Ordinary plastic deformation and flammability, aluminum tubes must be bright, aviation aluminum.
3, working temperature
When the LED fluorescent lamp is in normal operation, the temperature should be low. Otherwise, the life of the LED light is very short. At the same time, when the energy-saving lamp is lit, rapid flashing or very severe fluctuations indicate that there is a quality problem with the energy-saving lamp. After a few minutes of power-on, there should be a temperature to prove that the heat is good, and the aluminum substrate used for heat dissipation. There is no temperature, it is a fiberglass board, and the heat does not come out.
4, see the startup performance
The startup of the LED fluorescent lamp has a feature: the power is on and it does not flash.
