Extremely portable and featuring a 2.4 GHz power control wireless receiver, the Baja B4 Battery-Powered Monolight from Dynalite is a 400 Ws strobe that can be taken on-location without the need for any cables. The Baja B4 uses a rechargeable Li-ion battery which can provide up to 550 full-power flashes on a single charge. Also, users can adjust the power in 1/10-stop increments through a 6-stop power range and it has a recycle time of about 2.9 seconds to full power.
The Baja B4 features a flash duration ranging from 1/12800 to 1/500 second and an LED modeling light. High Speed Sync is available for most Canon DSLR's when used with the optional DYBRT616C transmitter for Canon cameras. Nikon users need to purchase a dedicated BYBRT616N Transmitter and also a DYBRR616N dedicated receiver.
A built-in optical slave contributes to the wireless convenience by triggering upon the firing of other strobes. A stroboscopic C-mode is also available for 5, 10, or 15 flashes per second. Additionally, it has audible flash indicators, a glass dome, metal light stand swivel mount, and a standard Bowens accessory mount. Included with the light are a receiver, umbrella reflector, clear protective cover, and a clear protective cap.
