LED Fade Meters
Indoor Environment Testing Under LED Lighting | Temperature & Humidity Control
Simulate real indoor environments with LED lighting, temperature, and humidity control. Ideal for material durability and lightfastness testing.
Indoor Environment Testing Under LED Lighting
Reproduce Real Indoor Conditions with Precision
Products used in modern indoor environments are constantly exposed to LED lighting, temperature variations, and humidity. These conditions can significantly affect material durability, color stability, and overall product performance. As global regulations on mercury—such as those under the Minamata Convention on Mercury—continue to tighten, along with increasing demand for energy efficiency and longer product lifecycles, LED lighting is rapidly becoming the standard in indoor environments. Our advanced testing solution is designed to accurately reproduce these real-world indoor conditions by combining LED lighting with precise temperature and humidity control. This enables reliable evaluation of material behavior under today’s evolving indoor environments.
LED Fade Meter LF-Z
3 Key Features
- One Unit, Multiple Light Sources
- By changing the light source, it is able to test two types of white LEDs, cool white LED and warm white LED*. Since the light source is unitized, it can be easily changed. A white fluorescent lamp unit is also available.
- Illumination 35,000 to 70,000 lx
- Illuminance on the specimen surface can be precisely adjusted from 35,000 to 70,000 lx using an integrated controller, for a wide range of LED lighting conditions, including cool white LED, daylight LED, warm white LED, neutral white LED, and full spectrum LED.
- Indoor Environment Simulation
- In addition to LED lighting, precise control of temperature and humidity makes it ideal for accurately reproducing indoor environments.
