I can't see any type of deals right now on Alibaba for their Chinese sale . Guess we'll have to wait for OUR black friday for good deals?
These things are dirt cheap already. $120 per 240 watt board. How much cheaper do you want? Buy 6, hang em over a 4x8, pull 4 plates, make 12k off 1k shipped. Waiting to save pennies is gonna cost you thousands.I can't see any type of deals right now on Alibaba for their Chinese sale . Guess we'll have to wait for OUR black friday for good deals?

correct, maybe i'm trying to save too much. you brought me back to light! :P
Been using kingbrite qbs for 2 years now.
Started with 240w . Slowly converting to 480w.
All work and still being used.
Saved thousands compared to hlg or sf
Only flaw IMO would be shipping time.
Here's my bloom room.
UV & IR diodes in the boards is not wise, you have just lowered the boards lifespan by 50% if not 70%
Why do you say this? Are you talking about having all of them on the same driver? Or just in general on the same board?
The main issue as I understand it is that the uv/ir leds have half the lifespan of the white light leds and their failure can make the whole board inoperable, so the lifespan of the board is only as long as its weakest leds. This and the fact that the higher price for those options make them a worse value (compared to other manufacturers) than the more basic boards being offered.The UV / IR discussion has been done throughout this thread. IMO, the consensus is quality UV LEDs are very expensive, so much so there is no way anyone is using them on the lights we are talking about here. The IR consensus seems to be they help, but you should have a switch to turn them on/off during specific times of your grow. There was also some discussion about UV/IR LEDs reducing the overall efficiency of the light / driver over time. I went with supplemental IR lights I can control separately.

that makes more sense but honestly UV diodes are garbage at this point, they are never detectable by meters than can detect uv light when tests are done on LED grow lights with UV diodes in em & they are uva not uvb, as uvb diodes are crazy stupid expensive & are pretty much garbage too. So why would anyone waste diode space on a board on em to begin with?
agree. Specially when florecent can produce lots of efficient uv A B or C.
Alibaba/aliexpress just lost my business.
They shut my account down saying I broke terms of service as a seller. I've never even signed up to sell anything.
They want me to actually scan and send them my drivers license and passport!
They say they wont reinstate my account until I do. That's not going to happen.
Unfortunatly alibaba/aliexpress is sketchy. And seemingly harvesting Canadian identifications. There are posts about it online.
Dont trust these fuckers. I placed an order for a watch, the minutes layer they shut my account down demanding I send them scans of my government issued I'd. I reversed the charges in paypal and will NEVER buy from them again.
Too bad, I hope I can contact kingbrite directly.
