Lightmeters

Lightmeters support New Zealand 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 NZ 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 New Zealand Greenhouse and Turf Workflows

Lightmeters are used where growers, researchers and technical teams need to measure visible light, PAR, DLI, UV or red/far-red ratios for plant growth and light exposure decisions. The visible 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 monitoring: Use DLI meters to calculate daily light integral and compare plant light exposure across greenhouse, nursery or turf locations.
  • PAR measurement: Select quantum meters and PAR sensors where photosynthetically active radiation needs to be measured for plant growth decisions.
  • Foot-candle checks: Choose foot-candle meters where immediate light readings are needed for facility, horticulture or site comparison work.
  • Spectrum-specific testing: Use UV and red/far-red meters where light quality affects plant response, turf condition or research outcomes.

How to Choose Spectrum LightScout Lightmeters

Before ordering, technical buyers should confirm whether the application requires DLI, PAR, UV, foot-candle or red/far-red measurement. Teams should also check sensor configuration, solar or electric light source, measurement range, portability, water resistance, field use requirements and whether multiple locations need to be compared. Related procurement may include Environmental Measuring Instruments, Temperature Humidity Testers and Weather Stations.

Applications Across NZ Horticulture, Turf and Research

  • Greenhouse production: Monitor PAR and DLI to optimise light exposure for crop growth, supplemental lighting and production consistency.
  • Turf management: Compare light levels across shaded, open or high-use turf areas to support maintenance decisions.
  • Plant research: Measure light intensity and spectrum conditions in growth rooms, chambers and controlled environment studies.
  • Environmental and agricultural monitoring: Support light measurement as part of broader Environmental and field monitoring workflows.

Supported Brand and Related Categories

The visible category range is led by Spectrum, covering LightScout DLI meters, quantum meters, UV meters, red/far-red meters, foot-candle meters and PAR sensors for plant-focused light measurement. NZ procurement teams may also review Measuring and Observing and Testing Instruments and broader Laboratory and Scientific Equipment.
