What's the difference between incandescent frosted and non-frosted? Will incandescent frosting with the same power be brighter?
When the frosted bulb is lit, the light will be dim, because the glass of the bulb is opaque, as you can see from the picture.
Incandescent lamps and energy-saving lamps can generally be installed in the same lamp holder, because the lamp holders of ordinary incandescent lamps and energy-saving lamps are E27.
