The TS10 is an SC21 Pro without USB-C charging
SC21 Pro came first, it is 1.4mm fatter and 1mm longer than the TS10
the SC21 Pro has a 16340 battery, while the TS10 has a 14500 battery
Timeline
Sofirn had created the SC21 Pro. It has built in charging and a 16340 battery. It has a lighted sideswitch, a tailmagnet and uses a Reflector with an LH351D 5000K High CRI LED. The beam has a throwy hotspot, plus spill.
Then Lumintop made the Floody FWAA, 14500 and Anduril, no USB, no Aux. Wurkkos modeled the TS10 after the FWAA, and had Sofirn manufacture the TS10 with the driver from the SC21 Pro.
The TS10 is my favorite of the three, because of the tailswitch and form factor.
But for a USB light w Anduril, I reach for my SC21 Pro. The LED can be changed to Nichia, and the reflector can be replaced with a Pebbled Tir for a floody beam.
The switch button on the SC21 Pro is tiny and hard to find by feel, but the illuminated button makes it easy to locate on a dark nightstand and while in use. The stock firmware 2022-02-08 lacks LVP on Aux same as on first batch TS10. Firmware can be reflashed to fix that, and add firefly lows.
The unique flashing adapter available from gchart, is not the same as the TS10 flashing adapter.
Here is the download link to the 2022-10-12 firmware from gchart, that I like to use. If interested in battery conservation, Ceilings should be changed to 110/150 = 315 lumens.
Reflashing to any version of new firmware adds LVP to Aux, adds firefly lows. The gchart firmware has an advantage over newer firmware, because the Aux button goes to high bright while in use above the regulated 7135 chip, at 150 lumens on the stock LH351d.
Also, opening and closing the light with the gchart firmware, the first turns on at the max regulated output by default. imo very convenient, and better than later versions of firmware that abandon using the button light as an indication when top of regulated output is passed.
Battery check on the gchart firmware uses 1 decimal place, which I like better than newer firmware w 2 decimals.
The tailmagnet has good strength, it holds securely to the side of the fridge.
