Sylvania Grolux HPS bulb description

The Sylvania Grolux HPS bulb is a high-pressure, yellowish-sodium light vapor lamp that promotes photosynthesis in plants. Its color temperature is 2050 K, which means it radiates largely in the red color spectrum. This makes it most suitable for use in the flowering stage of plants. The patented curved bulb promotes the highest photosynthetic efficiency. Thanks to the improved external bulb structure, the lamp's performance is exceptionally good. It has been optimized for higher Phytolumen emissions. Its light spectrum maximizes red light emission, which is vital for plant growth, and has exceptional snow retention, delivering 95% performance even towards the end of its life.
