Finally worked on some things from my todo list. Replaced the driver in a Sofirn LT1 with the power bank supporting driver. Used to have this as nightlight, but that task has been taken over by a Fireflies PL09MU. It can go much lower brightness and made the LT1 useless for that purpose. So that’s now the emergency light and phone charger for when the power goes out.
Also removed a bunch of LH351Ds from a few Sofirn pro lights (SC21 and SP10). 519As are on the way and will be put in there. So now hosts are cleaned up and ready. Only reflow 519As and re-assambly left once emitters arrive.
Had a SC31 pro lying around that got a SFT40 now. Originally intended for other purposes, but due to too high current choices were limited. The original SST40 was actually not too bad, so that one went into a Astrolux FT03 that originally had a XHP50.2 (that was emitting blue light after a failed slicing attempt). Unfortunately the result was still ugly (it’s the reflector, not the emitter!), so that one can go back into the spare parts bin.
Edit:
A quick test outside with the SC31 pro and SFT40 revealed a really distracting bright ring on the outside of the spill. Not a good combo with stock reflector.
Hadn’t thought about that… it’s late at night here
Without lens the ring disappears. Most extreme lens effect I’ve ever seen…
Edit:
Tried to use an AR lens from a Convoy S2+, but it doesn’t fit. It’s ever so slightly wider and gets stuck in the SC31’s bezel halfway. To be continued.
6500K D2 1A 80cris and 3000 K 30G B2 90cris.
I also modified the driver for higher output. 3.1A in this case.
Host has 4,5mm deep driver cavity so inductor fits nicely. It’s milled deeper after anodizing as you can see the border of old cavity.
And all assembled. 3000K’s seem to have smaller light emitting surface.
Beam quality is nice. Beam profile is similar to XP-L hi. Still I might switch 3000K C4 binned 80cri ones in place of these 90cri leds because now 6500K leds overpower them in higher output levels causing CCT to became drastically colder.
Completed my first reflow today. 3 Cree XP-E2 528nm Green on a Noctigon 20mm 3xp mcpcb. I tested it with my multimeter and was thrilled that they all lit up. This will be going into a green Convoy S2+.
You will need to enlarge the washer/spacer hole (metal or plastic) that sits on the switch, because the forward switch is larger than the reverse switch.
Also, as it is taller, you will probably need to cut or trim that inner “tongue” from the rubber cap.
When soldering the switch to the PCB, make sure the solder or the switch metal pads don’t protrude so that you don’t risk provoking short circuits.
I “stole” GetKongs T3 triple idea and did it too
FWAA TIR lens and MCPCB together with the 17mm 5A Convoy driver and a spacer built from multiple 16mm 3535 copper MCPCBs I had laying around
But I couldnt leave my FWAA in my spare parts bin so I made it into an XHP50.2 mule:
L2 love here, too. Put the SFT40 in there with a Led4Power driver and Simon’s new plastic lighted switches, 26800 single. I wonder what I will ever do with the old LD29 driver…those seem to have disappeared for good now.
