Best Bloom LED for 5'x5' 2022?

I'd give the 720s another shot with what you've learned about temps/vpd, I'm sure you can beat your old yields with it.

I believe so too.. Also it being summer real soon here it wouldn't hurt. I've got a $6,000 budget for lights so I'm thinking about going with the HLG Diablo lights so far.. I want exclusively bloom lights that are LED.

Anyone looked into these?

Phoenix 680W

Spectrum King’s Phoenix 680W is the new LED standard for 1:1 1000W DE HPS replacements, using 36% less power while delivering the highest reliability in the industry. SK Cryo-Therm cooling technology enables an ultra slim form factor, allowing for maximum airflow and minimizing micro-climates...

I posted the same lights a few above yours. I own four SK600s. Three of them are six years old and one is five I think. I still use all of them. I can buy four of them for a couple hundred dollars less than the price of two of the SK600s when I bought them. I guess they are made in China now, if that matters to you.

I'm not super knowledgeable of specs and materials, so I don't know, but they seem really good for the price.

Damn that's what happens when you post a reply before reading to the end of the thread lol

How do you like the growth you get under the SK600's? Always have like the Spectrum King lights.
Have you ever flowered under HPS?

They were levels ahead of the game when they came out, but their spread is horrible compared to modern QBs and bars. They are still going strong though. I don't think a single diode has burned out on any of them.

Yeah, I ran DEs for the first year or so when I started growing. I couldn't deal with the heat or the electric costs, so invested a small fortune on the SK600s. My yields and quality kept improving, but I don't know how much of that was the lights or me just getting better. I bought a HLG 650r, but I'm still pretty loyal to Spectrum King because they've pushed up a lot of pretty colas for me over the years.

Im not a 100% but i believe i read somewhere on here that the sk phoenix light is a china make while the rest are US made. Also no diode count or any stuff re diode or bin or anything to support the efficiency claims.

You probably heard that from me. I asked them and took a screen shot. They said they have a patient on their diodes. There's a lot of mystery around them. I hear they're crazy lightweight, which is very refreshing after hanging and adjusting the SK600s. 1870 umol/s sounds pretty good for the price.

I watched that and all I really learned was the light is bight, lightweight and doesn't get hot. I like that dude though. He feels like an old friend at this point.
