Horticultural Light Measurement | GL Spectis 1.0 Touch

Optimise Your Operations

Electromagnetic radiation in light visible to the human eye (within the spectral range 380-780nm) is actively used in plant photosynthesis, known as Photosynthetic Active Radiation (PAR). However, it is important to understand that visible ‘brightness’ does not effectively support the photosynthesis process. To optimise lighting for horticultural applications you must provide enough radiation from a specific wavelength(s) at the right time to effectively maximise yields. Using Lux, CCT or other vision related metrics to verify or quantify lighting for plants is incorrect and often leads to ineffective results.

There are many different PAR meters and other radiometers available on market however the majority of them are designed and preconfigured for continuum day light spectra. For horticulture LED lighting, only properly calibrated and high-quality instruments can provide dependable data for professional users.

Measure. Improve. Grow

We deliver more than just high performance PAR meters. Expand your capabilities with the Spectrosoft Analysis Software Interface which helps to evaluate all radiometric and active radiation data required for accurate horticulture light measurement. Speak to a Sales Specialist for more details.

One System. All Metrics

Our comprehensive measurement systems support PAR, PPFD and PBAR measurement in addition to spectral and colour-metric quantities. If required, different probes and integrating spheres can be connected to calibrated spectroradiometers for professional horticulture light measurement.

Faster, Better Results

Our pre-configured horticulture light measurement systems help you to quickly and accurately measure LED growing lights. Carefully calibrated devices ensure you get dependable data to enable you to make correct, informed decisions on how to optimise lighting for plant growth.

What Can You Measure?

 

Photosynthetic Active Radiation (PAR) and Photosynthetic Photon Flux Density (PPFD)

For plant growers, biologists and scientists the most important data in the light requirements for plants is PPFD measurement (Photosynthetic Photon Flux Density). PPFD is a measure of the amount of light that actually reaches a plant. It can be described as the number of photosynthetically active photons that fall on a given surface each second.

The measurement of light which stimulates plant growth includes the PAR spectra and is expressed in PPFD values in μmol/m2/s and PPF in μmol/s. Similar to human vision metrics where we are evaluating Lux and CRI, which is the amount of light and the quality of light for visibility, for plants we are using PAR and PPFD to evaluate the amount and quality of active radiation.

Photosynthetic Photon Flux PPF (PPF)

For manufacturers of growing lights, PPF measurement is an important metric. This evaluates the total amount of energy that is produced by a light source per second. It is similar to radiant power measurement and it can be made with an integrating sphere connected to spectroradiometer when the system is properly calibrated, and the photosynthetic photon flux calculation is supported by the software. We offer a complete range of integrating spheres which are ready for PPF measurement at sizes ranging from 48mm up to 2m.

For laboratory applications, we recommend the Spectis 5.0 Touch PAR/PPFD meter which offers a higher resolution detector and extended spectral range. The correct equipment for PPF measurements is the GL Opti Sphere – available in 48mm up to 2m diameter. We also provide compatible laboratory grade software for effective data analysis, comparison and reporting.

Plant Biologically Active Radiation (PBAR)

PBAR is a relatively new metric that is becoming more popular as it covers extended wavelengths from 350 to 800 nanometres in the spectrum (i.e. PBAR Flux). This metric recognises that photopigments, other than chlorophyll, that are sensitive to a wider range of wavelengths have been discovered in plants. For this reason, an extended spectral range measurement system is suggested.
