I needn't say much here, because reviews of this recent light are easy to find. I mention it only because, as I had hoped, it's bright enough to serve even with some large format work, such as portraits. Although I am trying to use natural light primarily, interiors can mean uncomfortably long shutter speeds. This LED is bright enough, for my work, to squeeze by as an "emergency" bounced key light, and is more than adequate for bounced fill. Power is dialed up and down simply. I shoot HP5 in 4x5, generally at between 200 and 800, depending on conditions. The low power consumption (120 Watts) means I can plug in anywhere without worry and carry a lighter extension cord than for my 500- to 750-W halogen lights. It's not as compact as the Lowels, of course, but it's not huge or heavy, either.

I haven't ordered a battery yet (I have to sell some equipment first), but that's another neat feature.
