Light Meters from Spectrum Technologies, Inc.

LIGHT HAS ECONOMIC VALUE: As the driving force for photosynthesis, light is fundamentally important to crop production. Plant growth and development is significantly influenced by both the quantity and the quality of light. Light energy is relevant to other factors too. The ET calculation (evapotranspiration) for irrigation scheduling uses solar radiation as a key variable. Leaf wetness periods or high humidity, which affect disease pressure, can be mitigated with sunny days versus cloudy days. It is essential that growers understand this important variable in order to efficiently produce quality plants.

LightScout DLI 100	FieldScout Red/Far Red Meter	FieldScout Quantum Light Meter
An affordable, first step in measuring light. Measure the light "falling" on your plants! More Information...	Plants use the Red/Far Red light ratio to determine how crowded they are, and grow tall or full accordingly. More Information...	Quantum sensors measure light energy at the specific wavelengths plants actually use for photosynthesis. Start taking more meaningful light level measurements yourself with a low-cost quantum meter.

FieldScout UV Meter	FieldScout Foot-Candle Meter	FieldScout External Light Sensor Meter
Monitor critical UV rays. This meter measures the UV radiation between 250 and 400 nanometers, and is measured in µmol m-2 s-1 (micromoles of photons per square meter second). More Information...	Measure light level in Fc or LUX over three ranges More Information...	This light meter can read any of Spectrum’s light sensors, which come with 6ft/2m cables. More Information...


Multi-Sensor Quantum Light Meter	Greenhouse Weather Tracker
Quantum sensors measure light energy at the specific wavelengths plants actually use for photosynthesis. Gather spatial average PAR readings to measure how much light reaches your plant. More Information...	Measure your plants' most important inputs: light exposure and temperature. Also tracks degree days and chill hour data. More Information...
