the advantage of LED light:

the LED is a p-n junction on put forward current can emit ultraviolet, visible light and infrared semiconductor solid light-emitting devices. The luminescence mechanism is the core of the p-n junction, when plus forward voltage, the balance of the p-n junction is broken, P the hole of the area into the p-n junction and the original part of the anion, N area electronic into p-n junction and the part of the original positive ions, thus narrow the p-n junction, due to lower the p-n junction electric field of electric field, the decrease of the electronic potential energy, reduce the potential energy is converted into electromagnetic energy, released in the form of photons. Electronic reduce the more power, the higher the photon energy released.

LED semiconductor lighting source has a long service life, high luminous efficiency, small volume, light weight, environmental protection, safe and reliable, and other advantages, also has a significant advantage is due to the leds start voltage and working voltage, LED street light, so there's no need to use ballast. So in saving cost and energy consumption at the same time, also greatly shorten the response time of power.
