Test Equipment & Setup
| Parameter | Details |
|---|---|
| Test Equipment | Box-type oscillating tube high-pressure water spray integrated machine |
| Room Temperature | 23 °C |
| Relative Humidity | 60 % |
| Power Source | 12 V |
| Spray Duration | 3 minutes continuous |
| Spray Angle | Arbitrary angle (all directions) |
| Water Pressure | Low-pressure water column |
Test Procedure
- Pre-test: Record ambient temperature (23 °C) and relative humidity (60 %). Verify power source is set to 12 V. Confirm 3 FL2 flashlight samples are fully assembled and in normal operating condition.
- Sample Placement: Position samples inside the box-type oscillating tube spray machine per standard placement orientation (see test placement photo).
- Spray Test: Apply low-pressure water column spray at arbitrary angles to the enclosure continuously for 3 minutes.
- Post-test Disassembly: Immediately after spray ends, disassemble each sample and visually inspect the interior for any signs of water ingress or moisture traces.
- Acceptance Criteria: No water traces or moisture detected inside the enclosure. Sample must meet IPX4 waterproof rating — protected against water spray from any direction.

Frequently Asked Questions
What does IPX4 waterproof rating mean for the ETENWOLF FL2 flashlight?
IPX4 means the FL2 flashlight is protected against water spray from any direction. It can withstand low-pressure water splashes at arbitrary angles without water entering the enclosure, making it suitable for use in rain or wet outdoor conditions.
How was the FL2 flashlight waterproof test conducted?
The FL2 was subjected to continuous low-pressure water column spray at arbitrary angles for 3 minutes using a box-type oscillating tube spray machine at 23 °C and 60 % relative humidity. Each sample was immediately disassembled after the test and inspected internally for any signs of water ingress.
Did the ETENWOLF FL2 flashlight pass the IPX4 waterproof test?
Yes. All 3 FL2 flashlight samples tested on 2025-11-03 showed no internal water traces after the 3-minute spray test. The results confirm the FL2 meets IPX4 waterproof rating requirements. The report is classified as for reference only per internal quality documentation procedures.
What standard was used for the FL2 flashlight waterproof test?
The test was conducted against ETENWOLF’s internal control standard aligned with IPX4 enclosure protection criteria. IPX4 is defined under the IEC 60529 international standard for degrees of protection provided by enclosures.
