Alien Bees Einstein E640 Flash Unit

Rent an Einstein E640 Flash at TheLensDepot.com

Einstein™ is a powerful, all-digital, self-contained flash unit using multiple IGBT devices to allow a 9 f-stop power variability range from full (640 Ws) to 1/256 power (2.5 Ws), adjustable in precise 1/10 f-stops with voltage regulation consistency over the entire operating range.

Einstein™ offers global plug-and-play with automatic power switching that allows the unit to operate on power lines from 95VAC to 265VAC, 50 or 60Hz, automatically sensing the voltage / frequency and adjusting accordingly with no user attention required. The unit can tolerate power line voltages as low as 35VAC from the Vagabond™ II portable power system or from other similar pure sine inverters without crashing, whereas many competitive digital flash units crash if the input voltage falls below about 80 to 90VAC. No user intervention or lamp changing is required to operate at different AC line voltages.

Einstein™ recycles to full power (at 120VAC or at 240VAC, 50Hz) in just 1.7 seconds, with the recycle time proportionally decreasing as the power setting is reduced. When recycle is complete, the READY state can be indicated both audibly and visually, selectable from the rear panel. An advantage of the IGBT flash control is that, at reduced power settings, the flash capacitors are not completely drained when the unit is fired making it possible to perform a rapid sequence of shots as the unit can be fired before the READY state is reached. Depending on the power setting and number of frames per second being shot, this can produce successive reductions of exposure value and color temperature in a rapid series of shots at relatively high power. In typical fast action sports shooting, setting the power to around 1/10 power (64 Ws) will allow frame rates or bursts on the order of five to ten frames per second with excellent frame to frame consistency and extremely sharp action freezing.

Rental Includes: One E640 Flash Unit, Sync Cord, Power Cord and Reflector
