LED efficiencies have dramatically improved recently. 100-200 lumens/watt is common and improvements are still coming (reference, a typical 100 watt tungsten bulb produces about 1600 lumens (~16 lumens/watt)).<p>This project uses 32 LEDs, each of which can produce ~250 lumens, emitting 8000 lumens in total, and it only draws 88 watts! (current lighting solutions used in the field yield 8000 lumens and take 1000 watts! - an order of magnitude less power).<p>On top of that, the lights can be more-afordable and this project can be arduino-controlled, wi-fi enabled, and it's _open-sourced_(!). Pretty awesome!<p>Work like this could significantly lower costs/barriers to high-quality film-making and photography in various cases.<p>Production films, for instance, typically hire union electricians to deal with the electrical demands of lighting. The logistics of making sure you have circuits to handle the load and safety can be a pain. Carrying around heavy lighting is a pain, etc. Also purchasing these large lights is expensive.<p>It will be interesting to see how quickly/widely adoption takes place.. and I wonder about other effects it will have in other areas..
