Good luck and be very careful when trimming/fitting the aux board, any damage to the silicone from a too-tight aux board can make them burn up before they normally would.

Brilliant idea to pair a driver with incan bulb, not sure why I have never thought of that! I have some incan build but I always wished they have modes and LVP.
How did you fit the driver, did you keep the S2 pill?
2 Thanks
I kept the S2 pill, but the reflector isnât electrically neutral, so it needs to be insulated from the body for the driver to function. I found a random plastic piece that fit snugly on the top of the S2 pill to insulate the bottom of the bulb PCB from the top of the pill, and i used Kapton tape to insulate the edges of the reflector. The pill already had a hole on the middle from the previous laser diode swap i made, so i ran the wires through it. The pill didnât had a retaining ring (old convoy clearance trapezoidal host), the driver was soldered to it, so i just soldered it again.

Swiss Tech Klassisch emitter swap
[review] [teardown] had a brief moment of fame because of a pricing error and itâs unique design. It has a terrible driver with visible pmw and low cri emitter and non replaceable battery and itâs not very bright. My original goal was to use 219b 4500k and Anduril driver and have a replaceable 21700 but that was too ambitious so for now I decided to scale back and just do a basic emitter swap. I use these 3030 95cri emitters djozz review. The tint came out neutral and looks pretty good.

Where would I find the spacers for the s21a? Iâm looking to do a couple quads and only seem to find posts from years ago.
I just made one yesterday out of a piece of 6mm thick copper. I rough cut it to ~23mm diameter, drilled a hole in the center, used a bolt as a mandrel, chucked it in my cordless drill and ran it against a belt sander.
You could use aluminum instead of copper and plain sandpaper or a file instead of a belt sander, but then you canât solder it to the pill.
I usually make spacers with copper rounds stacked and soldered together

That doesnât look like a 519A, looks like a 219B, from both the silicone and the die size. You canât dedome those.

sorry⌠for future reference, get the LED hot, then push sideways:
1 Thank
Iâve always just pinched the dome with tweezers until I saw it separate from the glass, so far havenât broken any 519a that wayâŚ
1 Thank
Iâve always preferred the blade method, slicing then shaving. I use brand new utility blades when I can. Cut til you feel resistance of the glass, then scrape away any excess with the sharp blade. I find you get much finer control with the sharp edge as well.
1 Thank
Iâve pretty much just used my fingernail, or the plastic end of the tweezers from a swiss army knife. Usually also with a hot emitter, but it works fine cold too.
Iâve only had one failure, and that was because I accidentally picked away too much silicone while cleaning up so some blue light was leaking out.
Youâre right. Itâs definitely a 219b. I looked it up on past orders from Hank. Not sure why I thought 519a. I even have it documented 519a.

Thanks for joining the gang, kletsinger5394!
Thanks I may try this idea!
Do you know what size I would need for the s21a?
23mmĂ6mm is perfect for the S21A.
Because it has a pill that screws into the head itâs also pretty forgiving, so if your off by a mm one way or the other it probably wouldnât matter.

I see, thank you for the clarification. I assumed the spacer was similar to the S2+. After seeing photos of the pill I see that it is just a disk that is needed.

I bought a cheapo bike light set on Amazon for my new used bike that I got for free from a neighbor who left it next to the road for the taking.
I chose the front light based on that it appeared it could be taken apart (screws in front and back) in order to modify it. And sure enough I was able to replace the respectable 4000K XP-G3 LED with a 2700K SST-20.
Why? I may have lost some lumens, but I feel the lower CCT is less annoying for oncoming people and I like how it looks. I have yet to see another bike light while riding around with an incandescent looking light like this.
