Spider Farmer SF2000 VS Phlizon CREE COB 3000W Someone Smarter Than Me About Lights

So I have a question for someone smarter than me. I am currently running 2 spider farmer sf2000 lights in my 4x3 grow room, and my good friend just gifted me a Phlizon PHGD-3000 LED COB light. I was looking at the PAR and PPFD values and it seems according to Phlizon, that the light I was gifted is alot more powerful than my two spider farmer lights. I'm wondering if one of you could explain to me whether or not I should switch to the phlizon light and get rid of my 2 spider farmer lights or if I should just stick with those 2. Here are links to the lights for extra info, also remember that I am running TWO SF2000'S! I know there are alot of other factors about these lights I didnt mention, and thats why I wanted opinions about this.

The Phlizon light may have a higher PPFD reading directly under the light, but look how low those numbers get in the corners of the 3'x3' area. If you use that light instead of the 2 SF-2000 in your space your perimeter light levels will likely be even lower than that. Have you painted the walls in your room, or do you have reflective material on the walls?

You should also consider the wattage draws of the lights. 630 watts for the older tech Phlizon and about 400 watts for the 2 SF-2000. The Spider Farmer lights also run at a higher efficacy level than the Phlizon light. They will generate a lot more photons for the amount of power they consume.

If I was in your situation, I would use what you've got. Have each light cover about 3'x2' of canopy (that's a good coverage area for each light in flower with no CO2 supplementation).

Lensed cobs: concentrate light to the middle poor coverage on sides.

Thank you both

Also, yes, I do have the walls painted. Do you think its stupid to use all 3 in the same area? Would that be overkill for a 4x3 space?

Most likely to overkill. If your new at leds 20w per square foot is ggreat. 12*30 is 360. Or one sf and the cob light, but youll have uneven hanging height and cannopy.

I have used the phlizon cobs in my grow for a couple years now and they work well they are definately more concentrated in the middle and produce a bit of heat too. They have no problem covering a 4x4 and maybe more but they should be a good distance from plants to make sure they don't burn you can see what they don't the tube or insta if you find me with the name: cannabisconcentration if you are interrested
As far as the sf I have no experience but know they use quality parts, I have heard they are not as big on quality control with little things like even spread of the waterproofing and stuff.

Having run one or two of each....hps,led,cob,qb,blurple....they all grow weed. Although I've settled (are old stoners ever settled??) on a combo of cobs and qbs...I do run an old blurple or hps at times for filler...... Since I've always got several plants at different stages, I can isolate one to a certain light. Shit, when ya system is just about totally automatic, at least it's someting to do!
Right now I have a mephisto strawberry nugget isolated under my oldest cheapest blurple just for shits and grins.
About power...old sayin'...only improvement to horsepower is more horsepower...puttin' it to the ground is the trick. If my circuit could handle the load, I'd run'em. When I move up in watts/sq/ft, nuggs seem fatter with less foliage. I think its the multiple light dispersion causes less leaf fight for their share. When I'm above 50w sq ft, things do hop ......

The Spider Farmer light is more up to date with no moving parts, no fans, no noise.

Bringing this back from the dead, Rocket Soul do you know if it's a good idea to remove the lenses on these cobs so the centers aren't as hot?

I was cleaning my grow room and found my old Phlizon cob, I was wondering what I can do with it.

Im not too familiar with philzon to make such advice, but can talk in generalites:
Lenses focus light but also generally "use" up light by not being 100% efficient. They can also trap heat close to the cob which increase temps and lower longevity.
Focusing light maybe a good idea or a bad idea depending on the space: if you dont have very reflective walls its better your light has to hit the walls. The walls would sort of act like a reflector; another type of optics.
not focusing light would give you a lower hanging height but youll generally have higher light levels since nothing is lost to optics.
But then theres the heat factor: both by bringing the light closer, more heat, and there maybe an effect of covering your light emitting surface with glass or plastic, making the light more agreeable with the plant (i have no evidence for that but seen a few growers getting results like this; bad plant growth and deficiencies until they tried with something covering the but im not too sure about it).
Warranty: may be void with any modification.
Being a pro experimentalist id probably try it if the considerations are covered; at least youll end up finding put what works in your context.

Edit: optics has been discussed plenty around here, this post have some links. One of them to a thread by @SupraSPL , a guy who laid out loads of the fundamentals and ground work for diy led, an oldtimer ledguru who posts rarely nowadays. Some of his threads are very good read.
