If they have LEDs as small as the bulb on the right with leads attached (in warm white) I'll bite.
I don't think anyone is going to find a teeny tiny, 1mm, 40mil diameter LED with an omnidirectional radiation pattern any time soon.
LED dies radiate sideways so somehow you need to turn the planar radiation pattern into and omnidirectional pattern.
Well, back in the day, taylors, allegedly, used to use several upturned round-bottommed flasks placed around a single candle or oil lamp to provide better illumination. Light radiation from a candle or oil lamp is more or less planar, So...
What if you encase an LED die in clear epoxy filled with lots of tiny glass spheres. Mount the die, wire bond it and then encapsulate, what could be more simple. Have any LED manufacturers made any effort to try this ? I serious doubt it.
Probably need the computing power of a GPU to model an almost planar(ish) light source surrounded by lots of randomly distributed ball lenses. Maybe a neon and a handfull of glass balls (marbles) would be quicker. Damn I lost all of my marbles but you can probably buy them on ebay.
Anyways, good luck with finding teeny tiny incandescent light bulbs.
