The new SP33 V3 features:
- XHP50.2 3V (6.000 - 6.500K) instead of XHP50.2 6V (6.000 - 6.500K)
- Subsequently, it uses an FET driver instead of a boost driver
- It outputs 3.500lm instead of 2.500lm (like SP33 V2)
- USB-C port
- 21700 support
- much better UI with better stepped modes (e.g. moonlight with 1lm) and ramping mode
- new advanced temperature regulation (ATR) without timed stepdown
- smart heat control (brightness will step again if temperature decreases)
