That second light with the Cree will put out close to twice the light per the amount of energy consumed as that cheap "300 watt" light. That second, more expensive light is also advertising a Mean Well power supply which is a top brand name that should last for +5 years.
The problem is with the lighting/tote geometry you'd be better off with two lights spaced apart particularly when they have 90 degree lenses. Or a light that has a rectangular geometry. That may influence your choice.
If you want cheap then something like this could provide better lighting geometry for totes. A cheap light like that with Epistar LEDs will still put out much less light per amount of energy consumed (in the ball park of 1.2 uMol/joule) compared to high end LED lights (closer to 2.4 uMol/joules).
Im using fox farm ocean forest , I just close the tent and let it get as high humidity as it wants, but I open the tent at least once a day and run a fan to give the plants a workout
The light I’m using is a viparspectra vt300, I was told by pretty much everyone that kratom doesn’t like led light but that’s what I’m using anyways , I just dim it down

No worries, dude. Happy to share my observations.
$100 each for the 300w version (~135w actual power draw). I've got 2 of them in a 30"x30" footprint tent. Pretty good for the money, I'd say. I think 2 600s or a single 1200 would be good too, though, in hindsight.
I can't compare against HPS, as I've never used them, but I'm happy with the growth these lights have provided.
I've got 3 very different strains growing in there right now, on my first grow. One is a northern lights type, one a big bud type, and the other an OG kush type. Flower structure/density are all exactly what I would expect from each of those types of genetics.
NL type has very very dense flowering sites with nice, swollen calyces. Medium-large calyces. Really dense bed of trichomes (see my last post - that's the NL type - dinafem industrial plant cbd auto, to be precise) all over the calyces and sugar leaves. Ridiculously sticky.
Big bug type (WorldOfSeeds Tonic Ryder) is, as should be expected, very fluffy with huge calyces that are very swollen. There's barely a surface on the entire plant that isn't just riddled with trichomes. Look up the strain. It really is as resinous as the breeder picture. Could probably stick to the ceiling if you stuck it there.
Kush type (Victory Seeds OG Kush auto) is pretty standard OG appearance. Smaller, medium-density flowers and lots of em. Good amount of resin, but not as ridiculous as the other two strains.
Happy as I am with my plants (especially considering it's my first real grow), I feel like I rushed the decision on the lights. I think I would've gotten much higher yields if I had gone with one of the samsung QBs. Live and learn. The viparspectras were cheaper and easier to procure. I probably won't trade up to a QB for the same tent, but given a do-over I would've gotten the QB instead.
Overall, for $200 and prime delivery (I live in AK and shipping is a nightmare without prime), I'm happy with em. I've learned many lessons over the course of this grow. As far as the lights/tent combo, I've learned that I can probably best utilize them by growing a single, untrained plant in that space with those lights. I'll go up in pot size (maybe 10 gallon), amend my soil more heavily, get a cover crop of clovers going before I plant my seedling, and devote all my resources to just letting one plant get as big as she wants to.
I think I've finally decided to go with ViparSpectra LEDs. They get good reviews on multiple websites. They also have a model that has adjustable intensity and is programmable. I'm hoping I can have two of those synchronized in a 2x4 grow tent. Not sure if that is the right amount of light, but it seems to be.
Viparspectra also make a 300w panel, that'd be much more appropriate for your setup
