So, I guess it is the light then but I'm not sure. Maybe if I Google search reviews again I'll find that others are having the same issue.
The Zebralight runtimes on high assume the power is stepped down because of the heat, so you'll only get high for a short time (this is why H1 and H2 have similar runtimes but very different quoted outputs). On a bike you get a lot of cooling so it will run brighter for a shorter duration. To test the battery run it on the lowest high setting and compare the runtime (358lm for 5.1hrs as listed below for the SC600w).
- High: H1 2300 Lm (PID, approx. 1.8 hours) or H2 1311 Lm (PID, approx. 2 hours)/705 Lm (PID, approx. 2.5 hours)/358 Lm (5.1 hours)
