Can you get At least a lb in a 4x4 with these lights?

Lol I’m not sure what to buy I would just like to be able to get at least a lb that’s all lol. I’m kind of new to all these lights I used to grow n a speaker box with cfls n get a 1/2oz n be happy. Years ago
 
I have a 4x4x6.5 tent and would like to know if it’s possible to get at least a lb each cycle from this lights. I was going to buy 2. 4 -6 Plants would be in soil in 5gal pots. I thought about going HPS but worried about the heat

1800 Watt X6 Cob Led Grow Light Full Spectrum Led Plant Light with Daisy Chain, Temperature and Humidity Monitor, Hanging Hook, Adjustable Rope https://www.amazon.com/dp/B07V9V6M92/ref=cm_sw_r_cp_api_i_STekFbCKP5K3E
I use 4 1800 hollandstar cob leds in my 4x8 and I get about the same results as my hps lights I ran before just way cheaper. Way less heat.. also had my lights at 24inches from the top and had some light bleaching so I looked up the specs and they say to put it at 26 inches from the top. They are adjusting just fine now growing really fast. Great lights my 3rd grow with theses lights.

How many grows do you have under your belt using higher power lighting?
 
Yeah all the top cmh brands perform within 5% of eachother.... Ive ran both Ushio and Philips bulbs... they are all great. Just gotta avoid running shit like vivosun or ipower.
Actually when i first bought my cmh i ran the vivosun 3100k bulb and thought it did just fine. Their bulbs can be very inconsistent and thats why id say they are not worth using. The 4200k ipower bulb i use for veg alongside another cheaper canadian brand and they do great. Now i do flower with sunmasters and ushios 3100k and finish with illuminar 10 000k and only keep the ipower and vivosun 3100ks as backup.
