Grow lights are designed to promote plant growth. They emit an electromagnetic spectrum which is appropriate for photosynthesis. Classified by light sources, there are Incandescent, Fluorescent, Metal-Halide (MH) HID, High-pressure sodium lamps and LED grow lights in the market. Because of LED technology progress recently, LED grow lights are attractive to indoor and outdoor growers since they do not consume as much power, do not require ballasts, produce a fraction of the heat of HID lamps and long lifespan. If you are looking for grow lights, you may take LED grow lights into consideration because of the following features.

1. High Efficiency

95% energy of LEDs can be absorbed by plants, but only 10% by HPS or MHS. LED can produce the blue and red wavelengths which can be best used in photosynthesis. We can control the wavelengths from LED and make use of power efficiently.

2. Low Power Consumption

Because 95% energy of LEDs can be absorbed by plants. It saves 70% to 90% in energy consumption compared to fluorescent tubes, HPS or MHS. LED is famous for high power efficiency. Nowadays the power efficiency is more than 100lm/w and is improved rapidly.

3. Long Lifespan

The lifespan of LED is more than 50,000 hours. HPS lamp is about 3,000 - 5,000 hours.

4. Minimal Heat

LED grow lights are warm to touch. It does not scorch young or tender plants like HID lighting can. It also reduces your room/building air conditioning costs.

5. Versatile

Blue LED can be easily added to enhance vegetative growth and red LED can be used to promote the fruiting and flowering stage.

So if you are looking for grow lights, I believe that LED grow lights are your good choice.
