Why don't leds and light bulbs adjust brightness by dimming switches
LED fluorescent lamp screen is the power supply failure in the lamp tube, the power transformer circuit has a problem. Fluorescent lamp flash screen. It may be that the regenerator is too long and the tube is too old to light up
Dimmer switch is to adjust the output voltage, output voltage continuous variation between 0 ~ 220 v, but LED and lamp only between 180 v and 220 v to normal light, less than 180 v is not bright, so the light. The fluorescent light bulb is connected to the power supply quality of the grid, and cannot solve it.
A flash is a period of time and a period of time. In a second, the human eye is not able to see more than 60 times, and can see the frequency of the flash, indicating that the fluorescent lamp is not always bright, but has the time of extinction.
There is something that can be supported, usually for a price that is inexpensive, because the traditional ones don't do the dimming
