Key Findings
The ETENWOLF CL3 Camping Lantern was tested across six lighting modes at 1 m distance in a dark room, confirming that side white light delivers the highest illuminance at up to 71 lux while red light operates at the lowest output (~3.7 lux), consistent with its use as a low-disruption night mode. Results are provided for reference.

| Product No./Name | Camping Lantern |
| Model | CL3 |
| Sample Quantity/No. | 2 PCS |
| Test Purpose | Verify that the product’s actual lighting performance matches its nominal parameters and evaluate its suitability for camping-scene illumination. |
| Test Conditions | Room temperature 23 °C, relative humidity 60% |
Test Equipment & Setup
| Item | Detail |
|---|---|
| Test Equipment | Illuminance Meter (LX), measurement range 0–20,000 lx |
| Measurement Distance | 1 m from light source |
| Probe Orientation | Horizontal, aligned with lamp axis |
| Environment | Dark room |
| Temperature | 23 °C |
| Relative Humidity | 60% |
Test Procedure
- Pre-test: Verify the illuminance meter is calibrated and within the 0–20,000 lx range. Confirm the test environment is a fully darkened room with no ambient light interference.
- Setup: Position the illuminance meter probe horizontally at a distance of 1 m from the CL3 lamp axis.
- Procedure: Activate each lighting mode in sequence (side white, side amber, side white one-side, side red, bottom white, bottom green). Record the peak illuminance reading for each mode for both sample units (1# and 2#).
- Post-test: Power off the device. Document all readings and compare against nominal parameters.
- Acceptance Criteria: Results must confirm the product meets the lighting performance requirements for diverse camping scenarios. Final disposition is for reference only.
Test Data & Results
| Sample No. | Distance (m) | Lighting Mode | Illuminance — Unit 1# (lux) | Illuminance — Unit 2# (lux) |
|---|---|---|---|---|
| 1#/2# | 1 | Side White Light | 71 | 66 |
| 1#/2# | 1 | Side Amber Light | 56 | 52 |
| 1#/2# | 1 | Side White Light (One Side Only) | 31 | 26 |
| 1#/2# | 1 | Side Red Light | 3.7 | 3.6 |
| 1#/2# | 1 | Bottom White Light | 42 | 32 |
| 1#/2# | 1 | Bottom Green Light | 43 | 34 |
Observations: Side white light (both sides active) produces the highest illuminance across both units (71 lux / 66 lux). Side red light is intentionally the lowest output mode at 3.7 lux / 3.6 lux, suitable for preserving night vision. Unit 1# consistently reads higher than Unit 2# across all modes, though both fall within a reasonable sample-to-sample variance. Bottom white and bottom green modes deliver comparable output (~32–43 lux range), suitable for close-range task lighting. Test images on file reference: side white light, side amber light, side white one-side, side red light, bottom white light, and bottom green light.

Frequently Asked Questions
What illuminance does the ETENWOLF CL3 produce at 1 meter?
At 1 m distance in a dark room, the CL3 reaches up to 71 lux in side white light mode (full output). Side amber light measures 56 lux, bottom white and bottom green each reach the low 30s to low 40s lux, and side red light outputs approximately 3.6–3.7 lux for minimal night-vision disruption.
What lighting modes does the CL3 camping lantern offer?
The CL3 offers six modes: side white light (both sides), side amber light, side white light (one side only), side red light, bottom white light, and bottom green light. This range covers general camp illumination, warm ambient lighting, task lighting, and low-disruption night use.
Why is the CL3 test verdict listed as “For Reference Only” rather than Pass or Fail?
The illuminance test uses an internal standard rather than a published third-party specification, and the test purpose is to characterize real-world performance against nominal parameters. A “For Reference Only” designation means the data is valid and documented but is used as a performance benchmark rather than a binary compliance decision.
How does the CL3 side red light mode compare to other modes in illuminance?
Side red light is the lowest-output mode at 3.6–3.7 lux at 1 m — roughly 19× dimmer than the full side white light mode. This is intentional: red light minimally affects dark-adapted vision, making it well suited for nighttime camp navigation or reading without disrupting sleep cycles.
