Introduction
A lux meter, also known as an illuminance meter or light meter, is an instrument used to measure the illuminance, which is the amount of light falling on a surface, expressed in lux, and it is used in lighting design, photography, workplaces, agriculture, and many other applications. The lux meter consists of a light sensor, typically a silicon photodiode with a filter that approximates the spectral response of the human eye, and a display that shows the illuminance value; the sensor is placed on the surface to be measured, and the meter measures the incident light and displays the illuminance in lux, and it is used to measure the illuminance from natural and artificial light sources, and it may include features such as data logging, a hold function, and different measurement ranges, and it is available as a handheld portable instrument. Lux meters are used in lighting design and installation for measuring and verifying the illuminance in rooms, offices, and public spaces, for checking that workplaces meet the illuminance requirements for safety and comfort, for optimizing lighting in greenhouses and plant growth facilities, for photography and cinematography for setting the exposure, for museums and galleries for controlling the light on exhibits, for checking the uniformity of lighting, for energy audits, for research, and for many other applications, and they are used by lighting engineers, facility managers, photographers, growers, and safety professionals. With their measurement of illuminance, lux meters are essential instruments for lighting measurement and design.

FAQ
Q1: What testing scenarios is this meter mainly applied to?
A: The lux meter is used in occupational health and safety, industrial facilities, architectural lighting, agriculture (greenhouse, livestock), research, quality control, photography and film to measure illuminance (light intensity) in lux (lumens per square meter) or foot-candles for lighting design, workplace safety, quality control and research. It supports workplace lighting assessment for occupational health and safety compliance, industrial facility lighting measurement, architectural lighting design and verification, greenhouse and livestock lighting management, research light level measurement, quality control lighting inspection, photography/film lighting setup, and energy efficiency lighting assessment. Illuminance measurement is essential for ensuring adequate lighting for safety, productivity, plant growth and regulatory compliance across multiple applications.
Q2: What standards does the meter comply with?
A: The lux meter follows relevant ISO, CIE, ASTM and GB/T standards for light measurement, including CIE 121 for photometry, ISO/CIE 19476 for illuminance meters, JJG 245 (Chinese metrology), and relevant occupational lighting standards (GB 50034 for building lighting, GBZ 1 for occupational health). The hardware complies with IEC 61010 safety standards. Calibration should be traceable to national/international standards (SI lux). The sensor should have CIE photopic response (V(lambda) function) per CIE standards.
Q3: What is the warranty period for the whole meter and key components?
A: The whole lux meter is covered by a 12-month warranty. The light sensor, electronics, display and housing are covered, while batteries, protective case and fuses are consumables or accessories. Damage from improper use, dropping, sensor damage or unauthorized repair is excluded. Extended warranty may be available for precision models.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation is simple: power on, place sensor at measurement point, wait for stabilization, and read result. No professional training is required for basic use, but for precision or regulated applications, users should follow proper measurement technique, calibration and documentation. We provide an operation manual and remote guidance. Proper sensor placement (cosine correction, no shadow) is important for accurate readings.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibration recommended every 6-12 months for precision/regulated use, or per quality system requirements. Routine verification against a reference light source periodically. Battery replacement when needed. Sensor condition checked (clean, no scratches). Full meter calibration annually by qualified personnel for critical applications.
Q7: Are supporting consumables universal?
A: Batteries, protective cases and calibration services are available from general suppliers. Long-term consumable cost is very low for a lux meter.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes measurement range, accuracy class, sensor type (cosine-corrected, silicon photodiode), display, data logging, connectivity, units (lux, fc, W/m2) and accessories. Additional sensors, cases and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: No installation is required for portable lux meters. The package includes the lux meter, sensor, calibration certificate and instruction manual. On-site training is available at additional cost for occupational lighting assessment.
Q10: What types of applications are compatible with this equipment?
A: The lux meter measures illuminance in indoor and outdoor environments including workplaces, industrial facilities, buildings, greenhouses, laboratories, stages and other locations within the measurement range and specification. Different applications require specific measurement techniques: workplace lighting (measure at work surface height, multiple points), outdoor daylight (measure horizontal/vertical), greenhouse (measure at plant canopy level), stage lighting (measure at performance area). The sensor should have proper cosine correction for accurate measurement at various angles. Users should place the sensor properly (flat, at measurement plane, no shadow from operator or objects), allow sufficient stabilization time, calibrate regularly with traceable standards, avoid exposing the sensor to direct sunlight beyond its range, use proper measurement geometry per standard (e.g., GB 50034 for building lighting), report results in lux (or foot-candles) with measurement location and conditions specified, and for regulatory compliance, follow applicable lighting standards (occupational: GBZ 1, building: GB 50034). The sensor should be kept clean (dust, fingerprints affect readings) and handled carefully (avoid dropping, scratching the sensor). For outdoor use, use a weatherproof meter or protect the sensor. For UV measurement, use a separate UV meter (lux meters measure visible light only). For LED lighting, ensure the meter has proper spectral response (some low-cost meters may not accurately measure LED spectra). For precision measurements, use a meter with class A or B accuracy per CIE/ISO standards. The meter should be stored in a cool, dry place with the sensor protected. For energy efficiency audits, measure illuminance alongside power consumption for lighting efficacy assessment. The lux meter should not be used in environments with excessive temperature, humidity or electromagnetic interference unless rated for such conditions.
