Although obviously even better if the E21A becomes available in factory lights, I think the Sofirn C01 can be modified with an E21A using the VR10S1 board from Virence.

Clemence will even solder the emitter to the board for you for a very reasonable price, which is recommended due to the fragility of the E21A emitters.

The shipping cost is high, unfortunately. Apparently Indonesia doesn’t get the same absurdly cheap shipping options that China does.
