The Asensetek Lighting Passport LPH spectrometer can measure high power LED Grow lights up to 200,000 lux.  When combined with the Spectrum Genius Agricultural Lighting APP (SGAL) provides the horticultural industry with a professional tool for assessing, selecting and monitoring LED grow lights over time.  More powerfully, integrating this data with plant growth characteristics and analysing over time allows horticulturists to optimise lighting for efficient, healthier plant growth.

  • “Understand” the real needs of plants and produce indoor plants more efficiently
  • Choose the most effective growth lamps
  • Track combined growth and lighting data over time
  • Analyse trends and establish standards for different plant types
  • Optimise time to flower, shoot:root ratio

Spectrum Genius Agricultural Lighting (SGAL) is a professional application for evaluating, selecting, and monitoring LED grow lights and traditional glow lighting to produce indoor plants with higher efficiency.

Use SGAL with your Lighting Passport spectrometer to record and share valuable data and track history. With the Lighting Passport spectrometer, you will improve your growing efficiency and make better LED Grow light management decisions.

  • Smart Diary on Plant Growth

Use the unique “diary mode” function to record light source information and plant growth daily or weekly. Use this information to analyse and efficiently manage your horticultural business.

  • Import Reference Data

Users can import their own plant growth spectral data to the reference library of SGAL APP. The imported spectral data will be shown on the “Reference Menu”.

  • Quick Measurement & Data Analysis

You can either select “Single Mode” to take a swift measurement, or you can choose to run “Multiple Mode” on a series of light sources for comparison and analysis. “Comparison Mode” then allows you to distinguish the differences between two grow light sources.

  • SGAL Reference Generator

“SGAL Reference Generator” is a Macro Excel program. You can import your own plant growth PAR data to the reference library of SGAL APP via this tool.

  • Your all-in-one LED Grow light instrument choice

Traditionally, it requires not only a PAR meter, but a lux meter, a spectrometer, DLI meter, one or two meters for R/ IR, R/ B just to get a complete data for developers to spend more time analysing, comparing, determining optimal LED grow lighting.  The Lighting Passport is all you need!
