They aren’t bad, but just not very efficient. They did pretty good tho. You can check out my old Journal here Noc's 2018 Grow Journal.
During the summer I had heat problems while using multiple Mars lights. That journal was when I didn’t have any hlg lights. You can get the pre-assembled hlg lights for pretty cheap. I use the hlg 65w ($100) and 100w($150). I’m still waiting to upgrade further.
