Luminance Meter Frequently Asked Questions
Q: What is the difference between a Luminance meter and an illuminance meter?
A: A Luminance meter measures the brightness of light emitted or reflected from a surface (cd/m²), while an illuminance meter measures the amount of light falling on a surface (lux). The Luminance meter evaluates how bright the light source appears to the human eye, making it essential for display quality assessment and lighting design applications.
Q: How often should I calibrate my Luminance meter?
A: We recommend calibrating your Luminance meter annually for most professional applications. However, for critical measurement tasks or regulatory compliance, more frequent calibration (every 6 months) may be necessary. The meter includes a calibration certificate traceable to national standards, and our calibration service ensures your device maintains its specified accuracy throughout its service life.
Q: Can the Luminance meter measure flicker in LED lighting?
A: Yes, our advanced Luminance meter models include flicker measurement capability with a sampling rate up to 20,000 times per second. This feature allows you to quantify flicker percentage and frequency in LED lighting systems, helping identify potential issues in PWM-controlled lighting that might cause eye strain or other health concerns.

Additional FAQ Section
Q: What is the typical response time of this Luminance meter?
A: Our Luminance meter offers adjustable response times ranging from 0.5 to 5 seconds. The fast response mode (0.5s) is ideal for dynamic measurements, while slower settings provide more stable readings for static light sources. The device automatically compensates for rapid changes in luminance while maintaining measurement accuracy.
Q: Can I measure LED screens with this Luminance meter?
A: Absolutely. Our Luminance meter is particularly well-suited for measuring LED displays, OLED screens, and other emissive technologies. The device's spectral response closely matches human vision, and optional narrow-angle lenses allow precise measurement of individual pixels or small screen areas. For OLED measurements, we recommend using the low-light sensitivity mode for optimal results.
Q: Does the Luminance meter come with measurement software?
A: Yes, the Luminance meter package includes our professional measurement software suite compatible with Windows and macOS. The software enables advanced data analysis, report generation, and real-time monitoring. Features include customizable dashboards, statistical analysis tools, and export options for common formats (CSV, PDF, etc.). Regular software updates are provided to our registered users at no additional cost.
