How to Test the Outdoor Performance of Solar Lights？

1. Brightness and light source performance
Brightness performance

High-brightness models can reach 2055 lumens, which can cover large-area lighting needs (such as camping and stall scenes).
LED light source life is up to tens of thousands of hours, and the energy-saving efficiency is 3-10 times that of traditional bulbs.
Support multi-color light sources (white light/yellow light/natural light), flash mode, etc., to adapt to different scenes.

Light uniformity

The wall washer design can evenly project light onto the wall or ground to avoid light spots, suitable for courtyard and villa decoration.

2. Battery life and charging efficiency
Dual charging method

Support solar charging (full in 4-6 hours during the day) + USB emergency charging, and can switch to backup power supply on rainy days36.
Large-capacity lithium battery life is up to 20 hours (high brightness mode) to 72 hours (energy-saving mode).

Adaptability to rainy days

High-quality products can support normal lighting for 2-3 consecutive rainy days, and high-capacity batteries (such as ≥10000mAh) need to be selected.

3. Durability and environmental adaptability
Protection level

IP65/IP66 waterproof and dustproof standards, can withstand heavy rain and dusty environments.
Aluminum alloy shell + anti-corrosion coating, wind and corrosion resistance, service life ≥ 5 years.

Extreme temperature performance

Working temperature range: -20℃~50℃, built-in heat dissipation design to prevent high temperature attenuation.

4. Intelligent functions and user experience
Automatic control

Light sensitivity: automatically lights up when the light is lower than 10lux, and turns off at dawn.
Human body sensing: Some models support nighttime human/moving object recognition, triggering high-brightness lighting.

Convenient operation

The remote control or mobile phone APP controls brightness and mode switching, and some support voice commands.

5. Installation and maintenance
Wiring-free design

Magnetic suction, ground plug, hanging and multiple installation methods, one person can complete it in 10 minutes.
Modular structure facilitates replacement of batteries or light boards.

Maintenance cost

Clean the solar panel once a month (wipe with a soft cloth), and replace the battery every 3-5 years.

6. Authoritative certification and testing
Safety standards

Export products must pass UL1703 (USA) or CE (EU) certification, covering fire protection, leakage protection, etc..
Domestic products must comply with the "GB/T 35264-2017 Solar Street Light" standard to ensure charging and discharging stability.

Third-party testing

Laboratory tests include:
Salt spray test: verify corrosion resistance.
Dust and waterproof test: simulate sandstorm and rainstorm environment.

7. User reputation and cost-effectiveness
High cost-effective brand recommendation

Lvye, Siemens, Philips: comprehensive score ≥4.8/5, failure rate <2%.
Night market stall scene: recommended power ≥1000W model, price range 200-500 yuan.

Common complaints

Low-priced products have false illumination time (claimed to be 8 hours but actually ≤ 3 hours) .
Solar panels are prone to dust accumulation, affecting charging efficiency, and require regular maintenance
