What yields can be expected from this type of light?

Hi guys, I wan to buy a powerful COB LED light with a glass lens to replace my DIY light fixture with.
I came across this COB CXB3590 light. On paper it looks great and the price is the lowest I could find on the internet. It is within my budget and I will probably buy two of these - one 5000K for vegging and one 3500K for flowering. But before I pace an order, I would like to ask you guys: does anyone have experience with these CXB3590 lights? What yields should be expected from them? Can I do 2 grams per Watt with these?
Thanks!

Those lights are 50 watts actual draw each. I'd think you'd be lucky to get 1 gram per watt. With 100 watts that's about 3.5 ounces. If you flowered with one light you're down to 1.75 ounces. If you are growing in one space I'd recommend spending that $200 on a better single full cycle light. How much grow space are you looking to cover?

This kit is a bit more but it will have a very efficient driver with seven year warranty and those QBs are going to give you a lot more GPW.

If you want to stick with COBs give this one a shot, better kit all around.

Those HLG quantum boards are hard to beat....you may pay a little more for them....but you are getting a quality light with quality components....IMO

@buyyouabeer unfortunately, I cannot afford the lights from your links. I am limited to around $200.

I did a research and it turned out that that the CXB3590 LED chip that I want to buy is the same that is used in the popular "Optic 1" grow lights.
This guy claims that the 54 Watt Optic 1 can yield around 2 grams per Watt:

You originally said you wanted to use one light for veg and one for flower. 50w of light is going to cover a tiny area. That's enough for about 1 square ft, maybe a little more if it's actually a quality light.

Guys, please let me know if this HLG board is any good???
It is under $200 and I am tempted to buy it.
Is it any better than the COB light from my first post?

you can go to HLG website and order a 4 pack of quantum boards for just $130. then get a driver for around $60. you'd have to wire yourself, but i think its pretty simple. that will cover 2x4 i think

ahh, yes I see the "4 Pieces" now. Then the driver, and have to make a frame i assume?

yeah....on the same page, they should have driver suggestions. i got 2 240watt mean well drivers, one for each set of boards. i added a dimmer knob too. i used aluminum siding i got from Lowe's as the frame. some drilling and cutting is involved, but its pretty minimal. and let me add, that i had no idea how to do any of this before hand...but with some proper guidance on here, i was able to put it together quite easily. folks on this site are more than happy to help.
