As to move light lamp, the beginning is incandescent lamp dimming, energy-saving lamp dimming later (late structure of energy-saving lamp is not suitable for dimming, introduced some styles, are more expensive and stability, even big brands), to its current LED dimming, due to the LED is like incandescent lamp, low voltage will be dark, as bright
Use their phones to test if no stroboscopic, open the camera to the LED light source, the screen flash is no stroboscopic, no flash not; See if it's bright enough, in general, have 4 w is very light, but can meet the above requirements, the basic no problem. The LED is the trend of The Times:
