Einstein E640 Flash Unit
Few monolights can live up to the hype they are given. The Einstein E640 Monolight is the exception taking into considering the size, performance and features. Featuring 9 f-stop power variability (2.5Ws to 640Ws), consistantly firing at 5600K (in Constant Color Mode) alone or while working with multiple lights and the easy to read LCD on the back of the strobe head are just a few things that separate this monolight from the popular AlienBee lineup. Recycling quickly at 1.7 seconds at full power drastically increases as power decreases allows you to catch those important moments where you need to stop action. Using the Action Mode the flash duration is minimized for maxiumum stop action. Pair the E640 with the Cyber Commander and you can easily control multiple Einstein units.
