The GC 4 was designed as the ideal medium budget/starter LED light for growing in tents up to 80 x 80 cm (~2,5 x 2,5 ft.) - you can switch the spectrum and intensity for three modes: seedling/clone, veg and flower. It replaces a 250 watts HPS/ single-ended/ double-ended light and delivers the same crop yield whilst saving up to 40 per cent in energy. The light spectrum as well as the energy consumption can be adjusted to the respective phase (seedling/clone, vegetative, flower). Four highly efficient full spectrum PAR COB chips are the key components of the lamps. This chip is supplemented by 4 x SMD chips per module. These supply additional blue, red, infrared and near-UV frequencies to support the cultivation of your favourite plants in all phases in a particularly targeted way.
