Hello everyone, I have 2 cob cree cxa3050 3500k leds available. Could I use them for a grow 60cm x 60cm (2'x2 ') with good results even in bloom? I would use 2 drivers @ 1500mA about 50wx 2.

Thank you!

100W for 4 SF is less than you should have for flower, im guessing those cobs are older so id shoot for 40W/SF with those

Thank you guys!
I think I will use the 3050 for a micro Growing and I will assemble a lamp with more recent cob!

I'm interested in cheap LEDs but I guarantee a decent performance. I closed a couple of crops with a lamp formed by 5 LEDs of 50w cob dob taken from AliExpress and the yield was decent. I would however point to something that has a greater efficiency .Our advice is welcome! Ah ... happy holidays guys.
