Awesome mod djozz, it’s always nice to see something that wasn’t designed to be good, being improved massively like this.
Today I modded a Maratac copper AAA with Richard’s 12mm single side FET driver (gruppydriv rev.2 fw) and Nichia 219C.
The driver is currently on sale here: MTN Group Discount Thread - Current Deal: MTN-slDD Driver
Stock LED and driver:
Before vs After, In the photos the 1.6mm thick driver is shown, but I actually ended up using the 0.8mm one. I had to reflow the nichia 219C into the stock mcpcb because the 10mm sinkpad couldn’t clear the reflector base:
Not necessary, but I added a solder blob top and a ring of solder to improve ground contact.
This is the 5000k 70CRI+ version of the 219C, as you would expect the tint is not as nice as the warmer high CRI one but I used this because of the low Vf, it allows it to pull higher amps on a 10440 compared to a XP-G2. According to my ceiling bounce test it makes about 750lm with a fresh efest 10440, on turbo the heat can be felt immediately.
