The LED lamp and built-in ballast which good
Or one light is said to be a power of good, the LED lights can be normal in 3 years or so, that the life of the power supply is a year or so, my shop is also made out of the blue light,
I sleep standing still with a good outside. I was for my own use outside. I don't think inside is broken is not repaired? I now use is out of the blue card
LED to shoot the light is better than with ballast lamp. LED to shoot the light small power consumption, high brightness, long life, less heat, its driver USES the way ChengHeng current source power supply switch power supply, small volume, high efficiency, low noise, is a new energy-saving products. And built-in ballast product, are generally not fluorescent lamp, most use inductive ballast (now also has a switch power is applied to make ballast, but the volume is bigger than the LED constant current source), ballast itself than switch power supply, power consumption is easy to produce power supply hum. Lights glowing on the filament heating, heat.
