Kessil LED spectrum?

[Lacktaters]

I'm curious about the makeup of the new Kessil 160we and 360we "tuna blue" pendants. They call it a "proprietary blend of UV light" while almost all the other manufacturers provide the exact breakdown of the diodes included in their fixtures.

 

[Lacktaters]

For example Ecotech gives us this information about their XR30wG3 Radion:

Cool White: 8 Cree XT-E (40W)
Deep Blue: 6 Osram Oslon Square (24W)
Blue: 8 Cree XP-E (24W)
Green: 4 Cree XP-E Green (14W)
Hyper Red: 4 Osram Oslon SSL (12W)
Indigo: 4 SemiLEDs (10W)
UV: 4 SemiLEDs (10W)

and AI gives us this information about their Hydra 52:

16 - Cree XT-E Cool White (> 70 CRI)
4 - OSRAM OSLON Deep Red
4 - XP-E Green
12 - Cree XT-E Royal Blue
8 - OSRAM OSLON Very Deep Blue
4 - SemiLED 415nm Violet
4 - Edison Opto 400nm UV

Why does Kessil treat this as privileged information and not share it with prospective buyers?

Because Kessil invests heavily in their R&D and they design and build their own clusters. If they published that kind of info, every Chinese LED company would be knocking them off. At the end of the day, i don't think too many people care what's in Kessil's super sauce. The Kessils work great and that is what most people really care about as opposed to caring about the proprietary makeup of their clusters. Personally, I don't blame Kessil for wanting to keep that stuff under wraps. Their lights are unique and unlike most other lights on the market. If I were a company like Kessil, I certainly wouldn't want to give overseas companies let alone anybody else the recipe to my success only to find it being knocked off at a fraction of the price from a company or country that has no laws against stealing other companies intellectual property.. Let alone brand name. There is a reason why almost all the worlds counterfeit products originate from China.. It's the wild west out there.

Also keep in mind that unlike the other brand fixtures you mention that use off the shelf sized and spectrum diodes, the Kessils are truly proprietary. As I said, Kessil builds their own clusters using micro sized diodes. If I am not mistaken, Kessil actually manufacturers their own diodes as well. As such, you are kind of comparing apples to tomatoes as far as lighting design and implementation goes. They both produce lights but their approach and form factor are completely different.

the old 350 had:
390 - 2
430 - 4
460 - 14
470 - 11
CW - 11

I can not link but put the following string in a google image search:

It shows up as the first image for me but you may need to scroll

Thanks for sharing. I'm wondering if the "improvements" for the E model include an increase in the Violet and UV end of the spectrum or simply more efficient diodes. I've heard the power supplies for the E model is smaller, so I'm assuming they are more efficient.

Is this the image?

I understand that Kessil invests heavily in R&D as I'm sure most companies do when attempting to produce quality LED light fixtures. I also understand that comparing Kessil's pendants to backwards compatible fixtures like those made by Ecotech and AI would be "apples to tomatoes." If you bought a Kessil 350w, that is exactly what you'll have for the life of the fixture. If you bought an AI Sol Blue or Gen1 Radion years ago, you could upgrade it to the AI Hydra 52 or Gen3 Radion Pro. I'm not trying to bash them here, because I agree with you that Kessil makes a very high quality LED pendant. I'm also in agreement that Kessil's LED pendants work. They grow coral, and their tight proprietary LED clusters and optics produce a shimmer that can't be matched. As someone in the market for a few Kessil pendants, I would just like to know a little more about the fixtures on which I'm about to dump $1200.

It's easy to find images of the chip running besides the above post and your eyes can see the basic makeup of a white, and several blue/violets. Your eye may not be able to nail the specific nanometer but you get the idea

I don't buy it.. It would be a cakewalk to "Reverse engineer" a Kessil for any company w/ a $1000 spectrophotometer..
One the same line where is the PAR data??

The "mystery" is strictly for mystery.
Personally I find it annoying..
This goes double for their freshwater version..

Running Kessil intensity based on par is not advised from what I understand, being that they burn things much easier than other LEDs on the market, likely due to the 390 nm UV diodes you're turning up when you increase that white channel.

Which you might be able to figure out yourself if you knew diode type and PAR


so you guess w/ limited knowledge or just others hit and miss?

 

[Bpb]

That doesnt really make sense.

Yes...Most reefers function on the guess & check system with regards to lighting. Most of us know PAR meters are helpful, but they're not the final word. I'd also venture to speculate only a tiny minuscule portion of reefers actually have or even use a PAR meter at all.

Besides...Would you really just go off of what the website says when setting up your lights? Those numbers are arbitrary. They often dont state whether the measurements are taken in water or in air. Your rock work will change that as well, temperature, and hanging height. There are too many variables. If you're going from MH or T5HO to Kessil, but are relying on what you may find online for the LED par values...that would be pointless, since you wont have that information for your current lights, so what are you trying to match? If you DO have a par meter and are switching to Kessil...Why do you need the manufacturer to tell you what they got, when you will likely test yourself and know what your true par map is. Point is...It doesnt matter if an led seller states their estimated par values, as those numbers are fairly useless anyway.

so you think it is harmful for Kessil to provide little information on their lights?

In which case nobody should publish any info.

Or pointless?

Or harmless?

in which case all should but it doesn't matter..

at least you didn't use the "keep it secret" from the Chinese.......

 

[Bpb]

Yes to both. Harmless and pointless. There's enough user data out there to know to start low and expect sharp shadowing

 

[Bpb]

And I agree it can be easily reverse engineered. Pretty much already has to a certain extent

Hi. New here. Basically I have 75 gallon reef tank. Mostly soft and lps with some sps. I use 2 Kessil 160we. I want to add t5 ho 54 watt x 2. What brand and type t5 fixture or retrofit does anyone recommend?
