Kessil and Aqua Illumination Tested - Kessil gives of 7.5 Times as much UV as AI LED

[that Reef Guy]

Kessil and Aqua Illumination LED's were tested for UV using an Apogee UV Meter.

The Kessil gives of 7.5 Times as much UV as AI LED.

Kessil A160we LED spotlight review: the best gets even better

I wish there were more tests like this.

All I ever see are PAR Comparisons on LED Lights.

I forgot to post the Model Numbers.

Kessil A160 vs AI Hydra 52

d'oh! You beat me to it! I read this yesterday.

Any idea about the Kessil A360WE?

Don't know they didn't test it.

Jake Adams please test that as well as any other light that you may have and Post the Results on Reefbuilders.com

That would be great, thanks!
Reason I asked is because I have two A360 and they are growing my coral just fine and don't look that bad. I do wish that I had more control of the spectrum (particularly red) similar to the Radions, which I would have chose but money was an issue and I found these slightly used.
Need to have spending money for corals to put under the lights!! :thumb:

Just so you're aware, the difference between 2mW of UV and 15mW of UV is like comparing a speck of dust to another speck of dust. Both are so incredibly low that there is a zero percent chance of them having any effect on color or growth.

I was wondering if the difference was an amount that is biologically significant.

No, both numbers are completely and utterly insignificant.

How do you know this for certain?

How do you know this for certain?

Because I understand intensity. These intensities would not even be enough to activate the photosynthetic process, much less add anything to them. In addition, light decreases in intensity as an inverse square. If this reading was taken at, say, 6" away, if it's hung 8" over a 16" tall tank, the bottom of the tank would be down to microwatts​ of intensity.

Fair enough. I just wanted you to explain why you said it.

I'm interested in how these numbers compare to sunlight...

Also, wondering how accurate a UV meter is with LEDs, consider the PAR meter isn't accurate at all
