At 336 Watts, the fSpectrum system brings an impressive number of photons to the plant canopy. The photon flux (PPF) of 940 μmol/s (2.8 μmol/J) provides high light intensities onto your plants and ensures high photosynthesis rates.

The fSpectrum LED is the choice for growers who need a powerful, energy-efficient, spectrum adjustable, waterproof LED grow light that delivers even and high PPFD onto and deep into the canopy.

HIGH EFFICIENCY LED GROW LIGHT

MARKET-LEADING

Crafted from a superb piece of aluminum, the aerodynamic design of the fSpectrum primarily serves as a passive cooling mechanism. 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. Our world-class grow lights are the choice for professional growers who look for high yields at the lowest cost of operation.​

SEED TO HARVEST

FULL SPECTRUM

A power button ignites the powerful and vitalising light spectrum which applies to all plant species and in all growth cycles. 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.
