The Einstein monobloc strobe is listed at 640 watt seconds (ws) of power, has a bright 250-watt modeling light that can vary proportionally with the flash output, a 12 flash per second (fps) claimed capability, and a constant 5600°K color temperature, no matter what the power level. Also, a claimed nine f/stop range, from 2.5 to 640 ws, and Paul C. Buff's proprietary IGBT technology fill out the bill. It's solidly built, using a Lexan housing instead of metal. It's not very big, but is bigger and about a pound heavier than the company's AlienBees units that many photographers, including myself, use. After unpacking and placing on a light stand, the first thing you're going to notice is that colorful display on the back. No, it's not a video game. It's a sophisticated control panel that immediately makes you feel all your older lights are outdated.

机译：爱因斯坦整体闪光灯的功率为640瓦秒（ws），具有250瓦的明亮造型灯，可以随闪光灯输出成比例地变化，声称每秒12拍（fps）的能力，以及恒定的5600°K色温，无论功率水平如何。此外，声称的9 f / stop范围从2.5到640 ws，Paul C. Buff的专有IGBT技术填补了这一空白。它是坚固的，使用Lexan外壳代替金属。它不是很大，但是比包括我在内的许多摄影师使用的公司AlienBees装置更大，重约一磅。打开包装并将其放在轻便的架子上之后，您首先要注意的是背面的彩色显示屏。不，这不是电子游戏。这是一个复杂的控制面板，可立即让您感到所有旧灯都已过时。
