IMHO, I would avoid Amazon like the plague, none of the companies that make the lights on Amazon are really directly related to the sale, Amazon is, so I have had, and have heard almost nothing but horror stories, of something WERE. Let's say, to go wrong with your light it's like going to the middle man to tell the weed guy ur bag was short. Good luck with all that..
That's another reason why I always recommend a company like migro or
HLG, I HA E HAD A COUplE ISSueS WITH PRODUCTS SHOWING up damaged, but one email and literally within minutes there was a brand new board in the mail no questions asked. (sry for the caps) two days later I had it in my hand. I learned the hard way cuzni went to Amazon first too now this is what 2000$ worth of Amazon lights look like hard at work
Do Amazon lights work?... Absolutely! Some very well..
Are they as efficient as they are advertised? Lol almost never you see how they all have fans and shit, even if the light itself is somewhat efficient, ur will def lose all efficiency making up for how much heat they put off ur ac is gonna work OVERTIME trying to deal with them.
ESPECIALLY IN A 2X4 ITS A RECIPE FOR DISASTER U WILL EASILY FRY YOUR PLANTS!
LASTLY... Do they ever properly cover the area they say they will in the write up?
The 1500's I got from Amazon were advertised as covering a 70+" x 70+" area.
They didn't even properly light up a 2x2' area.
Any "led" advertised in wattage is gonna be a disappointment. Ur looking to save money by drawing less Watts why would you go for a product that supposedly pulls the same wattage as an HID it completely defeats the whole purpose of switching to led might as well just throw another 600w hp cuz ur gonna be putting off just as much heat with those shitty leds.
Go for a proven reputable brand. Like
hlg,migro, or rapid led/growmau5. DNT be dumb like I was thinking ur "saving money" shopping on amazon
