Induction lamps are getting big - but most people want to get rid of the mercury vapor arc entirely and go for solid state, that's a big enough advantage that energy efficiency almost doesn't matter.
Unfortunately, Switch didn't figure out that the light is no longer "solid state" when they added liquid to it - and that a non-toxic liquid is probably worse in many situations than a toxic vapor.
