Unrivaled Quality Control Measures: 50+ Tests Per Product

Raw Material Testing

We test aluminum ingots for purity to ensure good heat performance. Lamp beads are also checked, including LM80 testing, to guarantee quality. This ensures our lights are durable and perform well.

Waterproof Testing

Our rigorous waterproof test involves submerging each light to ensure that every light meets high standards of water resistance. In case any light fails, a thorough re-inspection of the entire batch is conducted to maintain uncompromising quality.

Color Temperature Testing

Color temperature test guarantees each light delivers consistent and accurate lighting. This process confirms that the color temperature meets the required specifications, maintaining uniformity across all products.

Power Supply Testing

Surge Protection Test: Our lights undergo surge protection testing to ensure they can withstand power fluctuations, maintaining performance and safety. High Voltage Test: High voltage testing checks the light's endurance against electrical stress, ensuring it can operate reliably under various voltage conditions.

Aging Testing

Each light undergoes a 24-hour continuous lighting test post-packaging to confirm immediate performance. Additionally, small batches from each production run are continuously tested for a month to assess durability and ensure consistent long-term performance.

Integrating Sphere Testing

Using integrating spheres, we measure critical electrical parameters such as power (W), color rendering index (CRI), and color temperature, ensuring every light meets our high-quality standards.

Temperature and Humidity Testing

Our temperature and humidity test simulates real-world conditions from -40°C to 150°C and up to 98% humidity, confirming that our lights consistently maintain reliable performance in diverse and extreme environments.

Dark Room Testing

Dark room test assesses the light distribution and beam angles of our lights. By measuring at a 10.3-meter distance, this test accurately evaluates the uniformity and precision of our lighting solutions.

Salt Spray Testing

To ensure corrosion resistance, screws are subjected to a 48-72 hour test. Light casings are tested for over 1000 hours, with some undergoing up to 2000 hours to withstand extreme conditions.

Finished Product Testing

WOSEN LED lights go through a series of strict tests, including lightning strike, impact, drop, UV, power-on, and safety tests. These tests ensure our lights meet the highest quality and performance requirements.
