The installation and use of specific steps LED Light Bars are as follows: A, light support no rectifier in again when in 220 V ac, will be installed in fluorescent tubes LED lighting fixtures inside, turning to shine LED fluorescent tubes and adjust good luminous direction; Second, there were inductance rectifier fixtures, short sub or dismantled rectifier, pulled out and the brightness, will be installed in lighting lamp in turn LED to shine fluorescent tubes and adjust good luminous direction; There were three, light support electronic rectifier, demolished rectifier, will be installed in lighting lamp in turn LED to shine fluorescent tubes and adjust good luminous direction; 1, flexible led strip of fluorescent lamp size and common fluorescent lamp installation size. 2, the LED fluorescent lamp on both ends of the needle in the tube is touch together, against the 220 V are respectively in the same, then pick up the two needles the touch, or LED light sun burn out. 3 in energy saving transformation, if only out for KaiYuan constantly and brightness and ballast, LED fluorescent lamp can also bright, but will seriously affect LED the life of fluorescent lamp, at about 3000 hours LED fluorescent lamp will attenuation 50%! This kind of situation not of replacement range. If the electronic ballast is ballast burn down! 4, led strip lights it is strictly prohibited to frequent switch, 10 seconds to switch frequency not more than 2 times.
