No and no. Well… Unless you want like 900w of heat and 100w of photonsXD lmfao. See the problem with these chinese lights is they only there to make some cash. They dont give a shit what they are making. They get the cheapest cobs they can find. Slap them on a little heatsink, power it up with a shitty driver, attach an un needed fan to get rid of the excess heat caused by the uneffeciant cobs and little heatsink. Just to have it work for a grow or two before diodes or cobs start going out and you cant fix them because either 1) you dont have a clue about led lights. Or 2) you have to ship them far far away spending more cash to ship them so they can recieve the lights and hold them for a year before they get around to fixing them because they have soooooo many people sending in shitty broken lights for warranty so now youre out some cash and a light and you need to buy another light for the time being. Cough cough mars hydro… and they are one of the better companiesXD atleast they tell you they are ripping you off;)

Getian are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

We build our own cob lights to be more efficiant (600w photons, 400w heat.), have better spread, use less energy, learn how to fix and build lights, use good equipment instead of the cheapest you can find. Not to mention only needing like 600w of cobs to equal a w hps setup.

The w lights you are looking at wont even preform as good as a true 200w cfl or a good HO t5 setup. But will put out just as much if not more heat.

Lets face it. You want a good led? Youre gonna have to spend more then 100 bucks. Here i will show you some proper lights♡

Also rolerado… how you get 400w light with 2 cobs that are only roughly 100 each?XD

They work. Yes. The people on amazon buying them arnt people that have beautiful gardens with lots of knowledge on leds. They get them. Plug them in. And go review them. “They work great!” What you dont see is the review of them using the light for a few months. Any company i told you about arnt trying to sell you their product. They want you to build your own instead of supporting this garbage. They tell you real specs. They will fix your lights no problem. With no 2 year wait like most china led warrantys. There is only old dilemma that you are just now digging up. People grew out of bread board leds a while ago. People are even past cobs now. Quantum boards are the newest technology. All these shitty leds do work. I have some. They worked great. Got great yeilds. Dense nugs. But now they sitting there with burnt put diodes not even worth using anymore. I just try to get people to not go through using garbage and get right to the good shit. I wouldnt give my buddys garbage weed. Also wouldnt tell them to buy garbage equipmentXD Ps aliexpress sells all these garbage lights for dirt cheap… also think about how much these guys pay their sweatshop workers to put together these lights.

I have to say that I agree with @lotus710.

Being someone who purchased cheap blurple LEDs from Amazon, I can tell you they are not worth it. I used them once and get rid of them right away.

You should research “full spectrum”, “white light LED”, “COB”, and brands like Cree and Citizen. LEDs have come a very long way, but are still costly. However I strongly believe from personal experience that if you “Buy nice, not twice” they are absolutely a better value.

Here are some key points as to why I (and others) choose LED over HPS/MH:

• More efficient photon per watt/cost of electricity
• Less maintenance/longer lifespan (warranty for many brands)
• No heat to manage (more $ savings)
• Flatter dimensions = more headspace for canopy
• Many have dual spectrum (ideal for someone with one tent/space)

If you’re not going to purchase a DIY or prebuilt quality LED panel, go with traditional bulbs until you can afford it. After looking through many different options, the average cost for a “quality” LED Panel is about $2-$2.5 per watt/power (ie. 400W LED fixture = ~$800-$1,000). You should be aiming for 35-40 watts per square foot for LED.
