Hydroponic LED Grow Lights

Click here to see our selection of Hydroponic LED Grow Lights.

Since hydroponics can be used almost anywhere to grow healthy plants they are often used with a combination of lights to increase the yield, or for underground or indoor applications. The most advanced lights are hydroponic LED grow lights. LED lights consume much less energy than metal halide or high pressure sodium lights, which used to be the most commonly used indoor plant lights because of their brightness and ability to mimic the suns rays.

Metal halide lights emit light in the blue spectrum, while high pressure sodium emits light more in the red spectrum, closer to natural sunlight. Both spectrums are important for plant growth. Hydroponic LED grow lights can use a combination of red and blue LED lights in one unit so both spectrums can be emitted simultaneously.

Another advantage hydroponic LED grow lights have is that since they are using much less energy than metal halide and high pressure sodium lights they don’t produce as much heat. This is important because if the lights get too hot, they can prematurely dry out a plant, or burn it. Expensive cooling units and fans are not needed nearly as much with LED lights, and the lights can be positioned closer to the plants, which increases their efficiency. LED lights are slowly replacing tradition lights because of the cost that is saved.
