Test Equipment & Setup
| Item | Details |
|---|---|
| Test Equipment | Thermal Rise Tester (Thermocouple Type K) |
| Measurement Points | U1, U2, U3, U4, U5, Battery, UV LED, White LED, Bottom LED Board, Charging IC, Laboratory Ambient |
| Operation Mode | All lighting modes active simultaneously |
| Minimum Duration | 4 hours continuous, until temperature stabilizes |
| Initial Condition | Samples at ambient (room) temperature before test start |
| Laboratory Ambient — Sample 1# | 27.9 °C |
| Laboratory Ambient — Sample 2# | 31.8 °C |
Test Procedure
- Pre-test: Confirm samples are at ambient temperature and fully charged. Record laboratory ambient temperature.
- Thermocouple Attachment: Attach Type-K thermocouple probes to all designated measurement points: U1, U2, U3, U4, U5, Battery, UV LED, White LED, Bottom LED Board, and Charging IC.
- Wiring Check: Verify wiring diagram connections per the schematic (接线图) before energizing.
- Activation: Power on the CL5 and enable all LED lighting modes concurrently.
- Data Collection: Continuously record temperature at each measurement point. Maintain operation for a minimum of 4 hours or until readings stabilize, whichever is longer.
- Post-test: Record peak (maximum) temperature and calculate temperature rise (K) for each measurement point as: Temperature Rise = Peak Temperature − Laboratory Ambient Temperature.
- Assessment: Compare results against the acceptance criterion — no component damage due to overheating. Document findings per internal standard. Note any anomalies.

Observations: The highest single-point peak temperature across both samples was 116.4 °C recorded at U4 on Sample 2#, with a corresponding temperature rise of 84.6 K. U4 and the UV LED consistently showed the highest thermal loading on both samples. The battery exhibited the lowest temperature rise of all monitored points (13.3 K and 8.9 K respectively), indicating effective thermal isolation from the main driver circuitry. Full time-series data are available in the sibling sheets (温升采集变化数据-1# and 温升采集数据-2#). Note: test data from row 18 of the source report directs reviewers to those continuation sheets for the complete dataset.

Frequently Asked Questions
What is the maximum surface temperature recorded on the ETENWOLF CL5 during the thermal test?
The highest recorded peak temperature was 116.4 °C, measured at component point U4 on Sample 2# during 4 hours of continuous full-mode operation. The UV LED on Sample 1# was the second-highest point at 112.2 °C.
What does a ‘For Reference Only’ verdict mean for the CL5 thermal test?
A ‘For Reference Only’ (供参考) verdict means the test data is provided as engineering reference material. It does not constitute a formal Pass or Fail determination against a published external standard. The findings inform product design and safety review but should be interpreted alongside other qualification data.
Which component on the CL5 generates the most heat during continuous operation?
U4 consistently recorded the highest temperatures across both test samples — 113.9 °C on Sample 1# and 116.4 °C on Sample 2#. The UV LED was the second-hottest point, reaching 112.2 °C on Sample 1#. The battery remained the coolest monitored component with rises of only 13.3 K and 8.9 K respectively.
How long does the CL5 thermal test run, and what conditions are used?
The test runs for a minimum of 4 hours of continuous operation with all LED lighting modes active simultaneously, starting from ambient room temperature. Data collection continues until all monitored temperature points have stabilized. Laboratory ambient temperatures were 27.9 °C for Sample 1# and 31.8 °C for Sample 2#.
