I could go through and quote where you groups mine and Aquariuses statements together and just bitch because we are trying to understand or gave a lil bad advice. but thats a waste of time. Nothing constructive at all. IF I could delete the account I would have.

To the fact that he HAD had to defend himself, its the internet. we can walk away, there is no defensiveness. if he responded to a request for data like that in science he would be gawked at lol. Just rethink before we press enter to contemplate what we say and weather or not its constructive. I was simply asking for data he stated he had collected, then green gets defensive lol. I cant show you that ramble ramble ramble!

I have watched greens and reals and quite a few others channels for a while now. you state u have studied the par outputs in vids too, but didnt provide comps or total data at all. So without others having that data is it any good? modern scientists would say no! Absent from contribution and helpfulness I was and it seems this may be the best way. to contribute this info needs to be clear concise and not fragmented over 40 threads that are up to 3 years old. You know if a thread is over 2 years old I consider it to be outdated? I was positing scenarios, aquas too, perhaps under the impression that situation analysis could provide larger insight into the knowledge base especially for new people. Any way thanks supra for everything man. Your the shit, your quantifiable research is awesome! and hopefully Ill read more from you and others like you who are willing to put ego aside and collect and analyze some data. I am not dumb. I do hypothesis testing and have ran countless amounts of data through many statistical programs for studies. I find science in analysis and comparison of data, not befuddled arguments of dataless mumbling... maybe we just don't speak the same language. I never did get my question answered though. you got the data you were talking about? not u of as data not some study on green light, I mean the umol output with lenses and reflectors you stated you tested. lol jk idgaf any more. in the name of science!

You have not watched my channel or read my threads...or even this one for that matter. If you had you wouldn't be saying I don't post my results and charts.
At this point you can search for my quantitative contributions. I suggest starting a few pages back in here then going to my threads(many in the sig for your convenience).

topic officially de-railed lol. I have done a mix of both yes. YOu said at one point no less then 200umols. on a vid of you new light. That i recall of the top of my head. this thread was about reflectors and their efficiency at one point lol. didnt see a in detail chart, thats what I was asking about initially. Like I earlier stated man, I wanted to gather all this data into one place and organize it for the newer peeps So you wouldnt have been asked as many repetitive questions.

once I get things built, I am going to look into a umol meter. compared to the angelina xw those reflectors are nothing. and the outside looks like a disco ball. super cheap R and D. Actually I just went to amazon and there are some cheap par meters. Not bad for R and D costs at all. I worked in corporate america for a while. :D thats shit I get excited about.

You can use a smart phone application to detect relative brightness for making comparisons. You could also make a crude light sensor using generic photocells.

http://www.amazon.com/Sensitive-Resistor-Photoresistor-Optoresistor-GM5539/dp/B00AQVYWA2/

They are basically photo resistors. You can make a voltage divider using a resistor and a photocell, and use an analog input on an arduino to get a reading. Then you can display it on something like a 7 segment display, or transmit it over serial interface to your computer. if you could calibrate it right, you arrange them on a PAR grid and take all the readings simultaneously. The arduino mega has 16 analog to digital inputs that can be read simultaneously in "real time".

I actually did buy some of those a few years ago and used one to implement a crude light sensor. Of course the numbers it produces are meaningless to anyone else.

my lenses have ring that goes over the lense and screws on to the reflector. Holds the lense in place. I'll post a pic in a little bit. I still haven't heard anything on the tests yet. So I don't have the lenses on right now. Also all their little things like that. They have patents on them.

The best one is the available one

for now ;D lol it would be really cool if someone had a 3d printer, then we could really cut into some design elements. the xw is totally doable on a 3d printer. thats way more then a light meter tho lol. Nice shout out on the diy light meter. btw.

Shoooshhhhhh, you

:lol:

It could be done though and would probably fit our needs better, faster, and cheaper. My only concern is whether or not the plastic emits toxic fumes, which wouldn't be worth the extra gain.

church, funny you should bring this up, just about to put an entry into my blog, dealing with this exact thing....

I have a LDR [light dependent resistor] with a fixed 10k ohm resistor. The problem is that these resistors output into AVC and then have to programmed back into lux, like you mentioned, but it is a Serious bitch!

I would recommend the Bh1750, the Arduino ide already has the library for it [1.6 at least] and it will directly output into lux on Serial readout......much easier way to go imho......

When I googled 3d printer AND aluminum reflector...All I got were these funky examples that were cut 1st, then laminated with aluminum.....

Then when I search generically for youtube videos on 3d printing and aluminum, there is a lot going on.....although I haven't uncovered the actual expenses....but the capability is certainly there....

It would seem like Aluminum Reflectors can be done on 3d, although I haven't seen a specific example yet, dealing with our topic......:peace:
