They're working just as hard for IR (in the form of laser diodes),
and making great strides there as well.

White LEDs have become one of the most efficient light
sources.
Is that really true? I would have suspected that red LEDs would be
far more efficient in terms of lumens-per-watt. The drawback being
that they're monochromatic.
