you can get that very same 300 wat led thru marshydro for 68 dollars with free shipping, would I buy a mars light again, nope, but of all the "mistakes" I made along the way, the cheapy chineese blurple light was not the worst, it does function and you can grow bud, but if your not too late, I would do what testiclees recomends and DIY yourself a cob, a single cxa3070 cob can be build now for right at 70 dollars , and that single cob will rock star over that amazon light, and if you could build 2 of those cobs you would be at where my light is now, come take a look at my current grow and see what 2 cobs can do,, then look at testiclees or others and see what a bigger realy good led panel can do, my friend is building a new cxb 4 cobs light for less than 300 bucks, and its going to put out close to 40,000 lumens , thats pretty equal to a 400 watter HID
