Lumatek full spectrum Attis LEDs balance light quality (spectra) with light quantity (intensity and duration) sufficient to provide single-source lighting for entire grow cycle from vegetative through flowering period. This will reflect at the end of the grow cycle with hgiher quality and quantity of produce. The higher specification Lumatek Attis LEDs are fixtures are ideal for use as supplemental light or as the sole light for the whole growth cycle, they produce very high PPF and Photon Efficacy (fixture efficiency). The array of LEDs create a uniform spread of light at short distance to the crop enabling single source grow lighting for multi-layer cultivation systems, single benches in low rooms and grow tents. Benefits Very High PPF and Phton Efficacy; Low maintenace, solid state unit; Osram and Lumileds diodes; Dimmable, Can be controlled with any 0-10V LED controllers Technical Specifications ZEUS ATTIS 200W Efficacy: 2.3 µmol/J PPF: 460 µmol/s ZEUS ATTIS 300W Efficacy: 2.3 µmol/J PPF: 690 µmol/s
