Einstein E640 Studio Flash Unit
Available Today
The Einstein E640 is Paul C. Buff’s top-of-the-line monolight strobe. The unit features all-digital controlling from a 2.4" high resolution LCD display. Gone are the days of the slider-bar. Controls are now adjustable in precise 1/10 f-stops through dedicated function and adjust buttons. The Einstein offers a very welcomed 9 f-stop power variability that allows light adjustment from 640 w/s all the way down to 2.5 w/s. It has a quick recycle time of 1.7 seconds at full power, and dramatically increases recycle as power decreases.
There are two operation modes that allow you to control what’s most important based on what you’re shooting. In Action Mode, the flash duration is minimized for maximum action stopping capability where absolute color consistency is secondary to motion freezing. In Constant Color Mode the emitted color temperature is held constant at 5600ºK (+/- 50ºK at any power setting or input voltage) and the flash duration fluctuates.
The frosted dome cover reduces UV emissions while protecting the bright, voltage-controlled 150 Watt modeling lamp and UV-coated, single ring flash tube. The strobe features both audible and visual recycle indicator alert options for shooting away from the unit. The built-in fan allows for cooling the unit during heavy use. It has a standard 1/8" sync-port and is fully compatible with all our AlienBee modifier accessories.
