I’m planning to buy an A4 bin for real pretty soon, preferably before the factory closes during new year and Chinese new year.
However, due higher MOQ than planned, I will very much prefer the interest list number to hit 50 pcs before doing so. Otherwise, I will take a fairly big financial hit.
Hmm, it depends on if my next mod will work, but ok, I’m in for one A4 bin led.
So 20mm 12v mcpcb only right? We can’t get them in 18mm or 16mm or 6v version correct? Otherwise I would buy more.
Yeah, only 20mm/ 12v.
Alright guys, the A4 bin is coming, probably tomorrow.
You can start paying. Refer to the first few lines on the OP for payment. I will PM you later if you haven’t by then.
I payed for one A4 bin led, ordinary WW shipping, thanks! 
PP sent, standard 4$ shipping
Paid for two A4
Due to some recent developments (My GPU dying a few days ago), I think that 1 LED is enough for me. If someone else wants my 2nd LED, you are welcome to it.
If not then I will find a way to order both of them.
Interested in one 4000K.
Paid for 2 4000K - standard shipping
You can have one of my reserved LED’s.
Already PMed but wanted to get on the list. I am in for one 4000K.
Paid thanks!
interested in 2 5000K
Thanks
Here we are,
Die porn shot, A5 bin from previous sampling on the left, and the A4 (mass produced) on the right.
Color variation test on two LEDs @4000k: not exactly equal but at least both can be considered in a rosy territory.
As happened in the djozz's samples, the chip on the LEDs indeed aren't perfectly matched. At 9.0v we might see an entire row almost gone missing.
Bumping the voltage slightly to 9.3v and the entire array now lit up fairly evenly. Luckily, at 9.3v my lab bench didn't even register 10ma current-wise. So, the voltage mismatch doesn't seem as serious as it would look at 9.0v. For aesthetics reason, however, you might want to keep the voltage (esp. for ultra-low mode) at 9.3v or above.
I would like 2 x A4 (4000K) please. What do I need to do?
Check the price on the OP and the shipping method you desire. Then you calculate the sum and pay. Link for payment already given on the OP.
What is the difference between “standard” and “ordinary” shipping?
With (L or R) or without tracking (U)
