Switch between UV light and white light to catch defects you'd otherwise miss with these handheld magnifiers. Their UV LEDs illuminate fluorescent dyes and particles, making leaks, cracks, and tears easy to spot. The white light LEDs mimic natural daylight for a crisp, clear view of fine details. For even lighting with no shadows, both types of light are arranged in a ring. Adjust the brightness with the dimmer to reduce glare on reflective surfaces. These magnifiers have an ESD (electrostatic discharge) safe coating that dissipates static electricity, so they won’t pass along harmful charges if they touch sensitive components.
