Lamp power if you do not do is the failure of the lamp, as well as the power when the voltage supplied to poor contact can also cause damage to the lamp beads, when the surge voltage can not be ignored, because at this time can reach kV high-voltage transient above, we can use some of the high sensitivity of the convex wave absorber to measure (varistor), in front of the fuse will be ringing off the hook, its in the case of inductive load is sensitive.

Some people say that electrolysis life is to determine the power of life, this claim is unfounded, our previous TV is an example, with 20 years is not a problem, general electrolysis bad proportion is very small, less than 1%. Electrolytic then 2000 hours is best, GU10
