PAR Testing - Kessil A80 vs $30 Kingbo bulb

[Mike N]

PAR testing performed with Apogee MQ15 par meter.
Testing performed in air at 12" from light.
(Kessil Intensity = 100% / Color = 50%)

Kungbo spectrum is not that great. Missing at least one key chlorophyll A point.

Thanks for pointing that out.

Hmmmm

I see screws! Might be able to modify the diodes? :D

Yea could be an easy fix on spectrum?

Interesting, and thanks for sharing! I'm not familiar with the Apogee MQ15 - details?

Thank you Mike!!
Very good information. I've always wondered about this 38's.

(Wow that 80s a dog)

Nice piece of hardware :)

Yes it is. Property of local reef club.
Membership has its perks ;)

Is there a spectrum graph for Kungbo?
Can you please post a link to it?

I wonder then if the Kessil H80 has the same par values. I should test this with my seneye tonight..

Please post up. 12in in air is a really good median base line to judge a lamp imo.

It's how I do it at shows, lfs and home but with a lux meter.

You can find this on Amazon but I often wonder the credibility.

I'll be testing the Aquaknight LED ($80) tonight from the same height. Curious to see how it stacks up to the others here.

I found one on amazon. If you search amazon for this bulb you'll find it. Sorry on my phone so hard to grab the link right now. This is also of course, taking the manufacturer's word for it.

if the kessil is like the other kessils the par reader will not read it right and we all know that kessil is a very capable light

Good to know about the distance from source to sensor. I'll test at 12 inches in order to standardize. When I started doing light measurements back in the early 90's, I used a distance of 3.5" since most luminaires rested on the aquarium's top and this was the distance from source to water surface. Times have changed... Matt @BoomCorals - I'm testing the Kessil AP700 now. This will get involved when considering multiple spectral/intensity settings. Thanks again for your support!

That's why I wanted to test my H80, those numbers seem really really low.
