There are many types of artificial lights that have evolved in the process since long, to help expand the green houses. The different types of these lamps include High Pressure Sodium (HPS) Lamps, Incandescent Grow Lights, LED Grow Lights and Metal Halide Lamps. While many or all of them have been popular at one point of time and are still used today to some extent, LED Grow Lights are the highly preferred lamps since the day they were introduced.

The reason for its high demand and wide use can be easily and well justified by many of its positive aspects that are also its strong points. Let us see some of the major strengths of these LED Grow Lights now.

1. Cost Effective - The cost of these LED Grow Lights are very cheap, so initial investment is too low. Apart from this there are many such aspects that add to its cost effectiveness, directly and indirectly.

> Easy to install - They do not require any specific structure to mount it upon. They can be easily hung down from any of the existing structures.

> Less Energy Consumption - Many evidences say that the amount of energy used by these LED Grow Lights is somewhere below 50% than any other such lamps.

> No Coolers Required - They produce only the required amount of light and emanate heat much below the desired level only. Hence, there is no requirement for high cost coolers to be invested upon to cool the atmosphere around the plants. This saves initial investment as well as extra energy consumption for the coolers.

> No Ballasts Required - They do not require any supporting ballasts. This has not only double benefit of saving cost by way of investment as well as energy cost but also is advantageous in another way. And that is the unbeatable fact that the environment is peaceful and noiseless, because as you know ballasts produce immense and irritating sound.

2. Highly Efficient - Its non production of heat makes it more efficient as it can be placed at a close distance to the plants peak point from where it absorbs the light. This ensures that the lights fall directly on these plants and all of it is absorbed without any wastage by way of falling at unwanted places where it will not be absorbed.

3. Lasts Longer - These LED Grow Lights have been proved to go on and on and on for a much longer period than normal ones. They have proved that they last for a minimum of 7-8 years even if they are used on a daily basis. This is simply superb, isn't it?

4. No Maintenance - These lamps are so manufactured that they require no maintenance. All that we need to do is buy it, hang it out and start using and simply forget about it.
