Hi all...i question on these two led lights, does more ir and uv lights mean it's better or should I stick with less? Please any comments will be helpful! Thanks to the 420 community!

Yea ive never went by the advertised watts iknow the actual draw is 300 probably with both switches on and I was planning on picking 3 of them up ..two for a 2x4 tent and one for a 3x3
I was thinking of getting 4 or 5 cob cxb3590 for a 2x4 and 3x3 tent whats your take on them?I think you should look at better lighting options than these ''cheap'' blurples/chinese box lights/mono diode caskets or whatever you wanna call them
They're no more efficient than HID, a lot less reliable and the fans inside them are loud AF.
In reality the small spectrum tweaks make close to no difference if the plants are saturated with light, you need much more IR or UV to see if it has an effect, it's just marketing...
I highly recommend going for either HID if you're on a budget, or for proper quality LED like Quantum Boards or high end COBs (you can get better and cheaper COBs than CXB3590 nowadays)
These will give you 50% more light per watt than the blurples (and HID) and they're 100% silent and don't break down or have diodes burning out / dimming down.
Like night and day
I'm lost when it comes to lights, I'm a outdoor grower just coming into indoor and am all just confused on lights I like hps and mh setup but don't like the heat problems or the electricity use
Well, if you get an LED of the same wattage as a high pressure sodium, the electrical usage will be roughly the same, differing only slightly and that because the amount of loss due to not being 100% efficient (nothing is, really) is likely going to vary just a bit from one electrical device to another. In other words, a 600-watt HPS will probably consume just over 600 watts - whereas two 300-watt LED panels will probably consume... just over 600 watts .
Heat, depending on your setup, could actually end up being more of a factor with LED. Consider the two aforementioned lighting setups. The 600-watt HPS will probably be in an air-cooled reflector and will almost certainly have a remote ballast. The air-cooled reflector gives you the option of cooling your light(s) on a completely separate ventilation run - air comes in, passes through the reflector, and goes out again without ever entering your grow room's "atmosphere," so to speak. It hasn't picked up any scent, so no need for a carbon filter on that ventilation run. Therefore, no backpressure added - meaning you might get by just fine with a cheaper fan, since you won't need to move air through an obstruction. The ballast, normally, would be placed outside of the grow space, so it's heat production isn't even counted. The two 300-watt LEDs... Just have internal fans cooling their components - no flanges to connect ducts. That means you must cool the lighting and cool / ventilate / sanitize the odor as one unit. And the LEDs' power supplies are internal - which means that, unless you want to "remote them" yourself (which, admittedly, isn't difficult), the heat those power supplies produce is getting dumped directly into your grow space.
LED grow lighting is kind of cool. And some of the newer stuff does have an efficiency edge. But we cannot really state that "LED is cooler and cheaper to run than HID," in the generic sense. Not having to replace bulbs regularly seems like a clear "win." But LED panels occasionally fail (or partially fail). Then you get to send the product off for repair or, if you can determine the exact problem and which components require replacement, request repair parts be shipped to you (and hope that they do so in a hurry ). With HID lighting, on the other hand, you'll probably end up with an aged - but still functional - bulb in a cupboard somewhere that you can swap in about 30 seconds. Or, if not, you might be able to pick one up locally. So I see that whole "no bulbs to replace" thing as being a potential benefit that depends on quality of the LED product's components (and of the labor which assembled them) and on the individual gardener's circumstances/situation.
I'm NOT saying that you shouldn't purchase an LED product. Just that - again, "in the generic sense" - a random LED product is not an automatic win over a random HID product. And, for that matter, vice versa.

So whats your take on cobs Cxb3590 ?
Great COBs, but they're obsolete
Hi Bweezy, IR and UV is helpful for growing, but not the more the better, if too much , it will also influence the grow with less quality or less yields.Hi all...i question on these two led lights, does more ir and uv lights mean it's better or should I stick with less?
