Swapped: Cheap Amazon Zoomie with YinDing 5050 LED

So this was a project I started way back in February or March and just finished it. It’s no secret that I have a soft spot for zoomies, so full disclosure there (no shame). I reviewed a couple of the “most popular flashlights on Amazon” Gearlight S1000 and S2000. The Gearlight S1000 was an 18650 size and was a decently-made host, so I decided to mod it.

It came with a one-hung-lo XM-L knockoff and made about 280 Lumens, but it was held back by a hollow pill with no LED shelf and a 1.5 amp max driver with awful PWM. I tried a Nichia 319A with no changes to the pill, and it was nice, but I wanted more. I picked up one of those YinDing 5050 round-die LEDs from AE along with a “P5000” 6A 20 mm driver. To address the hollow pill, I ground down a 5×25mm piece of aluminum bar stock to a circle that roughly fit inside the pill and press fit it in. I mounted a 1.6 mm MCPCB and secured it with the retainer so it rested against the inner lip of the pill to set the clearance. I followed behind the aluminum slug with some aluminum brazing filler rod to add more material and fill in any gaps. Now the hollow pill has a 6 mm integrated shelf. I added some thermal paste on the bare threads where it threads into the body since zoomies need help in the thermal department. I wired everything up, function tested it, and did some spring bypasses on the tail and driver. The light heats up much more evenly now with heat soaking into the body. The result:

I ran a candela test and got 78,550 cd at 5 meters using a Sanyo 18650GA. That’s about 560 meters of throw out of a sub-25mm aspheric. The beam is nice and round (no bat signal) and it throws really well with a narrow beam and a very nice spill for the flood position. It really breathed some life into an otherwise throw away zoomie.

Here’s a beamshot. That tree is about 200 m away.

Nice job! The Yin Ding is probably the best zoomie emitter. What a beautiful circle – unfortunately there appears to be a bit of light leakage.

Thanks! The leakage and artifacts were unavoidable just due to the design of the retainer. I thought about fixing that, but I like it as-is. I may get a better driver eventually though since the YinDing has another amp to give for max output.

I got it off Aliexpress from the YinDing store. Kaidomain sells them now too, but they’re more expensive there. Still lots cheaper than a CULNM1 or CulPM1.

Tha is! Yah it’s better than the 319A for sure. Much higher output.

This is more, and better, than polishing a turd. And very ironical. You gave this light the performance the original manufacturer said it would would have (and knew damned well, it did not)

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

Nice work!
Anyway, polishing a turd is actually possible.

Yes it’s ironic. This Gearlight version was pretty honest and didn’t overinflated specs like others did. Still, never anywhere near a real lashlight
