Q:The difference between LED light band and T5 tube

LED which are the advantages of the _Led tube and tube?1: environmental protection lamps, the traditional fluorescent lamp contains a large amount of mercury vapor, if broken, mercury vapor will evaporate into the atmosphere. But the LED tube doesn't use mercury at all, and LED products don't contain lead. They protect the environment. LED lights are generally recognized as "green lighting" in twenty-first Century.2: less heat, the traditional lamps will produce a lot of heat, and LED lamps are all the power conversion to light energy, will not cause waste of energy. And the documents, clothes will not fade.3: no noise, LED lamps will not produce noise, for the use of precision electronic instruments for the occasion of the good choice. Suitable for libraries, offices and other occasions.4: eye protection traditional fluorescent lamp using AC, it will have 100-120 times per second strobe. LED lamp with LED constant current, is the direct conversion of AC to DC, reducing LED decay, quick start, no flicker, protect the eyes.5: no mosquitoes worry, LED tube will not produce ultraviolet light, infrared radiation, mercury and other harmful substances do not exist,
