| Sample Quantity / No. | 10 PCS (FL1-1# through FL1-10#) |
| Test Environment | Room temperature 23 °C, relative humidity 60 % |
| Test Purpose | Evaluate the illuminance value of the FL1 flashlight |
Test Equipment & Setup
| Item | Details |
|---|---|
| Test Equipment | Illuminance Meter (照度计) |
| Measurement Distance | 1 metre |
| Measurement Angle | 0° (on-axis) |
| Light Mode | White light, spotlight / focused beam mode |
| Device State | Powered on |
| Ambient Temperature | 23 °C |
| Relative Humidity | 60 % |
Test Procedure
- Pre-test: Verify ambient conditions are at room temperature (23 °C) and 60 % relative humidity. Confirm all 10 samples are fully charged and functional.
- Setup: Position the illuminance meter at a fixed distance of 1 metre from the flashlight lens, aligned at 0° on the central axis.
- Activation: Power on each sample and set to white light spotlight (focused beam) mode.
- Measurement: Record the illuminance value (lux) displayed on the meter for each sample individually.
- Repeat: Perform the measurement for all 10 samples (FL1-1# through FL1-10#) in sequence.
- Post-test: Power off all samples. Document readings and observations in the test record.
- Acceptance Criteria: No numeric pass/fail threshold defined; results are recorded for reference only (internal standard).
Test Data & Results
| Sample No. | Distance | Illuminance (LUX) |
|---|---|---|
| FL1-1# | 1 m | 1,037 |
| FL1-2# | 1 m | 1,169 |
| FL1-3# | 1 m | 1,224 |
| FL1-4# | 1 m | 1,258 |
| FL1-5# | 1 m | 1,142 |
| FL1-6# | 1 m | 1,048 |
| FL1-7# | 1 m | 1,197 |
| FL1-8# | 1 m | 1,254 |
| FL1-9# | 1 m | 1,026 |
| FL1-10# | 1 m | 1,094 |
| Average | 1,144.9 | |
| Minimum | 1,026 | |
| Maximum | 1,258 | |
Observations: All 10 samples produced illuminance readings above 1,000 lux at 1 metre in spotlight mode. The spread of 232 lux between the lowest (FL1-9#: 1,026 lux) and highest (FL1-4#: 1,258 lux) reading represents approximately 20 % variation across the production batch, which is typical for LED-based consumer flashlights. No anomalous readings or sample failures were noted during testing. Results are designated for reference only under the applicable internal standard.

Frequently Asked Questions
What does the FL1 illuminance test measure?
The test measures the illuminance (in lux) produced by the FL1 flashlight at a fixed distance of 1 metre on the central axis (0°) while the light is set to white light spotlight mode. Lux is a measure of luminous flux per unit area received at a surface, giving a practical indication of how bright the beam is at that distance.
Why do the 10 samples show different lux readings?
Unit-to-unit variation in LED output, lens alignment, and reflector manufacturing tolerances naturally produce a spread in illuminance values across a production batch. The 232-lux range observed here (approximately 20 % of the mean) is within the normal range for consumer-grade LED flashlights and does not indicate defective units.
Is there a pass/fail threshold for this test?
No. This report was conducted against an internal standard with no defined numeric acceptance limit. The verdict is “For Reference Only,” meaning the data is used to characterise production output and inform future specifications rather than to accept or reject individual units.
What test equipment was used?
An illuminance meter (照度计) was used to capture the lux readings. Measurements were taken at room temperature (23 °C) and 60 % relative humidity, conditions which minimise environmental influence on LED output and meter accuracy.
