Product Testing

Electronic Testing

We perform rigorous electronic performance testing to validate circuit stability, power efficiency, and functional integrity. This includes verifying LED drive circuits, power management systems, and component reliability, ensuring products operate safely and consistently under specified electrical conditions.

Mechanical Testing

Our mechanical testing evaluates structural strength, material durability, and resistance to physical stress. We test for tensile strength, impact resistance, and component fatigue to guarantee products can withstand the rigors of daily use, assembly, and handling.

Light Testing

Using advanced integrating sphere technology, we conduct precise photometric and colorimetric testing. This includes measuring luminous flux, color temperature, CRI (Color Rendering Index), and power consumption, ensuring our LED products deliver consistent, high-quality light output that meets international performance standards.

Leakage / Ice Bucket Testing

This specialized test simulates real-world exposure to moisture and cold environments, particularly for products used in beverage and bar lighting applications. We verify IP ratings and waterproofing by submerging products in ice water, ensuring no electrical leakage or component failure occurs under wet conditions.

Sound Testing

Conducted in an acoustic chamber, this test measures noise emissions from electronic components and ensures products operate quietly, meeting regulatory standards and providing a superior user experience without unwanted sound interference.

Salt Spray Testing

To validate corrosion resistance, especially for metal components and outdoor/bar-use products, we perform salt spray testing. This accelerates environmental exposure to assess long-term durability against rust and corrosion, ensuring product longevity in humid or coastal environments.

Conditioning Testing

Our temperature and humidity conditioning testing subjects products to extreme environmental cycles (high/low temperature, humidity fluctuations). This simulates global climate conditions to verify product performance and reliability across diverse operating environments.

Packing Transit Testing

We simulate real-world shipping and handling conditions with vibration and drop testing. This ensures our packaging and products can withstand the stresses of global logistics, protecting finished goods from damage during transit and guaranteeing delivery in pristine condition.
