Anonymous users2024-01-24They replied that the LED is more power-saving than the bulb, but in fact, our night light is now not using a bulb, but using a low-power fluorescent tube, and the night light is generally driven by LED resistance step-down, although the LED itself is power-saving, but the electricity is consumed on the resistor, so in general it is not power-saving. However, some use resistor-capacitance and decompression, which is much better, so the purchase should be clear.

According to the law of conservation of energy.
Energy can be transferred from one object to another, and the forms of energy can also be converted into each other, but the energy never disappears. This is how people summarize energy, which is called the law of conservation of energy. >>>More
The night light has no electromagnetic radiation, because its power is extremely low, and it is also light radiation, and it is luminous and has light radiation, not too strong light radiation, and it is not harmful to people.
Generally, the night light will not affect the baby's development, as long as it is not too bright, it can be installed in a place that is not very obvious, you can see a little light and you can, avoid bright light directly irradiating the baby's face and eyes, there will be no problem, the usual degree is not too high, and the child should not be too nervous, relax.
If it is the power that is truly marked, of course, it is a power saving with a small number.
Philips LED Night Light There are: Philips LED Night Light Yellow Philips LED Night Light Pink Philips LED Night Light Blue, three styles. >>>More
