Originally designed with the demands of Battlefield Forensics in mind, the BattleLites are the perfect tool for site exploitation and evidence collection. Three specific wavelengths 455nm (blue), 505nm (green) and a pure white light are included with this kit. Each rugged 3-watt forensic light has many features, including a blinding single LED capacity, a hi-lo power switch (for battery conservation) and thumb (on-off) switch. Shock, dust and moisture resistant. All light heads are interchangeable (and other colors (wavelengths) are available on special request.)
