Test Equipment & Setup
| Item | Detail |
|---|---|
| Test Equipment | Illuminance Meter (照度计, unit: LX / LUX) |
| Measurement Distance | 10 cm |
| Measurement Location | Darkroom, on the optical axis of the LED lamp |
| Light Mode Tested | Front white light (正面白光) |
| Room Temperature | 23 °C |
| Relative Humidity | 60 % |
| Test Conditions Label | ROOM TEMP. & HUMIDITY: 23 °C, 60 % |
| Photo Reference | 10 cm LED high-brightness photo (10cm LED高亮); image reference index: 9 |
Test Procedure
- Pre-Test: Prepare 2 PCS S1 samples. Allow samples to acclimatize to room temperature (23 °C) and humidity (60 %) conditions.
- Equipment Setup: Power on the calibrated illuminance meter (LX unit). Position the meter probe on the optical axis of the LED lamp at exactly 10 cm from the light-emitting surface.
- Environment: Conduct all measurements inside a darkroom to eliminate ambient light interference.
- Measurement: Activate the front white light mode on each sample. Record the maximum illuminance value (LUX) displayed on the illuminance meter for each sample individually.
- Post-Test: Record results, capture test photos (reference: 10 cm LED high-brightness image), and evaluate uniformity of range and luminous intensity.
- Acceptance Criteria: Results are evaluated against range and luminous intensity uniformity standards. This test is classified as For Reference Only (供参考).
Test Data & Results
| Sample No. (编号) | Distance (cm) (距离) | Light Mode (灯光) | Illuminance Value / LUX (照度值) |
|---|---|---|---|
| 1# | 10 | Front white light (正面白光) | 277 |
| 2# | 10 | Front white light (正面白光) | 286 |
Observations: Both samples were tested under identical conditions (10 cm distance, front white light, darkroom). Sample 1# registered 277 LUX and Sample 2# registered 286 LUX, yielding a spread of 9 LUX between the two units. The test image (10cm LED高亮, index 9) was captured for visual documentation. Remarks/Notes field was left blank by the tester.

Frequently Asked Questions
What illuminance does the ETENWOLF S1 LED light produce at 10 cm?
In controlled darkroom testing at 10 cm distance, the ETENWOLF S1’s front white LED lamp measured between 277 LUX and 286 LUX across two production samples, with a maximum recorded value of 286 LUX.
What test standard was used for the S1 LED illuminance test?
The test was conducted against ETENWOLF’s internal standard focused on range and luminous intensity uniformity evaluation. No external standard (such as IEC or ISO) was referenced for this specific test; results are filed for reference only.
What equipment was used to measure the S1 LED brightness?
An illuminance meter (照度计) measuring in LUX was used. Measurements were taken in a darkroom at exactly 10 cm from the LED light source on the optical axis to ensure accuracy and eliminate ambient light interference.
Does the ETENWOLF S1 tire inflator have a functional LED light?
Yes. The ETENWOLF S1 portable tire inflator includes a built-in front white LED lamp. Based on illuminance testing, it delivers up to 286 LUX at 10 cm, making it suitable for use in low-light conditions such as roadside tire inflation at night.
