XHP 50.2 and 1x18650 Selfmade

I finally decided to build the lamp with only one 18650 battery.

As an LED, I would most like this one here

How can I get the right supplies?

Is that with 7135 drivers or I need something as expensive as this: https: //www.aliexpress.com/item/32897809607.html? Spm = a2g0x.12010612.8148356.10.79721162SxsYnv

to buy ?

here are my previous thougths Cree XHP35.2 Maschinenprojekt

Personally, I would step down a bit from the XHP50.2 for an EDC, maybe an XML2.
While good, just way too much power IMHO and not much for flexibility thanks to the driver hehehehe :wink:
I have made a one similar, but with a Convoy S21A, and the H1A driver from KaiDomain, all 21700.
Would love to find an FET+7+1 driver I can buy right away, as I have yet to find one, so I’m waiting for parts to arrive for the Texas Avenger series 20mm.
