I also sort of started with cfl, not counting the 1000w hps grows decades before. They were fun because I could say I was growing my own. But despite not feeling hot they do give off a lot of heat for the light they produce. They don't have much penetration/ usable light.
For the above wattage in Quantum boards you are getting a hell of a lot of light. Especially when compared to CFL or cheap LED like Mars, or even the equivalent HPS.
Or you can build your own Cob array with something cheap but efficient like a citizen 1212 chip, 4 or 5 of them would light up a 2x3 real good and blow those CFLs out of the water when it comes to yield.

Cob's do they have the 1212 chip in them
I'll post another picture of my homemade fixture this evening I was wondering if I could replace my CFL bulbs with the COB bulbs

Yeah, citizen do a 1212 chip. think its a 36v chip. Check out cobkits.com or speak to him one here.
560w of CFL is 40w short of a 600hps( obviously) the efficiency of hps is better than CFL, the heat should be very little difference, provided you didn't have the thermometer in direct light when running the HPS. If you did then your picking up radiant heat from the IR light which gives a false reading on air temp.
My opinion would be that you may be saving a degree or 2 in heat using that amount of CFL but the loss in yield will be huge compared to HPS in the same environment.

I run Cobs these days, used to run 1800w of HPS. Before that about 200w of cfl in a different environment.

If you check out that Quantum board kit, they do a 260w kit which would out perform all those CFL and save you a bunch of heat. It would be more than enough light. The 135w kit would cover your space at a push but if your already running 500+w of CFL the 260w kit would be the better option.

With Cobs you have the world in your hand since you can build any size unit and these days do it at a reasonable cost.
For example
You could buy a meanwell driver 185h-c1050 for $45-$60
5x citizen clu048 1212s for about $13 each
5x 120mm heatsinks for $10 each

$160 dollars total.

You would need thermal paste/adhesive and some wire on top of that. Plus the prices I quoted are from the cheapest supplier I know which would mean some shipping and import tax. But The suppliers in the USA like Cobkits are fractionally dearer and possibly cheaper if your in the USA because of the lack of taxes and cheaper delivery. I quoted the figures above because I have them at hand.

Anyhow, those are my opinions on what could be used in your space. By no means am I saying CFL wont grow nice weed, because it will. Just options should you ever want to change for heat reasons or power consumptions and quality/yield.

Heat right now isn't really an option because they're actually in a cool environment and the heat from the lights helps thanks for all the information it's quite helpful

what LED would you recommend? One that could do it all with "reasonable" yield.

i like matrixS ones they were the first to have a programmable system (veggie/ flower/and UV )
ok this is a Maker not a retailer .........to get the current prices u have to write to them a email ( they are the ones that make it and sell to retailers for resale a much higher price)
u will pay shipping cost and import taxes (shipping for me was fedex ) they will sell u 1 light or 1000 lights alls they ask is not to post the price u got it for.....cutting out the middleman (i got 2 lights and 2 controllers back when they used them for the price of 1 light plus 50 bucks) ..........i made it back 3 times over in the first grow ....i honestly was not excepting the frost the UV got me so i raised the price per oz

to write to them just allow all scrpts on the page (no worries no bugs) a little pop will fallow u down i clicked on the kevin

What about the viparspectra lights?

to be honest

i do not like the wording or the price they are asking for ..........they do not tell u the drivers/ the number of fans are low to me (heat is the death of electronics so would want a over sized system to keep as cool as possible for longest life ) and they are running a 5w chip saying it has 100k hours (it could have 100k hours if was running in a room in the low 40s and under)

basically the light i am seeing is a generic copy of the G8 lights ....bad rip off of a proven design
https://www.ledgrowlightsdepot.com/products/g8-900

when u look at a place u should see info like that the g8led list or ledzeal

if u want a LED full specturm .........just look at the apollo LED on amazon ...........they worked for me well and several other ppl .....the cost of the light is recovered in the first grow everything else after for the next 3-5 years is profit
