- Q:Why can't the voice switch control the time of the LED bulb?
- The power of LED bulb is much less than that of incandescent lamp, and the control loop and light bulb of simple sound control lamp are connected in series, and the load is different and the time delay is different
- Q:LED bulb w can replace 40W incandescent lamp
- The standard of luminous flux according to the luminaire is lumen (LM). Incandescent lamps are w 11-12lm per 40w=440-480lm
- Q:Led what's the flash of the bulb?
- So, this is the power overheating protection at work. It will not be the case if the outer shell is enlarged or the room is ventilated and the heat should be cooled.
