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.

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.

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.

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?

Just curious, how do people intend to use this emitter? Which host have you identified that could make use of this emitter? Since it’s 12V, and most XHP 70.2 lights are 6V, doesn’t seem like a lot of opportunities to use this. XHP35 lights are 12V but the optics/reflector will not fit over this.

Edit: The upcoming improved FT02 with XHP70.2 is said to be 12V! That seems like a great budget host for this and comes with USB-C recharge!

One host I have found is the Manta Ray C8.2 Host with 10mm reflector option can work.

Supposedly, the driver socket is 22mm, which is where 12v drivers are relatively easy to find.

Yes, shipping cost will be the 5mm’s though (or from the item with higher shipping cost, in general).

What driver are you planning to use? I only find one or two 12V drivers.

Got my Paypal shipping info too. Thanks for the quick work.

I’m planning to try the 22mm 2.3A Convoy XHP35 boost driver. I ordered it but have not received it. The mod is probably a Yootoo SD2, because I think it fits the driver reasonably well (stock driver is 23mm). Not sure how the reflector will fit, it needs at least reaming to fit around the led.
