Ketra’s bright idea brings dynamic LED lighting to affluent smart homes

The transition from incandescent light bulbs to LEDs improved home lighting in a number of ways. For one, LEDs are more efficient, so even though the upfront cost is higher, the bulbs last much longer than incandescent and use far less energy. LED bulbs also light up to full intensity almost immediately, they don’t produce much heat, and unlike compact fluorescent lights (CFLs), they’re not sensitive to cold temperatures.

Sounds like a slam dunk in favor of LEDs, but that doesn’t mean there isn’t room for improvement. Far from it, a startup called Ketra is advancing LED technology through dynamic light, which is light that changes in intensity and color temperature based on the time of day or other factors, such as a special occasion or simply consumer preference.
