ASTROLUX® ED01 Runtime - 1 min Duration

- Maximum brightness was 1106lm @00:00:03 - 85% of what is claimed by the manufacturer.
- Light measured at 808lm @30s, for ANSI FL1 Standards (except that our ambient temp is higher than 24°C).
- Low mode output test was omitted as it would take forever(days) to complete. Hence, I used 1lm value to represent LOW mode output for the first 3hrs.

ASTROLUX® ED01 Runtime - 1 hr Duration

- User can trigger back to high mode as and when, but ED01 will gradually stepdown within a minute.
- Temperature reached 47°C/ 117°F on 3rd consecutive trigger.
- We do not expect significant changes in the output for the next 1-2hrs, apart from gradual reduction of output as cell charges deplete. Hence, we decided to terminate the test around 8min mark.

ASTROLUX® ED01 Runtime - 1hr Duration

- Test terminated at 1 hour mark. Actual runtime for each level will be determined by the battery model used.
- Medium mode ran for over 3hrs straight, and I had to manually terminate my test to save my battery for over-discharging.
- No LVP protection or warning was being observed when it ran till 2.55V.
