How to tell the difference between the stage shaking lights?
The method of distinguishing the stage jitter lamp is as follows:

Look at the overall "power factor of the lamp": the low power factor indicates that the driving power supply and circuit design used are not good, which will greatly reduce the service life of the lamp. If the power factor is low, the lamp with good bulb will not last long.

See "Heat dissipation conditions of lamps-materials and structures": heat dissipation of lamps is also very important. If the lamp with the same power factor and the lamp bead with the same quality have poor heat dissipation conditions, the lamp bead will work at high temperature, the light attenuation will be great, and the service life of the lamp will be shortened.

Looking at the driving power supply used by lamps, the service life of power supply is much shorter than that of other parts of lamps. The service life of power supply affects the overall service life of lamps. The theoretical life of lamp beads is 500-65438+10,000 hours, and the life of power supply is 0.2-30,000 hours. The design and material selection of power supply will determine the service life of power supply.

See if it meets the safety standards. Safety standards for lamps have been promulgated. Please select lamps according to national safety standards.
