I got the little FandyFire Rook from FMcamaroZ28 and really like how it’s a minature king. It’s got a single XM-L emitter and a nice reflector so I decided to change out the emitter for something a little more exotic, and since I had a second Luminus SST-90 I figured “Why not?” I don’t want to run this one max out like the one in the C8, so I figured I’d have a look at the driver and see if I could maybe just bump it’s output a little, it’s got 2 levels, Hi and Lo and a hidden strobe.
The aluminum star under the XM-L is Very thick! Probably 2.5mm, haven’t measured it yet but it’s much thicker than a Noctigon. So I’ll have to shim up a Noctigon with some copper sheet in order for the emitter’s height to be correct. I’ll also have to open up the reflector to fit over the large dome.
But popping the driver out, I got a surprise! It’s got an FET on board, AND 6 7135 chips! Now what? Figured I’d take pics and let y’all tell me how to go about this one…Comfy, you watching?
Is this little yellow part melted? It looks blackened on one end, and it appears to have a puddle of black melted plastic at the board junction, what’s up with that?
An inductor?
One of 6 7135 chips, 3 widely spaced on this side of the vertical board, 3 closely spaced on the other side…
The FET
An unknown MCU sitting close to the apprently burned yellow component…
So, with both an FET and 7135 chips, how do I bump this one up to between 3 and 4 amps? Simply stack some 7135 chips? Or take a different approach altogether? I’ve never seen a driver like this one before. Any help will be greatly appreciated! I’m looking for that 3-4A range so the SST-90 will still be comparatively efficient and making some 1100-1200 lumens.
Thanks a bunch for your help!
Sorry for the sloppy pics, tried the digital zoom on my G1X…handheld at 16x it did pretty good I thought.
