Alibaba - 240w QB Samsung Lm301b 288 3500k 660

[ORGANinc.]

Quick open box of Shenzhen Yuanhui LED limited's 240W QB 

Quick connect and plug and play features, leads me to believe these units are waterproof to some degree.

Dimmer included, Speedy delivery and great service and feedback throughout delivery process.

Included - Meanwell 240w driver 

The lamp is super light weight and still has a effective heatsink acting as it base. (screws and mounting made for driver on top of the light, but obviously don't do that) without the fan, the light was running around 45% and I could not feel any heat emitting, will update how the light distributes heat in my current grow, but seems to be doing the job more so now with the fan on above. 

Comes with mental string clippy hanger things, not my favorite but they will work for now.

Price R1408 each, Shipping, somewhere around 700/800. Customs for 2 boards was around 700 (ask for a discount on the invoice for customs)(and say for personal use)

Very happy with the purchase, light works perfectly and super easy to use.

Look to be half inch fins sprayed black, very very light weight. Does the job, but obviously would not be as effective as heavier thicker heatsinks. But Ill be sure to treat them right. 

Will post an image when i'm home.

none of my qbs have heatsinks, and i can touch them all for as long as i want... so i rate those should be good enough 

[Prom]

Sexy price... 

[Marzcanna]

They got a few products on alibaba with a min order of 1 piece. Definitely a good buy especially if @ORGANinc.Confirms the quality to be worth it 

[Nope]

Those 320W boards look sweet!

Ya they look well, I’d just worry about heat dissipation with 3 boards so close together. But I just thinking, can’t say for certain

I'm a complete moron when it comes to electronics. Ashamedly, I'll even admit that my lady had to set up the new tv and surround sound a few months back. LOL!

You don't know if they perhaps accept BTC?

China and BTC are enemies aren’t they the reason for its recent crash? Read that some still do trade in BTC but new legislation has made it more difficult to do so which makes it unlikely

The China BTC thing is old FUD, but you are correct. They are trying to push their slaves(people) into using a digital Yuan which has pretty much the opposite core values of BTC. I'm sure there are some people who would accept it still.
