Test Equipment & Setup
| Item | Details |
|---|---|
| Test Equipment | Thermal Shock Chamber (冷热冲击箱) |
| Room Temperature | 23 °C |
| Room Humidity | 60 % |
| High-Temperature Set Point | 70 °C |
| Low-Temperature Set Point | −20 °C |
| Soak Duration (each condition) | 2 hours |
Test Procedure
- Pre-test: Record sample IDs (CL2-1#, CL2-2#) and confirm ambient conditions — 23 °C, 60 % RH.
- High-temperature conditioning: Place samples in thermal shock chamber set to 70 °C; allow to stabilise for 2 hours.
- High-temperature functional check: Power on samples; cycle through all brightness levels; verify switching and power-on/off button response.
- Low-temperature conditioning: Set chamber to −20 °C; allow samples to stabilise for 2 hours.
- Low-temperature functional check: Power on samples; cycle through all brightness levels; verify switching and power-on/off button response.
- Post-test: Return samples to room temperature; document observations, capture test pictures, and record results.
- Acceptance criterion: Samples must illuminate normally at all brightness levels and respond correctly to all button inputs throughout the specified temperature range.
Test Data & Results
| Sample ID | Test Condition | Issue Description / Observations |
|---|---|---|
| CL2-1#–2# | High-Temperature Illumination Test (70 °C) | After storing the samples in a 70 °C environment for 2 hours, powering on the lantern showed no change in brightness at any level; power-on/off button switching operated normally. |
| CL2-1#–2# | Low-Temperature Illumination Test (−20 °C) | After storing the samples in a −20 °C environment for 2 hours, powering on the lantern showed no change in brightness at any level; power-on/off button switching operated normally. |
Overall Test Result: Samples passed the high- and low-temperature test procedure; normal illumination was achieved at all specified operating temperatures.
Test Pictures: Captured on-site during testing (see original report appendix).
Conclusion

Frequently Asked Questions
What temperature range does the ETENWOLF CL6 Camping Lantern operate in?
The CL6 is validated to operate normally from −20 °C to 70 °C. Both extremes were tested with a 2-hour stabilisation soak, and the lantern maintained full brightness at all levels with no control issues.
What test standard was used for the CL6 operating temperature test?
The test followed ETENWOLF’s Internal Control Standard (内控标准). The acceptance criterion requires the lantern to illuminate normally at all brightness levels throughout the specified temperature range.
How long were the CL6 samples conditioned before the temperature test?
Samples were placed in a thermal shock chamber and allowed to stabilise for 2 hours at each target temperature (−20 °C and 70 °C) before functional checks were performed.
Did the CL6 Camping Lantern pass the operating temperature test?
Yes. Both test samples (CL2-1# and CL2-2#) passed. No brightness variation was observed at any level, and button switching functioned correctly at both −20 °C and 70 °C.
