Kessils and sps

I have, its been on a 75g SPS majority tank. It is definitely strong enough for all types of acropora including those maricultured. Mine resides roughly 10-12 inches from water level, peaks at 80% during the day.

On the extreme edges of the 48 inch length (6 inches) I only have montiporas and maxima clams at the bottom and they are growing rapidly. If you put a larger tabling acro at the edges, I'm sure there would be some shading issues.

I currently run my A360we at 90% over a shallow tanks and have gotten great results as far as coloration and PE goes. As far as growth it is ok, but not to be compared with MH,AI or radion. I believe thats something you should ask yourself to, are you looking for explosive growth? Some don't want to have to snip their corals every few months so its all a matter of preference IMO.

You guys know you're replying to people who posted over a year ago right?

Personally I think Kessils are some of the worst LED's in the hobby, like someone mentioned earlier (2004) they're dim and hazy. Their optic is tiny, somewhat opaque, and the way the diodes are packed together causes wave interference. They are literally a scientifically calculable lower quality fixture. I never got nice crisp colors from them, I did once I got rid of the Kessils and switched to Halos though.

Considering that some of the best tanks I have ever seen are lit primarily with Kessel 360 this statement isn't justified.
 
I think all the problems that the 360s had is mostly resolved with the AP700s. I expected to need T5, no way! My tank is flooded with light.

Wave interference? It's called shimmer. The A360s were shown by BRS to provide one of the most even light spreads. Use a PAR meter.

So many wrong. Please provide your reference sir. The light must be monochromatic. See below.

In 1801, Thomas Young successfully showed that light does produce a two-point source interference pattern. In order to produce such a pattern, monochromatic light must be used. Monochromatic light is light of a single color; by use of such light, the two sources will vibrate with the same frequency. It is also important that the two light waves be vibrating in phase with each other; that is, the crest of one wave must be produced at the same precise time as the crest of the second wave. (This is often referred to as coherent light.)

"So many wrong".... Oh the irony. I don't think you understand what monochromatic means in the Young experiment or how it's applied. Two diodes of the same color next to each other are monochromatic, and the optic is tiny and hazy. Kessil 350/360 are absolutely 100% equation-provable lower quality lights, my reference is 2 years of upper division physics including waves and optics.

Locals here joke about how bad they are, to each their own I guess but the science is inarguable.

Seems you're the only one to bring this up as an issue.

Because they pass through the same lens makes this a non issue. Please shows us the evidence that proves what your saying. I'm sure in your studies you had to provide reference. Of this in fact true I'm sure many people would be very interested in seeing it.

BRS did some pretty good testing on the Kessil AP700 in this video. Confirming its improved spread/coverage, spectrum, PAR, shimmer, proprietary UV/UVB mix, Kessil Logic (ensures appropriate spectrum for optimal growth/color not matter the spectrum you chose), and blues peak exactly matches Radion and the most successful/-popular ATI T5 bulbs. The PAR results even surprised BRS with its power and its large coverage with even numbers. The video confined what I and many others see that the AP700 is the best LED fixture right now.

How long has the AP700 been out, almost a year right? Anyone care to post pics of their SPS?

Unfortunately, almost all of the sps tanks that I've seen lit by Kessil have been underwhelming.

Don't bash me yet, I completely understand that there is more to SPS color than lighting. I ran a metal halide tank for years with crappy color.....

It's been out less than one year. However some of the best growth and color has been with Kessil 360s with T5s. Many will tell you and I have seen many outstanding corals under this combination. Two years ago when the 360s fist came out all the same questions and criticisms where brought up. Now 360 and T5 right now is top dog. The AP700 will prove with results, but it will take time. Corals don't grow over night.
