=The input power minus the power value is the main parameter. The higher the value, the lower the efficiency. It means that a large part of the input power is converted into heat and released; if it is installed in the lamp, it will cause a High temperature, coupled with the heat emitted by a special effect ratio of your LED, will add up to a higher temperature. And the service life of all electronic parts inside your switching power supply is reduced with the increase of temperature. Therefore, high efficiency is the most fundamental factor in determining the service life of the switching power supply. High efficiency cannot be too low, otherwise the heat consumption on the switching power supply is very large. The non-protection type has higher efficiency than the protection type, generally above 80%. However, the high efficiency is related to the pairing and wiring method of the light board.
