The Turbo USB and the Turbo CR are designed with the latest XML2 LED technology and produce a stun- ningly brilliant 700 lumens of ultra white light as measured against the ANSI FL-1 Standard. Both lights in the Turbo Family also have several key features, including a 3- position, quiet switch (intermittent, locking and constant-on) and a foamed, vinyl grip that is durable yet tacky and provides insulation from the heat these types of lights give off.
