Hello @Kessil
I have another thread on this topic, but would value your opinion here also.

I am currently setting up a 84"x30"x24"(deep) ~270g reef. I plan to keep a mixed reef, but heavy LPS and some SPS. I currently have a 36" and 48" AquaticLife Hybrid t5 fixtures that will sit above the tank. The plan is to mount the lights between 20" to 24" above the tank within the canopy. I can mount lower if it helps....

My current 75g reef (everything will transfer to the 270g) uses two xr15 pro G3 and the 36" Aqu. Life T5 fixture.

My thoughts for the new tank is to start with two a500x (use 55deg lens) lights combined with the Aqu. Life T5 fixtures. IF needed I could add the old xr15 pros at the ends of the tank to fill in dead spots if needed.

What is your opinion on this setup at the height of the light fixtures above the tank?

I appreciate any feedback, happy reefing!

The standard "universal" brackets for the Aquatic Life Hybrid should work with the A500X units for your mounting. I haven't tried it myself, but they hold the A360X units, and the screw lengths and dimensions are the same for the A360X and A500X.

At that mounting height, the A500X with either the 55 or 35 degree reflector is going to be your best bet. It provides the most versatile option, and will let you run the amount of light you need for now and for the future if you decide to go more SPS dominant.

That'd be great, I didn't realize the universal brackets would work as well. I was thinking they would need a version of the A360X circular bracket. Thanks!

@Kessil would 2 A360x’s work for 48 long 20 wide 30 deep mixed reef? What diffuser? Or with that depth do we need the A500x’s? Thanks
You're definitely at the outer edge of the workable range for the A360X units if you're using them over a 48" long and 30" deep. If I'm in your shoes, I'd either use 2 of the A500X units, or 3-4 of the A360X units.

@Kessil starting up a 36x36 tank it’s only 20” deep would the A500x paired with the t5 hybrid be a good fit?

Also can you clarify mounting with the universal bracket. I was under the impression that one of the circular brackets would be needed?

Are you talking about the NUVO 112? 36x36x20!
 

Have you ever had a reef tank with no sump and how did it go?
