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.
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.
In Action Mode, the color temperature rises as power is reduced, but the t.1 flash duration is minimized even further for maximum action stopping capability where absolute color consistency is secondary to motion freezing.
IN ACTION MODE
In this mode, the emitted color temperature is held constant at 5600ºK, plus or minus 50ºK at any power setting or input voltage. At full power, the t.5 flash duration is 1/1600 second and the t.1 time is 1/568 second.
CONSTANT COLOR MODE
THE RANGE OF POWER
The range of power reduction is typically limited to 1/8 to 1/32 power, often resulting in aninability to achieve low aperture settings with close lighting techniques
The median t.1 flash duration of the ten most popular promonolights ranges from 1/200 second to 1/400 second – too slow for sharp freezing of action in sports, dance and other rapid movement shots
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.
