---
The AlienBees™ B400 is a powerful, self-contained studio flash unit with adjustable output from full power (160 Ws) down to 1/32nd of the total power (5 Ws). This flashpower is adjusted on the back control panel with a slide fader, capable of adjusting in whole f-stop increments and everywhere in between. When adjusted from a higher to a lower setting, the unit will automatically dump the excess power for accurate output.
With precision voltage regulated circuits supplying consistent output, the B400 boasts true “what-you-see-is-what-you-get” modeling lamp accuracy. The modeling lamp can be set to full brightness, turned completely off, or set to track the power changes. Furthermore, the standard 150 Watt modeling lamp may be used as a recycle indicator, turning itself off when the unit is recycling, and coming back on to let you know when the unit is fully recycled and you are ready to shoot again. Ready for heavy-duty, all-day shooting, the AlienBees™ have built-in cooling fans to keep up with their fast recycle.
The B400 arrives with a sync cord allowing you to connect your camera to the unit to trigger the flash. The unit additionally has a built-in slave tripper to allow wireless firing. The unit has standard 120 VAC (50-60 Hz) power requirements and arrives with our 15-foot power cord to connect to a standard, grounded outlet for power.
Both versatile and indestructible, the AlienBees™ units are housed in high-impact Lexan polycarbonate (the same material used for bullet-proof glass), keeping them lightweight and ready to travel.
