Hydro-Force now offers two UV flashlight models. The low-end model is rated to 100,000 hours of bulb life. It can be used in daylight, but works best when lights are dimmed. The high-end model, manufactured by Maglite, features special circuitry that doesn’t allow the bulb to dim as batteries age.

The company also offers amber glasses to keep the operator’s eyes safe and allow better viewing of stains.
