Does the incandescent lamp have no eye protection?
And high-frequency non-frequency energy-saving lamps can overcome this phenomenon!
Incandescent or fluorescent lamp with an inductance ballast on the presence of 100Hz strobe
At this time to show the phenomenon of light intensity change called strobe
The curve is open to the approximate parabolic graph, which is almost imperceptible at 40Hz
The human visual system is most sensitive to light intensity at 8.8 Hz
