B1 500 Air Battery-Powered 2-Light Location Kit from Profoto consists of two B1 500 off-camera, battery-powered AirTTL flash heads, a 4.5A Fast Battery Charger, car charger and a custom location backpack. Add an optional Air Remote TTL-C, TTL-N, Air Remote or Air Sync for wireless triggering from distances up to 1,000'.
This versatile kit makes studio quality lighting as easy to use as your camera's TTL flash. The B1 offers double wireless freedom - a built in AirTTL receiver for remote triggering as well as a powerful on-board Lithium-ion battery that untethers you from the wall outlet. When you need to recharge, the included Fast Battery Charger lives up to its name by providing up to 220 500W/s flashes on a 60 minute charge while the car charger allows you to refresh the battery while you drive to your next shoot. The kit fits in an included ballistic nylon backpack which was tailored for it. Its interior features padded compartments and room for expendables and optional Profoto transmitters. Currently the B1 offers full TTL exposure plus remote triggering for Canon cameras via the optional Air Remote TTL-C and for Nikon cameras via the TTL-N. The B1 can also be triggered remotely with the Air Remote or Air Sync without TTL functionality.
The B1 recycles in 0.1 to 1.9 seconds but can deliver up to 20 flashes per second in Quick Burst Mode which engages at lower power settings. Flash duration in Normal Mode is a very fast 1/1,000 sec. but there's also a Freeze Mode that delivers flash durations a short as 1/19,000 sec. for capturing liquid sprays or splashes and other creative effects. The modeling light has been upgraded to LED to put less strain on the battery and provide the equivalent output of a 70W tungsten-halogen bulb. The B1's exchangeable Lithium-ion battery gets up to 220 flashes on a 2-hour charge with the standard 2.8A charger or a 1-hour charge with the 4.5A Fast Charger. The battery has fuel gauge-type LEDs that make monitoring remaining power easy.
