Indicator lights alert you if the battery is low, or normal strength
The series of lightweight, handheld lamps offer UV wavelengths of 365 and 254 nm, or a combination of the two. They’re cordless and use 12 VDC rechargeable batteries. They can sustain three hours of continuous use or about 500 intermittent uses when fully charged. The models equipped with an automatic safety switch prevent harmful exposure to UV radiation if the lamp is turned upside down.
