Streamlight is an ISO 9001:2000 registered company located in Eagleville, Pennsylvania that manufactures flashlights powered by various rechargeable and disposable batteries. Streamlight flashlights are often used by public safety professionals such as police officers and fire fighters, and they are often seen on television shows such as CSI: Crime Scene Investigation. Specific models are designed to be intrinsically safe for use in hazardous areas.
Their product line features hand-held and weapon-mountable lights as well as a small handcuff-key light. Several of their products utilize dual sources, combining the long life of LED lamps with more powerful but shorter-lived conventional incandescent lamps. They also produce a series of Laser Illuminators such as the M6 shown in the image at right and the TLR-2 which is a combination LED weapon light and laser.
Streamlight developed the first million candela hand light for NASA in the early 1970s.
