The Evol Grow 650-Si enables you to deliver high-powered, sustainable light to your plants with greater efficiency and flexibility. This linear 650 watt fixture delivers a high PPF of 1,755 µmol/s and a photon or fixture efficiency of 2.7 µmol/J.

The 650-Si is Full Spectrum and has an overall color temperature of 3400K, which improves the radiant energy of red light at 660nm wavelengths in white light. It provides a beautiful working environment and a more realistic color reproduction degree with a CRI level of 90.

The 650-Si features both manual and automatic power adjustment, allowing you to dim the unit from 10% to 100% total power for lower photon intensities without compromising spectrum quality.
