Anonymous users2024-01-23Hello. Astigmatism has nothing to do with night light, and most astigmatism is a congenital problem with the development of the eye. However, astigmatism will not deepen, and astigmatism exceeding 75 degrees (including 75) needs to be solved with glasses, otherwise children can see things clearly and are prone to visual fatigue.

Anonymous users2024-01-21I heard that sleeping with the light on at night reduces the child's immunity, so it is recommended not to use the light.
It does not explode, and the ceramic itself is fired at extremely high temperatures, so it is very resistant to high temperatures.
I don't think I can attract centipedes.
The following people who talk about the bad night light, do you know what "night light" is? From your point of view, it is dangerous to sleep during the day! Because there is such a strong sun hanging in the sky!! >>>More
First of all, look at the power supply with a few volts DC, the power supply is different, and the circuit is different. 3 diodes that emit white light can be connected in parallel or in series. It's up to you to see what you want. See if you have any other requirements for the circuit.
It can't be changed, the power difference is too much, and the resistor-capacitance step-down circuit of 1W is completely different from that of 13W.
