The light meter of lamps is mainly used to measure and evaluate the optical performance of lamps. The specific uses include:

Luminous flux measurement
Measure the total luminous flux (unit: lumen) emitted by the lamp to evaluate its overall luminous ability.

Illuminance measurement
Measure the illuminance (unit: lux) generated by the lamp on a specific surface to evaluate the lighting effect.

Light intensity distribution measurement
Measure the light intensity distribution of the lamp in different directions, draw the light distribution curve, and evaluate the uniformity and directionality of the light beam.

Color temperature measurement
Measure the color temperature of the lamp (unit: Kelvin) to evaluate the warm and cold tones of the light source.

Color rendering index measurement
Measure the color rendering index (CRI) of the lamp to evaluate its ability to restore the true color of the object.

Luminous efficiency measurement
Calculate the luminous efficiency of the lamp (unit: lumen/watt) to evaluate its energy conversion efficiency.

Flicker measurement
Detect the flicker of the lamp and evaluate its impact on visual health.

Spectral analysis
Analyze the spectral distribution of the lamp to evaluate its color performance and applicable scenarios.

Light decay measurement
Measure the luminous flux decay of lamps after a period of use to evaluate their lifespan and performance stability.

Quality control
Used for quality inspection in production to ensure that products meet design standards.

Lighting design verification
Verify whether the lighting design achieves the expected effect and optimize the lighting solution.

Energy efficiency evaluation
Evaluate the energy efficiency level of lamps to help choose energy-saving products.
