NAB’s show floor last April signaled new directions in LED lighting. I’ll get to them below, but first a few thoughts on the evolution of electric lighting itself.
We complain we live in a time of dizzying change, but the 1880s were equally disorienting. Edison had patented his carbonized filament and Eastman his flexible roll film within a few years of each other. Electric lights, practical photography, motion pictures had arrived all at once it seemed. Modern times at mach speed.
It’s happening again, as digital imaging eclipses photochemical and filaments white-hot from electrical resistance yield to cool, compact fluorescent lamps (CFLs) and LEDs five times as energy efficient. more
