Compact and Powerful

Crafted from a superb piece of aluminum, the aerodynamic design of the fSpectrum primarily serves as a passive cooling mechanism. A power button ignites the powerful and vitalising light spectrum which applies to all plant species and in all growth cycles. The fSpectrum is one of the most efficient lighting systems on the market, producing 35% more plant-beneficial light per watt than high-pressure sodium (HPS) while generating less than 60% heat.


High Performance

With only 84 Watts, the fSpectrum system brings an impressive number of photons to the plant canopy. The photon flux (PPF) of 235 μmol/s (> 2.8 PPF / Watt) provides high light intensities on the recommended illumination surface and ensures high photosynthesis rates.


Lighting Control (optional)

The fSpectrum series can be controlled by several industrial standard protocols (DALI, 0-10V, PWM), allowing to schedule a gentle morning rise and sun-dawn of light intensity - for minimal light stress and maximum savings.


Made in Switzerland

Made only from the finest components, the fSpectrum is a secure investment and guarantees long and maintenance-free operation. Our products are manufactured in Switzerland, where no compromises are made to the detriment of quality and efficiency.


100% Coverage

The arrangement of several fSpectrum modules above the plant canopy ensures a uniform as well as diffuse and shadow-free illumination. The result is homogeneous growth as well as even nutrient and water uptake: for optimum control and consistently high yields.


Grow Smart

Our grow lights contribute to energy cost savings of more than 60%. Compared to conventional luminaries, our systems generate more PAR and produce less heat, all with a longer service life and without the use of highly toxic chemicals.


3 Years Warranty

Even after 60.000 hours or 6 years of continuous operation, the luminosity of the iSpectrum will maintain up to 80%. The iSpectrum runs practically maintenance-free and the replacement of bulbs is a thing of the past, which is why we offer a 3-year warranty.


The wide-banded output spectrum is perfectly suitable to all plant species from seed to harvest, where the spectral distribution follows the curve of the relative quantum efficiency of McCree (1972). The uncompromising intensity of the warm white light provides a balanced mix of all spectral colours for strong stem formation and bushy growth with short internodal spacing in the vegetative phase and sturdy fruiting branches with high yields in the generative phase.
