The most experience I've had with an LED is with a Mars hydro SP250 in a 2x4 tent.
I'll spare the details as it was a bit of a journey (Unless someone is interested) but last run I got 16oz and 5 grams.

Quite a huge result as I struggled to even get a 1lb in a 4x4 with a 600w HPS

Yah if I feed at 1.8 ec ill drop down until im feeding .5 ish ec the last week. it does hurt yield and quality especially in coco. I mean I've done it all and have enough reasonsto ensure I get the best quality bud. Currently running 6 rooms with 150ish plants each.

I've done two runs under just LED's. 1250 watts total. Samsung boards, LM301B and H, meanwell drivers. The first one was all mixed clones. I had Durban Poison by D.Passion, C'99 and Super Lemon Haze by Canuk, Blue cheese by Barney's and Sour Diesel by Blimburn. It didn't go well at all. The plants didn't get enough intensity and were super spindly. Except the sour diesel; it did pretty well. I tried another run with more sour diesel and it did real well despite 31C temps at the canopy. I really think it might come down to some varieties that do well under LEDs versus some that don't. At least in my grow. I'm running 1000 watts of LED with 1200 watts of HPS for my current run though; so I'm not 100% sold on LEDs yet. I love them for side lighting though. Have a few pics of a just cut Blimburn's Sour Diesel. I'm growing it again. The whole bud weighs 65 grams dry with the stalk still in it; so a two ounce top.

My best yeild with led was 23 ounces in a 3x3. That was 4 plants in rdwc and 600 wall watts.
Strain was Arcata Ghost from Cannaventure.
Lights were 400 w timber 4vl and 240w qb.
Vegged like 1 month. The hydro hype is real. Usually get around 14 ounces with soil as the only difference.

300+g dry buds & trim for bubble hash from two autoflowering plants with about 185w of 4000K QB. Not my highest yield, but very nice for the wattage and space (D32" x W35" x H39"). One day I'll go back to 600+ watt grows.

My best LED harvest is 865 grams under a 1000 watt light.

I had a couple low producing strains that brought my total down, this harvest I should be over 950 grams.

I am currently running HLG 600 rspec (630 W from the wall) in a 4.5 x 4.5 tent. Best yield so far is 1.8 g/W (1135g). I am hoping to break 2g/W with my current run (pictured below) with some high yielding cuts. Buds are definitely a bit frontier under led as long as you keep the distance from the light correct. I have had the best results at 30 in with this light.

I think I'm 3 cycles in with COB l.e.d. and from 4 disodo plants under 600 cob I got 825 or 850 iso, don't remember which. So about 30 oz. With a perfect grow I can't see going above 35 but I've never had a perfect grow so who knows.
