Do you have a graph of runtime with approximate or measured output? Trying to get an idea for 20-30 minute sustained lumen output. Have you tested temperature regulation as well? I know Convoy flashlights sometimes do not regulate properly and will get too hot.
50% output after 10 minutes. In FET driver it was 20%, so improvement is significant ☺️ the stepdown begins slowly after first seconds but it it's very smooth.
