The Linshang LS335 is a split-type spectral illuminance meter for comprehensive evaluation of lamps, luminaires, building lighting and horticulture light sources. It measures illuminance, spectrum, correlated color temperature, CRI, SDCM, flicker, UV index, blue-light hazard, temperature and humidity through a responsive 3.5-inch touchscreen.
A dedicated plant-lighting mode adds PPFD, blue/green/red PPFD, YPFD and chlorophyll A/B measurements. This allows one instrument to support conventional lighting audits, LED development and greenhouse or plant-factory optimization.
Key Features
-
Up to 1,000,000Lux: Covers both low-level indoor illumination and high-output outdoor or industrial lighting.
-
Spectral measurement: Displays the 400–700nm spectral curve at 10nm intervals for rapid assessment of full-spectrum LEDs and blue-light content.
-
Core lighting metrics: Measures CCT from 1,000K to 100,000K, CRI, SDCM, flicker frequency and depth, UV index and blue-light hazard ratio.
-
Plant-lighting mode: Measures PPFD and YPFD up to 10,000µmol/m²/s plus blue, green and red PPFD channels and chlorophyll A/B values.
-
Fast response: Measurement response is under 0.7 seconds for efficient multi-point inspection.
-
Digital split probe: In-probe signal processing reduces cable interference and supports accurate remote positioning.
-
Real-time statistics: Displays current, maximum, minimum and average Lux values during measurement.
-
3.5-inch touchscreen: The 480×320 IPS display provides clear access to numerical and spectral results.
-
Data management: Stores 1,000 records and supports batch export through professional PC software.
-
Portable rechargeable design: A 4000mAh lithium battery and automatic power-off support laboratory and field use.
