UV-LIGHT for checking watch lume is typically used to enhance the visibility of luminescent materials on a watch dial and hands. When exposed to UV light, these materials—often made from substances like Super-LumiNova—emit a bright glow, allowing you to assess their brightness and uniformity. This method helps determine if the lume is still effective or if it has degraded over time. UV light can reveal any inconsistencies or fading that might not be visible in regular lighting conditions.

WHITE LED torch emits visible light, typically in the range of 400 to 700 nm. It provides bright, focused illumination and is commonly used for general lighting purposes. In the context of watch lume checking, a white LED torch can help assess the overall visibility of the watch face but may not effectively highlight luminescent properties like UV light. It can be useful for examining the watch in various lighting conditions but won’t reveal fluorescence or glow characteristics. It has maximum from 100-200 meters.
