Please post a link to where you can buy QB288 panels with LM561c S1's for $4-5/PC.
Thanks
I tried to get a quote from Meijiu last night for some QB800s with LM561c's.
She said they don't have any bare boards for sale with 561s. "Too old" she said.
The only thing Meijiu sells with lm561c's now is in the form of a kit with ballast and heatsink. Their prices on them are actually higher than LM301b/h per diode.
I was quoted right as 301s were being used mainly. Like 6-8months ago. So they may just not have them anymore.

Just placed my first order from Kingbrite the other day. Only took 2-3 days for them to get it sent out.

Now I'm looking at Meijiu due to all the recommendations here. I love their English: "The Magic grow lamp make plants enjoy warmly sunshine just outdoor." I wonder if these kinds of companies understand how bizarre their translations can be, and if they'd pay a bit to have native speakers fix them. I know a literate American English speaker who will work for merchandise. :)

Do shipping costs normally fluctuate a great deal or very often?
Shipping before the pandemic was honestly pretty much steady. It's being taken advantage of right now. Your best option is to ask multiple vendors for quotes on total cost including shipping. Also, use the walk away approach at higher rates and hope they drop them. For a box the size of boards, containing them, drivers, and kit supplies shouldn't ever be more than 40-50.
I had 15 144mm round pin sinks shipped for 80. It was a heavy box.

TOP! As in foTOP!

OP: if you go for the sidelit vertical approach youd do well in getting something with photored/far red as top lighting, afaik the photo red is what gives the plant an idea of which direcction to grow and could be a good way to get your plant to reach for the top and not only to the side.

Cunt examination had to have been someone playing a joke on them. Because that definitely is not in the English dictionary .

My boards are on the way, one got to LA the rest are on hold in Hong Kong. Says I will get them by Wednesday....we will see. I got the 220W Archibald boards, 4 @ $110 ea, Shipping was about $35-$40 for each one....stupid but now I see they are each shipped separately so that is why.
I'm curious if I can put fans on them and drive them higher...drivers are 240W drivers so I don't see why not. I'll post my findings when I get them unless somebody already knows??? All my lights currently have XLG series (Constant Power instead of Constant Current or Constant Voltage) so i am clueless on the others

Hi Bud
How do you like the Bava lights?
I was looking at 2 boards (2 x 120w) for my 2x4 tent.

These are Bava 240 watt I just got.

2700/4000k Lm301b with LG385nm and Osram 660/730nm. UV on/off and dimmer. Nice board.

They’re on for $185 plus shipping right now.

One of these would be perfect full cycle for your 2x4.

Yielded close to 750 grams under 3 of those bava board boards, bud pic is attached. This was my first run ever indoors. Used a old 240 quantum board to fill out the 4x8.

That's what I like to hear!
Tempted to pull the plug on 2 of them single 120w ones for my 2x4 tent. Look quite neat with the dimmer and driver not just dangling about.
The Alibaba Bava dude is emailing me a price tomorrow with shipping
Cheers

Honestly I was very impressed with the build quality and the packaging, top notch and everything came assembled so plug and play. They are going to quote you like $80-$100 for 120 Watt or $160-$180 for a 240 watt. I got them for $160 and later the price was reduced for me to $140 but that because of my situation. Being in Pakistan leaves with me very little buying power. Tell Alwen that a friend from Pakistan referred you.
