Wrong. I have 2 on a 59" tank, 8 inches above, almost no spillover. 1 ap700 is better then 2 360s almost always

Thats because your tank is nearly 5 ft long.

His is 2 ft long. At 7" he is undoubtedly going to have a ton of spillover.

I have mine 8" on a 2ft with not a lot of spill over

Thanks guys I'll look into the AP700 as well!

It's less then 6" difference per light. Lower it to 6" and he will have no spillover.

I run A360s over my 75g and am doing it again on the 150g build; I wont use the AP700 because the modules are at a fixed distance where as I can arrange the A360s in any fashion I want to. They (AP700) offer no better light in regard to the needs of the coral over an A360. While the light may work well for you, on a 24" long tank the A360s are a better option because of the mounting flexibility alone. For what it's worth, there is no situation where I'd take the AP700 over the A360.

Define "not a lot". Would that be because you have yours mounted in a hood?


"36"x 24" at 7" above water level"
Sounds to me like there would be a fair amount of spillover on a 24" tank .. at 8" even more ..no?

 

[muz_z]

I can actually see I very minimal amount of spill due to the hood
I will grab a pic for you to see
As mentioned above did he lowered a little more he would have next to none

It would be interesting to see your hood, for sure. Please post it as I am sure others would like to see it as well as myself. I have been playing with the idea of mounting mine in a fixture that combines t5's.

I would say why you dont see much spillover is because you have yours installed inside a hood. Its the only logical explanation.

The difference in penetrating light to the bottom is night and day. On my 22 deep tank the same par at top resulted in over 50% less par on the 360s then the ap700s.

This is where the N comes into play.

 

[ComforablyNumb]

The difference is you are stuck with the distance between pucks on the ap700.
No such problem with 2 360's.

 

[WLachnit]

How much better does the N penetrate than the W?

Except that it doesn't come close to coverage width wise. Way too narrow.

That's the beauty of the individual form factor. They can be spaced and aimed anyway one desires.

The 2x360s is not equivalent to what you get from a single AP700 -- not in spectrum, not in intensity and not in coverage. A 4' tank lit with an AP700 looks great and if you space 2x360s out further, they look like crap because you end up with a shadow in the middle of your tank.

Not dissin' the 360s, but let's not get confused about how they compare to an AP700

Didnt say they did. What I said was you would have no means to point the lights individually as you can with 2 360's.

Thing is ..his tank is 2 ft. He's not going to have much shadow with either light.

Here's a 4 ft tank lit with only 2 360's (mine)

Do you see a shadow in the middle?

Neither do I .. The middle is where my most light loving corals live. (stylo sps in my case)

 

[M4rtin]

What about 36L x 20h x 20w tank ?
What would you recommend ?

 

[JustAClownFish]

Lol there's a guy on this forum claiming his corals are dying due to his FIVE Kessil lights. FIVE. First, he said he bumped them up and then they bleached but now after he measured PAR with some cheap *** PAR meter he concluded that it must be too little light.Sorry but every time I see successful Kessil tanks, which look incredibly stunning, I have to think about that dude. He told me has been in the hobby for 20 years, implying that I don't know what I'm talking about, yet he was the one offering to pay someone to help him...lmfao

Everything I see in that tank is low light. Edges on a 4ft will be very low par.
