WTS/GB: [4000k ARRIVED, Test Report's In] GT-FC40 (a.k.a. XHP70's flattop, 12v 40w sister) 95 CRI, Available in 4000k, 5000k

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)

Looks very rosy :+1:

The first image comparing A5 and A4 bin “does not exist or no longer available”

Paid and PMed. Thank you.

fixed the first image.

Yesterday’s orders has been shipped.

If choosen Standard Shipping/Tracked, please check your PayPal receipt for tracking numbers.

Thailand Post no longer provides tracking numbers for ordinary shipments.

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.

rngwn, could these leds be ordered together with the 5mm leds from your other sale?

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

Thank you! :+1: I will order in the next few days.

PP tracking info received.

Thx
