LED grow lights are truly a revolution in the way plants are grown indoors. They have so many advantages. For one thing, they tend to last a very long time, and some come with a guaranteed lifetime in the range between ten and even 15 years. These grow lights are highly energy efficient and promote plant growth in many ways and areas.
In this context, they have a very low heat output and they also have another advantage, and that is that they are very economical. They are also very diverse in nature, because their light is so customizable. Of course the grow lights are not perfect and have their disadvantages, but here's an interesting fact: the attractiveness of these lamps is so wide that even the NASA began using them. A recent breakthrough in the science behind LED grow lights led to the concept of the so-called Solid State Lighting (SSL). SSLs have shown that the capacity of both emit light very close to the visible part of the spectrum. What this means is that the data from light can be used directly or can converge easily when necessary. In addition, you can get free light if you use SSL technology; the usual harmful effects of many light sources are not there. It is here that we return to NASA, the famous Space Center that has started with this SSL technology in space agriculture programs.
When NASA researched on agriculture, its goal ended up being develop artificial light sources that will aid future astronauts be self-sufficient upon landing at colonies through the moon. The key reason why NASA has begun to work with LED lighting technology is as it would be very efficient, cheap and high-tech. This can be unlike fluorescent lamps and incandescent lamps which have been simply not feasible, where energy is anxious; there exists little efficiency with regards to the level of electricity consumed.
