Lightmeters

Lightmeters support accurate light measurement for greenhouse, turf, horticulture, research and environmental monitoring workflows where light intensity affects plant growth, quality and site performance.

John Morris Group supplies Spectrum LightScout lightmeters through Spectrum, helping Australian teams source DLI meters, PAR meters, quantum meters, foot-candle meters, UV meters and red/far-red meters for Environmental, Food and Feed and technical measurement applications.

Lightmeters for Greenhouse, Turf and Plant Light Measurement

Lightmeters are used where growers, researchers and facility teams need to measure visible light, PAR, DLI, UV or red/far-red ratios for plant growth and light exposure decisions. The visible category range includes Spectrum LightScout DLI 100 meters for greenhouse and turf use, LightScout quantum and foot-candle meters, UV meters, red/far-red meters, dual solar/electric quantum meters and PAR sensors measuring 400 to 700 nm.

  • DLI measurement: Use DLI meters to calculate daily light integral and compare plant light exposure across greenhouse benches, turf areas or controlled growing environments.
  • PAR monitoring: Select quantum meters and PAR sensors for photosynthetically active radiation measurement across the 400 to 700 nm plant growth range.
  • Foot-candle readings: Choose foot-candle meters where immediate light level readings are required for facility checks, horticulture planning or general illumination comparison.
  • Specialist light checks: Use UV and red/far-red meters where light spectrum quality affects plant development, turf management or research outcomes.

Choosing Spectrum LightScout Lightmeters

Technical buyers should confirm whether the workflow requires DLI, PAR, UV, foot-candle or red/far-red measurement before ordering. Teams should also consider internal or external sensor configuration, solar or electric light source, measurement range, portability, water resistance, data logging needs and whether multiple locations need to be compared at the same time. For related procurement, teams may also review Environmental Measuring Instruments, Temperature Humidity Testers and Weather Stations.

Applications Across Horticulture, Turf and Research

Lightmeters are selected where light levels influence plant health, crop consistency, shade management, lighting design or research data quality.

  • Greenhouse production: Monitor DLI and PAR to optimise natural and supplemental lighting for crop growth and quality.
  • Turf management: Compare light exposure across shaded, open or high-use turf areas to guide maintenance and growth decisions.
  • Controlled environment research: Measure light intensity and spectral conditions in growth rooms, chambers and plant research facilities.
  • Field and environmental monitoring: Support light measurement within broader Environmental and agricultural monitoring workflows.
