It depends on the wattage of your energy-saving lamps W, and how many hours your "night" is.
In this way, W*H 1000 is the degree of your energy-saving lamp burned overnight.
The electronic switch is not easy to use, yes, it is often broken, it is recommended that you change the switch control.
Check whether there is a problem with the power supply voltage, whether there is a loose connection in the line, whether there is a problem with the lamp holder, and try to replace the lamp with good quality.
The white light uses 3-5W energy-saving lamps The warm light uses 5-7W energy-saving lamps, the tubes are spiral-shaped, which looks better than the U-shape, and even has the form of candle bulbs (but the power needs to be increased), and the most energy-saving is to choose LED energy-saving lamps.
One by one, either downlights or spotlights. Downlights are astigmatism, and spotlights are spotlights (generally used for displays, or partially prominent scenes).
3W refers to power consumption, not to the brightness, the luminous efficiency of energy saving is higher than that of the night light, so the energy-saving light of the same wattage will be much brighter than the night light.
