Probably going to sound crazy, but we could start running water pipes in front of the walls and under the ceilings and mounting the LED's directly on the pipes for cooling. Creativity, thinking wholistically... the entire contemporary western house design needs a rethink frankly, from DC circuits to electrification to modular, mass-produceable utility drop-in pods, all with an eye towards integrated systems design paired with scalable modularity.

In a normal house you're not going to need that much light that you'll need water cooling.

Simple metal fins are more than sufficient along with a high efficiency power supply.
