I'm intrigued by the Bridgelux EBgen2, but I am also looking at the CXM-22 though it will probably take me a couple of days to work out two implementations to chose from(cost analysis) but when I have done that I will return. I have never seen Bridgelux EBgen2 used before, do you have any...

I don't know about CO2, everyone has told me that I really have to dial in every other parameter before CO2 addition can work. I can't recall the name if the product but there is a UK produced cheap CO2 system for small grow tents, it is a canister which feels empty but contains CO2 and that is...

Since a while before I posted my last post I have had a cart ready at digikey which include the UVA LED start boards but I haven't managed to get that order done which is a good thing because I have re-thought my hole grow setup. Before I continue I want to ask what you think about Solacure -...

Hello again. [Sorry for the off-topic information later on about my situation, but I can't manage to write a text with selected parts of this post and other parts are important enough for me to post that it simply have to be like this] I have been working on the code that will in the end run...

Some error occurred when I was posting so 3 or 4 identical posts was made, they are since deleted but I have also edited the post a few times directly after posting, just FYI.

No not at all, if anything I appreciate your honest opinion(and I'm the kind of person who really do need to be told to slow down and be more patient sometimes) but my reasoning here is this: In any case I will need 2 seperate drivers for the UVA and UVB lights and the UVA LED+driver choice I...

Sorry for the number of long posts but this one contains some actual relevant values. I'm not sure how to put this together but I figured I'll post this while I think about it. The following info and pictures concerns the Migro 100 grow light(which uses more or less the same LED as I...

Yes that gave me a few important considerations but I have a couple of questions. I have bought a cheap LX-1010B Lux-meter: My grow light are using 2 * CXM-32-35-80-54-AC00-F2-3 and I run them in a way that estimated from the datasheet charts should be around 170W together(so 85W each), do...

I can really agree with that sentiment, it is the same with the nutrient side of things in that I was told to stick to the base nutrients and not use any additive until I have learned more about the basics and in case problems arise they will be harder to diagnose if I am using a lot of...

I have a plan, first of I want to tell you about my safety features. I will install a magnetic sensor(don't know the name but those that are often used for home-alarm systems where there are 2 peaces, one magnet and one receiver which senses if the magnet is close or not, perhaps a reed-switch)...

Thank you for all answers, sorry for being absent for so long. @Airwalker16 Good suggestion, I hit a brick wall when looking for around 30mA adjustable LED drivers, this has 30mA as it's minimum(31mA actually IIRC) which might work just fine. Although this suggestion sparked ideas that has now...

Hello. I've built a DIY COB LED grow light using two CXM-32-35-80-54-AC00-F2-3 and the driver I am using(HLG-320H-C2800A) is allowing me to adjust the constant current output between roughly 1400mA ~ 2800mA which estimated from the datasheet of the CXM-32 would for 2 connected in series result...

I have been looking at light sensor, this is a brand new idea of mine so I haven't yet thought it all through but for a kind of low cost you could perhaps use between 4 - 8 different sensors targeting wavelengths that combined would give values that could be used to calculate a PAR value that's...

Thanks for your replies, I would have made the worst choice possible otherwise I think. I will get a few of the low-output LED's and experiment to see how many I need to see good enough.

First I thought that if I knew the output from my COB LED then I might be able to calculate the PAR, but now I realize that this sensor appears to be simply a device that tells you how much of each color there are while saying nothing at all about the amount of light in those wavelengths, which...

Hello. I have been trying to find a way to measure PAR without a Quantum sensor, there are those whom say that you can use a LUX-meter and simply convert the measurement to PAR by multiplying it with some value, but the problem then is the spectrum of the lux-sensor. I have found a interesting...

Hello. I have built my own DIY COB grow light with 2 * CXM-32 COB LED's(I had a thread about it a while ago). In any case I now find my self needing green-only lights to use during the plants dark hours, 12 hours is a long time and I don't want to be limited to the 12 hours of light hours to...

I haven't read it yet but I will but the introduction of this document is very exciting: "Dependencies have been shown and conversion factors have been determined, which allow to estimate PPFD, YPFD and radiometric power density of white LED light according to the known illumination in lux. A...

Hello. I've found a thread(can't recall if it was on rollitup or not) in which a person was modifying a lux-meter to get it to reflect a PAR value, the thread was very long and in the end I was nothing but very confused. But my reasoning is that if I had a lux-meter and I knew the exact...

The obvious answer might be "try out different values and see what's fits best".
