CXA 3070 Microgrow help

Hey So I am looking at buying 3 cxa3070 3000k cob I want to purchase everything off Digikey as that would work the best for me. I have a solder gun I just need a bit of help with what to get as this is very confusing to me.

I have read through some of the LED cxa3070 thread but find myself becoming quite confused by all the electrical talk.

I do not have any of the equipment apart from a solder gun and some lead solder.

Would somebody please be able to tell me what I will need to purchase from digikey.co.nz

Any help is much appreciated

wire, IDEAL HOLDERS (so you don't have to solder directly onto the cobs, and let them be easily swapped for the next best available bin), driver(s) to power them, fans you plan to actively cool them, a PSU for the fans, and a heatsink, and id suggest a power switch to turn it off without having to plug or unplug without a power strip.

Youre probably not gonna be able to get everything from one place, just my guess.

what size space are you going to fit three of these in? you know about how many watts you are shooting for? hearing "micro" makes me assume one would be fine...

uh its not gonna be extremely micro, probably gonna be about 1.2metres wide 1.3-4 meters high havent decided yet.

What would be ideal driver fan and heatsink?

Yea I wanna be able to plug into normal plug

1.2 meters squared? What are the dimensions of the floor?

havent decided yet ideal space is about 1.2m x 90cm

Basically just wanna get lights before I sort out space I was thinking of doing a veg with one light and flower with other two seperately as I might not be able to have flowers at my place.

bump,

Please would someone tell me what to order I'm stuck as.

We need the full dimensions of the space you're trying to illuminate.

If you want to design your grow area around the lamp, you should one of the 200W 94% efficient HLG-C drivers, a cob type, and multiples of that cob per driver, then scale it up to the foot print you want.

From what it sounds like, you're looking in the range of 16sqft, right? So maybe 2-3x 200W drivers.

would the cxa3070 fit those drivers? I get so confused when drivers and lights and watts all pile together,

16sqft yes we will do that. How many cxa's can I fit on those drivers

Its pretty easy to sort out how much juice you need. Looking at the data sheet for the cxa370, you'll see there is a range that it will operate at, with higher and lower operating temps on either end of the spectrum. Ideally you would want to power them in the middle of that range.

Looking at the data sheet use ohm's law to determine the wattage (amps*volts=watts) then multiply the amount of them you are using to find your total wattage.

Don't go by this as its only an example
38.5*1.9=73.15watts
There are plenty of options as far a drivers go, and most of the meanwells have a bunch of adjustability. Once you figure out the wattage you need, narrow down your search results on digikey then check the datasheets to see the range of adjustment. Dimming would be a good feature to have if you plan on working around the lights when they are on.

I have never built one of these, so i can offer you no advice for active cooling or heatsinks. The single array i built is passively cooled which probably isnt an option for you.

Okay so with the driver what would a suitable amount of watts be, So can the light be powered at a range of different watts?

I Would be keen on getting the lights powered at 80w if that is quite a strong light and is fairly efficient

Thank you all for the help so far, life savers
