LS330 spectral Illuminance Meter is a versatile instrument designed with a spectral sensor. It is used for measuring illuminance, UV index, flicker frequency, standard deviation of color matching (SDCM), color rendering index (CRI), correlated color temperature (CCT), blue light hazard ratio, temperature, and humidity in various scenarios such as lamps and lanterns lighting, outdoor lighting, greenhouse lighting, and stage lighting. The instrument also can display the spectral curve, which helps identify the type of lighting fixture.The instrument also has a plant illumination mode, which is specially designed for plant growth environments. It can accurately measurephotosynthetic photon flux density(PPFD), PPFD (Blue), PPFD (Green), PPFD (Red), Yield Photon Flux Density (YPFD), chlorophyll-a, and chlorophyll-b, helping users understand and optimize light management during the planting process and improve plant growth efficiency. It is suitable for home gardening, plant factories, greenhouses, agricultural research, plant lighting, and other fields.

In normal mode, the instrument measures parameters like illumination, CCT, flicker frequency, UV index, SDCM, CRI, temperature, and humidity to evaluate lighting characteristics. In plant mode, it accurately measures PPFD, YPFD, chlorophyll-a, and chlorophyll-b to optimize plant lighting for better quality and yield.
The instrument offers both normal and plant illumination modes, meeting diverse measurement needs. It handles both everyday lighting detection and plant growth parameters (e.g., PPFD, chlorophyll content), helping users optimize lighting in various scenarios.
The instrument is designed with a spectral sensor, and the spectral response matches the V(λ) function. This ensures accurate measurement precision.
The instrument has a spectral curve measurement function, which can view the light intensity and distribution at different wavelengths, identify whether the light source has spectral missing and detect whether it has blue light protection.
Ultra-large range design, range up to 1 million Lux, both strong and dim light can be measured accurately.
The instrument features a flicker measurement function, can evaluate whether lighting meets requirements based on flicker frequency and percent flicker. This provides reference for sales and R&D of lighting.
The instrument measures correlated color temperature, aiding lighting manufacturers in fixture development and lighting design.
The instrument has CRI and SDCM measurement function, clearly showing the difference between the testing light source and the standard light source.
The blue light hazard ratio can be displayed to objectively evaluate the blue light hazard of the lighting source.
(The blue light hazard ratio is the ratio of the blue light hazard to the corresponding radiation amount. The larger the ratio, the greater the proportion of blue light.)
The instrument can accurately measure photosynthetic photon flux density (PPFD), yield photon flux density (YPFD) and chlorophyll content, providing comprehensive data support to help optimize plant light intensity, distribution and health status, and improve growth and yield.
