The LD05 V2.0 is a super compact penlight that is must-have for medical workers, police officers or every day carry (EDC). This is one of the best penlights out there, featuring three brightness levels of very warm 3000K white light from the 90 CRI Cree XQ-E HI warm white LED, plus a 365nm UV light; both of which are operated by the stainless steel tail switch. Powered by two included AAA batteries, this light delivers a maximum output of 100 lumens (which qualifies it for medical or certificates inspection). The UV light is great for counterfeit currency detection. Waterproof, dustproof and extremely durable the LD05 V2.0 will be your favorite penlight.
