For many factors and companies, saving energy cost is a big business. With the time goes by, traditional lights are gone, not banned, precisely, but phased out because of the energy cost and pollution. More and more companies and factors require their lighting system to be 20% percent more efficient, at least. And on the other hand, local government requires the enterprise to be more environmental. Most traditional lights are made by halide, not only because emitting toxins but more about its less efficient. Of course, not everyone is interested in next-gen lights. Some of them still wonder why we need them. LED still has shortcomings. They are not cheap. Days of 50$ per LED Street Light s are gone. However, with evolving new technology, they are now more efficient than before. With powerful chips, LED efficacy could reach 80lum/w. it is several times than the Metal Halide lights. May the cost of the LED bulbs is expensive, but you will save more cost on the energy.
