The B1X 500 AirTTL 2-Light location kit from Profoto includes two fully battery-powered B1X strobe heads, batteries, and charger. All of the familiar professional and convenience features we've come to expect from Profoto are onboard. The fixtures have an integrated 77-degree reflector, built-in receiver compatible with Air Remote TTL remotes, and intuitive highly visible controls and display.
The B1X 500 AirTTL employs an improved, high-capacity, exchangeable lithium-ion battery that gets up to 325 full-powered flashes on a 1.5-hour charge with the included 4.5A quick charger. The battery has fuel gauge-type LEDs that make monitoring remaining power easy. The B1X's modeling light is LED to put less strain on the battery. It provides the equivalent output of a 130W halogen bulb and will run for 120 minutes on a full charge.
The fixtures are also capable of High-Speed Sync. HSS is the technical term for syncing flash with shutter speeds shorter than the so-called x-sync, typically 1/250 of a second. It's a useful tool for controlling ambient light and for freezing action. Profoto uses a patent-pending technology that emits an extremely fast series of flash pulses. A simple button-press activates HSS Mode allowing you to shoot at shutter speeds as fast as 1/8000 of a second.
Finally, B1X's back panel features a large, bright LCD screen that informs the user of the flash's power level, radio channel and group, sync choice, modeling light mode, and recycle alert. There's also a large battery gauge that literally can be read from 20' away.
