| Model / Specification | FL1 |
| Sample Quantity / No. | 3 PCS (FL1-10#, FL1-11#, FL1-12#) |
| Test Purpose | Evaluate illuminance values and beam spot size of the FL1 flashlight |
| Test Conditions | Room temperature 23 °C, relative humidity 60 % |
Test Equipment & Setup
| Equipment | Details |
|---|---|
| Illuminance Meter (照度计) | Used to measure lux values at specified distances and angles |
| Parameter | Value |
|---|---|
| Measurement distances | 1 m, 5 m, and 10 cm (centre LED) |
| Measurement angle | 0° (on-axis) |
| Lighting modes | White + Yellow combined; Yellow only; Spotlight (white) |
| Ambient temperature | 23 °C |
| Relative humidity | 60 % |
Test Procedure
- Pre-test: Confirm all samples are fully charged and functioning. Record sample IDs (FL1-10#, FL1-11#, FL1-12#). Set ambient conditions to 23 °C / 60 % RH.
- Illuminance at 1 m: Power on each sample. With the illuminance meter placed at 1 m, 0° angle, record lux readings for each of the three modes: White + Yellow combined, Yellow only, and Spotlight (white).
- Beam spot diameter at 1 m: With the sample powered on at 1 m distance, measure the projected beam spot diameter (in metres) for each mode.
- Beam spot diameter at 5 m: Repeat beam spot diameter measurement at 5 m distance for each mode. Illuminance at 5 m is not recorded (noted as “/”).
- Centre-LED illuminance at 10 cm: Place the illuminance meter 10 cm from the centre LED. Record the lux value for the spotlight/centre LED.
- Post-test: Compare results against internal acceptance criteria. Document observations and photographs. Complete test assessment form.
Acceptance criteria: Internal standard (no published numeric threshold cited in this report). Samples are assessed Pass / Fail based on internal benchmarks.
Test Data & Results

|---|---|---|---|
| FL1-10# | 1 m | White + Yellow: 708 / Yellow: 52 / Spotlight: 1,245 | White + Yellow: ~0.8 / Yellow: 0.7 / Spotlight: 0.8 |

| Centre LED 10 cm | 5,040 | — | |
| FL1-11# | 1 m | White + Yellow: 871 / Yellow: 46 / Spotlight: 1,712 | White + Yellow: ~0.7 / Yellow: 0.6 / Spotlight: 0.8 |
| 5 m | / | White + Yellow: ~1.9 / Yellow: 1.5 / Spotlight: 1.9 | |
| Centre LED 10 cm | 5,060 | — | |
| FL1-12# | 1 m | White + Yellow: 859 / Yellow: 48 / Spotlight: 1,621 | White + Yellow: ~0.7 / Yellow: 0.6 / Spotlight: 0.8 |
| 5 m | / | White + Yellow: ~1.9 / Yellow: 1.5 / Spotlight: 1.9 | |
| Centre LED 10 cm | 5,030 | — |
Observations: Illuminance values at 1 m varied between samples, with the spotlight mode producing the highest readings (1,245 – 1,712 lux). The yellow-only mode produced the lowest illuminance (46 – 52 lux). Centre-LED readings at 10 cm were consistent across all three samples (5,030 – 5,060 lux). Beam spot diameters at 5 m were identical across all samples for each mode. Illuminance at 5 m was not measured (“/”). Test photographs were taken and referenced as image 9 in the source file.

Frequently Asked Questions
What illuminance does the ETENWOLF FL1 kids flashlight produce at 1 metre?
In spotlight mode the FL1 produced between 1,245 and 1,712 lux at 1 m (0° angle) across three tested samples. In White + Yellow combined mode readings ranged from 708 to 871 lux, while Yellow-only mode measured 46 – 52 lux.
How large is the FL1 flashlight beam spot at 5 metres?
At 5 m the beam spot diameter was approximately 1.9 m for both spotlight and White + Yellow combined modes, and 1.5 m for Yellow-only mode. These dimensions were consistent across all three tested units.
What does the Fail verdict mean for the FL1 illuminance test?
The Fail verdict indicates that one or more measured values did not meet the internal acceptance benchmarks set for this product. The report was assessed by tester Li Guanghua, reviewed by Zhang Ronggui, and approved by Mai Shaoqiang on 2025-06-06. Further design or component review is expected before re-testing.
What is the centre-LED illuminance of the FL1 flashlight at 10 cm?
Measured directly at the centre LED at a distance of 10 cm, all three samples produced very consistent readings: FL1-10# at 5,040 lux, FL1-11# at 5,060 lux, and FL1-12# at 5,030 lux.
