Lumatek full spectrum Zeus 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 higher quality and quantity of produce. The higher specification Lumatek Zeus LEDs are linear multi-light bar fixture producing 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 maintenance, solid state unit; Osram and Lumileds diodes; Dimmable, Can be controlled with any 0-10V LED controllers Technical Specifications ZEUS COMPACT PRO 465W Efficacy: 2.7 µmol/J PPF: 1256 µmol/s ZEUS COMPACT 465W Efficacy: 2.3 µmol/J PPF: 1070 µmol/s ZEUS 600W Efficacy: 2.3 µmol/J PPF: 1380 µmol/s ZEUS PRO 600W Efficacy: 2.7 µmol/J PPF: 1620 µmol/s
