They build higher capacity bulbs by adding more LEDs.
If they ever get around to making specific shapes, with surface emitters, they will be able to make them omnidirectional and very efficient.
I wouldn’t be surprised to see something like an old-fashioned candlestick, with an LED source, and a rechargeable battery. Heck, keep it in the living room window and let the sun recharge it.
Multiple emitters had got them to the place where they’re replacing traffic lights with multi-HILED units that I’d expect have their own integrated step-down transformer and DC rectifier.
Given that, there’s definitely hope we’ll soon see something other than a flashlight for residential use.
