How big are the energy savings worldwide if everyone uses LED instead of regular lamps?

There’s more to consider in the discussion of energy “savings” when switching to LED bulbs from incandescent. If energy is neither lost nor destroyed the extra energy used to operate an incandescent bulb for light is largely taken up by producing heat.
In a building, that extra energy given off as heat isn’t necessarily “wasted”. If you’re living somewhere that requires the home to be heated an argument could be made that the “wasted” energy would be the difference in cost or efficiency between the buildings normal heating source and the energy used by the incandescent bulb. There’s likely efficiency gains from the incandescent bulb in this scenario as you’re heating only the space that you’re currently occupying.
My point in large is that the energy savings by switching to LED lighting is exaggerated or at the least doesn’t take into consideration all determining factors. Then there’s the side discussion on cost and energy required to produce the LED lamp and the cost paid by the consumer. Also, IMO incandescent lamps generally produce a much more pleasant light as the CRI of mass produced consumer LEDs is garbage.
