They are a wonderful replacement for the technologies of the past, such as metal halide and mercury vapor. It’s been documented in university studies that growing plants with white light spectrum, like the spectrum produced by modern LED grow lights, is superior to using red and blue light wavelengths alone. One of the biggest advantages to growing with LEDs as compared to growing with High-Intensity Discharge (HID) bulbs like High-Pressure Sodium (HPS) and Metal Halide (MH) bulbs is that LEDs consume a fraction of the electricity of an HPS or MH bulb. Metal halide bulbs, sometimes shortened to just “MH” and high pressure sodium bulbs, sometimes shortened to simply “HPS”, are in a family called High Intensity Discharge bulbs, or “HID” for short.
