Light Relief

Sun et al (Princeton) report in Nature that they have efficient, long lived, bright white light organic LEDs.

Some engineering still to be done on packaging, the blue phosphor could be longer lived, but they appear to have good spectral energy distributions, high application flexibility and very high efficiencies. Like cut 10+% of grid electricity consumption efficient. Every bit helps.

Manufacturing costs need to come down, which should come with scale of production; expect early adoption "gizmo" users will be having some within a year or two.
