This is interesting.. http://led-mounting-bases.com/en/led-mcpcb/16853-star-pcb-for-4-leds-cree-xq-e.html

Wonder how hard it’ll be to convince them to make a 3×3

Have you checked out they boards Clemence had made? Perhaps he could whip up a 3×3 after we try this in a 2×2 config.

2 pc XD16 will fit perfectly on VR16S1. Up to 4 pcs in 4p config (scraping required). Not so with the VR16SP4….

E21A on VR16SP4 (rev. 2)

XD16 on VR16SP4

Zoomed in
The XD16 pads oversized the E21A pads by 0,17mm (at three sides), and the gaps is 0,3 mm as opposed to 0,2 mm with E21A. The board can be used but not a perfect match.

Please make single pad dtp board in classic size (17 and 20 mm). Even if it will not reach surface brightness(probably it will not but fingers crossed) of lets say old version XP-G2 it should be very good performer for single cell fet flashlight(especially aspherical version)
Hope someone will send them to Djozz for testing and of course with your DTP board.

I saw similar comments when the XPL-HI was released. I think it will take a long time before dedoming is a thing of the past Smile

I want to get my hands on some of these too!

For me personally dedoming did become a thing of the past with the Cree HI LEDs. I hate the tint shift with dedoming so for throw applications I only use the current HI LEDs. I don’t do 1000 meter throw lights though, it’s not my cup of tea. These new ones look real interesting though! Eager to try them out.

Now we need to wait for mcpcbs to mount to.

Got my shipment from arrow. I’m making a board with 1.6mm thick copper. The two pieces will be adhered together with JB weld. It will be electrically insulated from the shelf with some kapton tape.

I will do lumen measurements on this one and put it in an X6 to do throw measurements. I then have a design for a 3×3 3V array. LOL

Could you use thermal tape to adhere your invention to the pill? Something like what Taskled use to stick there drivers down with.
Heres a link to Cutter for thermal tape.

My current and or voltage measurements are only relevent to anything that I measure.

Interesting, can’t wait to see the results. I have an mcpcb coming from Clemence to test these out myself at some point.

That tape looks pretty good, but I think I have a good plan. Instead of covering the whole surface with kapton tape, I’ll use just small strips to isolate the board from the shelf, leaving mostly air separating the two. The space will be filled with thermal paste. This kapton tape is 50 microns thick, so it will be just a bit thicker than a normal application of thermal paste.
