How often should the UV lamps in a UV gel nail drying lamp be replaced?

The core component of a UV gel nail drying lamp is its UV lamp, whose performance directly impacts the efficiency and quality of gel curing. While these lamps are durable, the phosphor and mercury vapor within them gradually degrade with use, resulting in a decrease in UV output intensity. We recommend replacing the lamps after 200 to 300 hours of use. For high-frequency nail salons, this may mean replacement every 6 to 12 months. For home UV gel nail drying lamps, which are less frequently used, the replacement interval can be extended to 1-2 years, but actual efficiency should still be considered.

The key to determining whether a UV gel nail drying lamp lamp needs replacement is to observe the curing results. If the gel curing time is significantly prolonged (e.g., far exceeding the time specified in the product instructions), the nail surface becomes sticky and soft after curing, the coating cracks and peels easily, or customers frequently report an unusual burning sensation during curing (this may be due to reduced lamp efficiency, forcing extended exposure times), these are strong indicators of lamp aging. At this point, don't rely solely on whether the lamp is lit. Even if it is, the UV intensity may no longer be sufficient to effectively activate the gel. Regularly evaluating the actual performance of your UV gel nail drying lamp is crucial.

To ensure effective manicures and operational efficiency, it's recommended to keep records of UV gel nail drying lamp usage and perform regular (e.g., quarterly) curing tests with standard gel. Even if the lamp's theoretical lifespan has not yet been reached, it should be replaced if curing efficiency decreases. Furthermore, professional manicurists should wear professional sun-protective gloves during operation to effectively protect the skin from the long-term effects of residual UV rays. Maintaining the UV gel nail drying lamp's lamp in optimal condition is essential for ensuring long-lasting, beautiful manicures and a safe, smooth service.
