That looks reallylose to what im looking for, TY! But both links are broken, first gives me nothing on chrome second gives a 404 from digikey. Do you have any more info on these drivers in order to google/octopart search?

It has fairly high max amp output, since im leaving this in the hands of my slightly all over the place growbuddy i need it to be quite idiot proof. Thx anyways though :)

What your talking about, "led watts" are really just a marketing ploy of the past which is one of the reason you believe you lose yield compared to hps. This was all true until about 5-6 years ago when everybody just started to use real watts/what the light actually draws. My growbuddy was the...

Uvb diodes have very low max amps and the ones in looking at are china made. So if i lose a string (due to my shitty solder work or my buddys clumsiness or whatever) ill either break something in the second string and/or burn the shit out of the cannopy due to double output and low hanging...

Hey guys! Most of the times i know my led drivers but this is somewhat especial: Im looking for low amps (less than 200mA) high voltage (if possible about 100V) and if possible also dimmable. Hoping to set up some UVB for a friend and these diodes taje very low amps. Anyone have know aby good...

Bxeb gen 3 comes in 2 versions: slim and original. Slim are 590mm where as original version is 560mm. Personally i dont really like the slims, they are quite thin and flimsy. Also the connectors where somewhat problematic with 1mm wire, they are made for 0.75mm.

I like all and any testing. Migros approach is good, it gives you the end result of spread, watts and efficiency. However, he uses a tent type space for measuring mostly which might muddy data for a larger openspace with multiple fixures. In the end though, for that testing/growing youtube...

Chilled puts those crees in a lightsphere and the real numbers are quite a bite lower. All those numbers are from the spreadsheets that where based on datasheets. Which werent completely correct. The test reports are on on Chilleds webpage. And Cobkits here on the forum ran a lot of tests in his...

First of all, are you basing your calculations from alibaba numbers? This is most likely a misstake as most numbers of performance are inflated. Second: if you wanna do a classic Solar power installation with ac inverters and batteries youre kinda missing out on one thing: youre solar produces...

I think led-tech.de have these diodes and use them for their own strips. They made some ppf measurements which was kinda underwhelming. Back to the day job for me...

I think penetration as a concept is a bit of a growbro myth. In general: the more pointlike a light is the more it will throw light in every direction, which means inverse square law of light intensity: light levels decrease faster as you move away from the light. When loads of pointlike light...

I think you might be going about stuff the wrong way: if you dont have enough amps on your installation you can try to grow with less watts per area: use autos instead for a at least 20 hour cycle. My i built some lights for my buddys grow, was 100w for about 7 square foot so about 15w per. He...

To be honest it looks like you have things fairly under control : if it aint broke then why fix it. No matter what all the theory is you always need to start by looking at your plants. If theyre growing happily then your good. Sorry about getting you all riled up about blues and uv. I encourage...

So i was writing something previously then you hit me with leaf surface temps: 660 , not really. It is a very efficient wave length for the photosystem. Far red yes, it can raise leaf temps a bit since it isnt very photosyntheticly efficient: a lot of energy doesnt get converted to sugars and...

If youre adding more than say 20-25% 660 then i would just forget about the white and just focus on red to far red ratios. Have a look at 4000k and 5000k 80 cri spectrums: they contain 20% and 25% blue, a big serious spike and much stronger than the red you see in standard 3000k. So if there is...

Me too! You can see it as a slip up or an opportunity to see something new that we wouldnt ever have seen. The standard knowledge says that its the red/far red hormonal thing that makes night and day for the plant, something ive doubted being the end of the story. We now see uv outside of par...

I hope youll still see the grow thru as it has been somewhat different: higher ppfd, lots of uv etc. Its these cases when something goes wrong were you get to see new things and learn.

Hey as long as it works for you, we seem to agree that theres some ac power going to the driver thru the plug and timer. The idea of this being by design though, nah, thats not going to be it and i think its better not going there: people read this ages after when something isnt working and...
