Never be caught with a flash tube down. Keep one of our glass shielded flashtube spares handy. All you need is one unexpected fall, stray meteorite or a clumsy assistant, to ruin the shoot. While XPLOR 600Pro TTL600ws flashtubes are designed to deliver much greater than 100,000 pops, conditions of use, power cycling and exposure to vibration contribute to the real lifespan of a monolight flash tube. A typical flashtube in top shape can be in service for over 250,000 flashes. The Flashpoint XPLOR 600ws Flashtube simply plugs in to the 4 pin socket and you are back in a flash.
