Test Equipment & Setup
| Parameter | Value |
|---|---|
| Instrument | Illuminance Meter (LX) |
| Measurement Distance | 10 cm |
| Test Environment | Darkroom |
| Measurement Target | Maximum illuminance on the optical axis of the light |
| Ambient Temperature | 23 °C |
| Ambient Humidity | 60 %RH |
Test Procedure
- Pre-test: Confirm the darkroom environment is fully light-sealed. Power on and zero the illuminance meter (LX). Verify ambient temperature (23 °C) and humidity (60 %RH).
- Sample placement: Position the C2PV unit so that the flashlight lens is directed at the illuminance meter sensor at a fixed distance of 10 cm along the optical axis.
- Procedure: Activate the flashlight in spotlight (聚光) mode. Record the maximum illuminance reading displayed on the meter in LUX.
- Repeat: Perform the measurement for each of the three samples (4#, 5#, 6#) independently under identical conditions.
- Post-test: Power off all equipment. Document all readings in the test record.
- Acceptance Criteria: Results are for reference only — no pass/fail threshold applies. The objective is to characterize the maximum optical axis illuminance of the C2PV light source.
Test Data & Results
| Sample No. | Distance (cm) | Light Mode | Illuminance (LUX) |
|---|---|---|---|
| 4# | 10 | Flashlight Spotlight | 119 |
| 5# | 10 | Flashlight Spotlight | 136 |
| 6# | 10 | Flashlight Spotlight | 117 |
Observations: All three samples produced consistent spotlight illuminance values at 10 cm. Sample 5# recorded the highest value at 136 LUX, while samples 4# and 6# were closely grouped at 119 LUX and 117 LUX respectively. The spread of 19 LUX across units is within normal unit-to-unit variation for LED light sources at this distance. Test images were captured at 10 cm flashlight spotlight condition (reference image index: 9).

Frequently Asked Questions
What illuminance does the ETENWOLF C2PV flashlight produce at 10 cm?
In spotlight mode at 10 cm distance, the C2PV produced illuminance values of 119, 136, and 117 LUX across three tested samples, giving a range of 117–136 LUX. This measurement was taken on the optical axis in a darkroom using a calibrated illuminance meter.
What test standard was used for the C2PV illuminance test?
The test was conducted against an internal standard focused on range and light intensity uniformity assessment. It is not based on a published external standard such as IEC or ANSI. Results are therefore classified as for reference only, with no defined pass/fail threshold.
Is the C2PV flashlight beam suitable for practical use based on this test?
The 117–136 LUX range at 10 cm is consistent with a focused LED spotlight on a compact inflation tool. While the test data is provided for reference and not benchmarked against an external standard, the values indicate a usable light source for close-range tasks such as roadside tire inflation in low-light conditions.
How many samples were tested in the C2PV illuminance test?
Three samples were tested, labeled 4#, 5#, and 6#. All three were evaluated under identical conditions: flashlight spotlight mode, 10 cm distance, darkroom environment, 23 °C and 60 %RH ambient conditions.
