DON'T TELL ME YOU THREW MONEY INTO THESE PANELS!
Going from HPS to LED. Worth it?

cxa3590 for veg buddy.
i have the 3590cxb 3000k for flower.

I used panels prior to switching to COBs. And there is a HUGE difference. Panels cannot hang with COBs. Your boy, Yoda, uses panels.

I made this point earlier about single point light sources vs multiple diode light sources.All goes back to the law of inverse squares , cobs lack initial value so penetration is much less, a single point light source with a big initial value will be able to be placed higher than multiple sources with a lesser value, it's just physics
Great info on hps and light

When did you buy your CXB chip, and how many plants were you growing? How high was it from the plant? Reflector or lens? What amperage? Because you should definitely increase your amperage. You still get efficiency.

I dont give a fk if my boy uses panels. im just happy i wasnt sucked into the led hype.
about a year ago. already used it for 3 grows. all 3 had issues. so i can't be all 100% yet. not till this 4th one completed.
here's the first op. with the 400w cxb3590 3000k. quality is top A. density was good, but as you can see in the picture, i was looking for the buds to be more fatter.. still wasn't what i was looking for. i think i had 3 plants in here.

That grow log is over 2 years old...

Increase your amperage. I'll bet that'll work fine. How long did you let it go for? Did you wait for the swell? If I can yield 3-4 ounces of fat, dense nugs with "450w" (206w) Chinese LED panels that had great penetration with only 3 weeks in veg from seed, I know I can do better with these COBs.

lol i am thinking of using these ford Fiesta cob headlights what Yo all think lol you think i will get nice big buds like this Cob grow

Yeah, but do you use COBs? If so, in what kind of setup? That is my question.

4x cxa2590 with some cree 5w panels to cover a 4x4 , not gonna replace lights that are still working fine, no blurple in the room only white/red.

What color, voltage, amperage?

5k with red supplementation, 1050ma

I seriously think it might be your color and amperage. Dude, I wouldn't be contesting you if I wasn't convinced. I think you need to run it at a higher amperage, and change the spectrum. Like, 70-80w per light, and in a white-er spectrum.
Reds don't penetrate. That's why we use red flashlights for checking maps during deployment.

This runs about 150 watts for 4 of them push them any harder and I will lose a lot of what makes them good.

I don't think you will. I think it will put your PPFD where it needs to be, give it more penetrating strength, and it'll still be below the power consumption of HID systems. I'll be running only 274w for 3 at full power.
Watt for watt, right there, that tells you why our expectations and results are differing. You're using only 150w for 4 lights. I'm using about that using two lights.

My leds are older tech this is as hard as they should be pushed without a full upgrade, which means new heat sinks, new diodes , new driver , basically I need to make a new led when I feel this one is done.

You could have grown all that with 2x 600w hps or 2x 1000w hps for sure, you got jipped look how close those cobs are bet those lights can barely cover a 3x3 and cost probably 800-1000$ each.
