Spectral Efficacy Calculator

Accurately assessing your plants spectral requirements can be tricky with all the different light types and output specifications on the market we have white, mono mixes, phosphor , quantum dot and white mono mix led lamps on the market all with different spectrums.

Its not easy comparing a spectrum on the side of a box to your chosen plant absorption curves and then there is still no good answer as to how efficient the spectrum of your lamp is for your chosen absorption curves.

We like to be efficient and we like to give our customers exacting and precise information about our lamps and so we wrote software to accurately assess spectral efficacy and to produce informative and precise spectral charts.

This makes it very easy for the grower to know if the needs of their plants are being met by their lamp spectrum.
