We saw a couple of cool hand-held continuous lightsources at this year's PhotoPlus tradeshow. We liked the IceLight in particular because of how much it resembles a lightsaber. And while it won't cut through a Tantan with ease, it is dimmable, portable, and throws out some very clean LED light. On a full charge, with the power turned up all the way, the IceLight will last you a good hour of continuous shooting. Available this fall, it will retails for somewhere around $500.
