Interest list: Q8 MCPCB with XHP50.2@5000K [DTP only available now at LED4Power]

[flightless22]

Here’s the official (Q8 modding thread ) It needs a of tweaks to get the best performance. Adding to whats already been said. The driver led wires need to replaced with thicker ones. The tailcap screws need to be replaced with brass screws and the FET needs to be replace. Hopefully someone with more experience can fill in the details.

Here’s a quote from Tom E

I don’t know the amp draw offhand of a XHP50.2, but it’s high. The stock FET is not so good, so yes a SIR404DP would be better. Actually any of those FET’s from a driver made in China is probably a fake, but most of the fakes actually perform fairly well.

Not sure how much that effects the brass contact ring, however. I’d be sure the brass ring is clean and properly treated. I’d sand it smooth, maybe apply thin amt of conductive protective grease, like NO-OX-ID.

The better FET’s, are there are a few, should stay cool, and are rated up to 60-100 amps or so.

I’ve been using these more recently: BSC009NE2LS5ATMA1, by Infineon, https://www.mouser.com/datasheet/2/196/Infineon-BSC009NE2LS5-DS-v02_00-EN-1731220.pdf. Actually it’s been a couple years I’ve been using these. There may be better ones now?

I’m interested, but it’d be nice to know what bin the leds are.
