Why some remote control switches unable to turn off Energy Saving bulbs?
The energy saving bulbs normally are very sensitive to power, very little power can trigger them to turn on. Refer to the figure above, to derive power, the current needs to need to flow through the bulbs. Without power, the electronic circuit and the receiver can not operate. However, to obtain enough power to run the electronic circuit and receiver, it might trigger the energy saving bulbs to turn on. This makes the mission almost impossible.
