Test Procedure

Pre-test: Record laboratory ambient conditions — temperature 22 °C, humidity 55 % RH. Inspect and document the initial electrical and structural condition of both CL6 samples.
Sample placement: Place 2 PCS CL6 Camping Lanterns inside the constant temperature and humidity test chamber according to the chamber loading diagram.
Cycle execution: Set the chamber controller to run repeating cycles as follows — Phase A: ramp to 60 °C / 80 % RH, hold for 2 hours; Phase B: ramp to −20 °C (no humidity control), hold for 2 hours. Continue cycling until 72 hours of total test time have elapsed.
Program monitoring: Verify cycle progression against Program Control Diagram 1 and Program Control Diagram 2 throughout the test.
Post-test inspection: Remove samples from the chamber after 72 hours. Allow samples to return to ambient conditions. Verify electrical performance and structural integrity against acceptance criteria.
Acceptance criteria: Electrical performance must be normal (OK) and structural features must be intact (OK) for a Pass verdict.

Frequently Asked Questions

What test conditions were used in the CL6 Camping Lantern temperature and humidity cycling test?

The CL6 was subjected to alternating cycles of 60 °C at 80 % relative humidity (high-temperature phase) and −20 °C (low-temperature phase), each phase lasting 2 hours, for a total of 72 continuous hours. The test was conducted in a constant temperature and humidity chamber with the laboratory ambient set at 22 °C and 55 % RH.

Did the ETENWOLF CL6 Camping Lantern pass the high/low temperature humidity cycling test?

Yes. Both samples of the CL6 Camping Lantern passed the test with an overall verdict of Pass (合格). Electrical performance and structural integrity were both confirmed normal (OK) after 72 hours of temperature and humidity cycling between 60 °C / 80 % RH and −20 °C.

What does the high/low temperature humidity cycling test verify for camping lanterns?

This test verifies the reliability of a camping lantern under extreme environmental conditions — simulating real-world use cases such as sudden temperature swings, condensation from heat and humidity, and exposure to freezing cold. It confirms that the product’s electrical systems and physical structure remain functional after repeated thermal stress cycles.

How many samples of the CL6 were tested and who conducted the test?

Two samples (2 PCS) of the CL6 Camping Lantern were tested. The test was conducted by Su Yimei (粟仪梅) under report number 2026011401, with the test period running from January 11 to January 14, 2026.
