How long will the nail lamp age?

The LED lamp beads in the nail lamp have a lifespan. Ordinary lamp beads start to decay after 3000-5000 times of use. Export-grade lamp beads used for 5000–7000 cycles will also start to decay. After attenuation, the brightness visible to the naked eye does not decrease, but the emitted ultraviolet energy will become very low, and it will not even dry your nail polish. So some people may wonder why the nail polish glue that was very strong suddenly became weak. Is there something wrong with the glue? In fact, there is a problem with the lamp. Generally, there are four lamps in a nail lamp, or 9 W pieces; please replace the lamps regularly, every 6 months, so as to maintain the best effect.
