CRI test and Mcree weighted results

[Greengenes707]

Not only that I like to drink and party. Sometimes my drinking will fuck things up in addition to my senility.




It NIST that proposed to not use the sphere for LED measurement in favor of a radiospectrometer. It was NIST that proposed the Flux Intensity setup adopted by CIE.

I'm not the only one that bitches.

Luminous Intensity was once upon a time THE most measured LED characteristic. Why do they choose total flux? Here is an an image from an old OSRAM datasheet.

What is the problem with wanting the measurements needed? I will show you why you cannot get this data from the spreadsheet and or datasheet. Please be patient.




Thank you. I am working on just that in my spare time that is really non-existent. I do have a spectoradiometer that is has a NIST LED profile calibration.

I have 1750K, 2200K, 2700K, 3000K CCT CoBs. Do you have a preference?

So I will still wait for actual fixture measurements as I figured.

And why do you selectively take things out of context...it doesn't help your point, and digs you deeper and deeper. Sphere are quite accurate at what they do. As are GONIOMETERS that I also said, but you choose to leave out because they show how everything you just said is false. Sphere do their job perfectly...lighting distribution is not part of that job. But again if you would actually read or listen...Goniometers do.
And when they are within .5% of the sphere numbers...you don't have a leg to stand on. This is not opinion or white paper manipulation. Just simple end of the day real world measurements by valid and industry standard instruments.

Does anyone here work for a living? I go away for 2 hours and there's 30 more posts!?! Lol. Very interesting reading.

 

[Greengenes707]

Oh! That was a very old paper. I'm sure spheres are much more accurate today. My point was that a radiospectometer is the instrument for the job at hand. The job being measuring the number of photons at the canopy. My bitch is there is no way to certain flux intensity numbers from a datasheet. I would like to see the manufactures provide flux intensity numbers like they used to do. Also I strongly believe the spreadsheet you guys use is giving you inaccurate data due to the SPD normalized numbers. I think those numbers should be actual measured flux density from a radiospectrometer and not normalized. And multiplying radiometric values by lm/W gives useless numbers.

Then the real bugger is those that do not think the distance from the fixture to the canopy is subject the Inverse Square Law. That is crazy talk.
I'm okay with the sphere for lighting application, not horticulture. Just like the NIST guy said. I agree with him.

Dude, stop making things up in your head and read what has be typed to you if you choose to keep disputing things.
I don't use a spreadsheet. I use a sphere and goniometer on a competed fixture performed by a certified 3rd party. It just so happen, that mine and others data, validates many of the calculations done by people such as @alesh, and SDS and others that you dispute so unsoundly. And why again I ask you...where is you actual results and own research. You claim to be so advanced and smarter than anyone else, and have so many creations and accomplishments...How do you not have any actual fixture/chip/board data??

If you want to keep in your own world...then start your own thread and spew whatever you want. But please start presenting some solid information and research of your own that can validate your assertions.

Other wavelengths, like far-red and green, are not so important for metabolism but they are not benign- they shape plant processes in other ways that optimize light capture and adaptation. - Dr. Kevin Folta, The Guiding Force of Photons

Clearly, Mr Folta thinks green is important and valuable to plants, doesn't he?

 

[NoFucks2Give]

Clearly, Mr Folta thinks green is important and valuable to plants, doesn't he?

Yes, just not for photosynthesis which is the topic at issue here. Green they find can modulate cryptochromes. Folta and Colquhoun are doing amazing things with light mediated metabolic response. They know how to alter taste, flavor, aroma, and overall quality. They are way beyond balancing red and blue light recipes.

LOL - so why are you all on about giving them blue and red and not the full white spectrum, which is clearly superior according to your gurus? I mean seriously, we've been pointing out for days on end that its not "all about the photosynthesis"

 

[cdgmoney250]

Ffs still discussing green light against while they still don't get the difference between relatively and absolute.

Unless you want to practice recognizing all the classic fallacies... run, it's a trap.

How did your blurple LED run turn out?

 

[NoFucks2Give]

so why are you all on about giving them blue and red and not the full white spectrum,

You are a slow learner I guess. What did you not understand about "Some wavelengths impart valuable information to
the plant that promotes growth, development and photosynthetic capacity. Other wavelengths, like far-red and green, are not so important for metabolism"

That covers the whole white spectrum. The the two bands that work for photosynthesis and the in between that is commonly referred to as the green hole. Does that not cover the whole white spectrum?

Not so much gurus as world renowned and respected scientists.

Why are you having such a difficult time understanding this, it's a picture, you don't even have to read.

It almost if you think I give a fuck that you waste your money.

thread is all like

 

[wietefras]

If you find it necessary to measure total flux, do as you please I do not give a fuck. I prefer to use ""Partial LED Flux" as proposed by NIST and adopted by CIE 127.

Bullshit. You don't do that either.

You are just trying to find some bullshit to look less stupid. It's really only making matters worse if you don't even understand when people explain that you are wrong.

 

[wietefras]

How did your blurple LED run turn out?

Lol, yeah it's funny how cagey he is on that one. For good reason though.

I was hoping to have my mind blown by the more enlightened.

Here I am wasting ALL this green light energy on plants, yet my grows keep getting better and better. Just imagine how much better the secret spectrum would do!

Ha, ha, me too. Such a shame that it didn't really work as well as was foretold in the stories of legends

Ah well, we will just have to muddle along with our wasted greens. How will we manage?

It would help if you actually knew the purposes of the measuring devices you mention. Sounds like you go and find one someone hasn't mentioned yet and drop it into a post to look credible. Might work for your 'masses of followers' but people who understand that science can easily see through such snake oil.

Like seriously, you don't have the educational background to know anything about the science behind it so pretty much anything you say is bunk.

Plus you are a vendor peddling gear that's success is entirely dependent on the propagation of misinformation. Conflict of interest?

Oh and your grows suck. If there was an SPCA equivalent for plants, they would be camped outside your front door.

12 year grower? So what, I still have viable seeds from research I did back in the early 90s. Now that it is becoming legal and mainstream in the US, the rest of us where it has been legal in various capacities can now openly share our knowledge. Suffice to say, the US is significantly far behind in horticulture research.

Do you realize all you just did is vent pure feelings??? Not a single piece of evidence, support, or factual information?? Literally not a single bit of concrete anything in your statement. Please provide some if you wish to get angry and attempt to properuate falsities from behind a key board. Aka...libel
And you seriously don't know what a goniometer is??? Nor did I just bring it up. They have been around for decades. That's not my issue or does it unvalidate the completely valid and industry standard numbers it generates. Ya buddy...I'm the uneducated one.


You can hate me all you want for what ever made up reasons in your head. Spewing hurt feelings about how I am correct really isn't helping your case man. Please come prepared with actual data to debate with if you ever think a single word you say will ever make a difference.

i am at least as old as you..and sure us old guys and our keeping genetics going for decades are great and we ARE the best.. but ....

his grows ARE pretty good...[for a youngster]

Most valuable thread at the moment

Used to be atleast. Im appologizing to Rahz for troll feeding. @NoFucks2Give would you just please start a your own thread? If wietefras and greengenes promise to stop by from time to time and troll with you? The way you go about just make people think that you dont have a clue. And this i dont give a fuck attitude is obviously bogus: why would you be on other peoples threads basicly trawling for attention and arguing if you didnt give a fuck? You dont put in an effort to make your point of view understandable in anyway, and when people ask you in an honest way you basicly behave like a prick (slow learner?) Instead of trying to actually explain, on your own terms ib your own thread. You say you soooo much scientific background but your sure dont behave like one. Get your own thread. Start explaining your point of view from the beginning. Make a compelling case. Me, i promise to read it. Dont troll threads that have nothing to do with what ever it is that is bothering you.

Somebody started this thread with a purpose and it sure as hell isnt this. Sorry to Rahz again, i hope to hear more about the continuing spectrum tests your running. Unsubbing this, well at least for now

 

[NoFucks2Give]

And this i don't give a fuck attitude is obviously bogus:

That name was because I saw how newbies were treated like shit here. And truthfully I do not care what others think of me, I know I am not normal.

These guys I answer in that manner have been on m\y ass for weeks now. I actually received a "Well Liked" trophy from this site. I'm not a prick to everybody.

I'm used to the Facebook Groups thing. I'm not too familiar with this type of forum. I do go back and delete my nasty grams when the insults escalate. Like yesterday I deleted those aimed at Gangrene 707.

I will do a thread but under a different name.
