The Huge waste that LED's , in general, present.
At their smaller wattage usage they should be quite a bit cooler than a incandescent bulb. NOT!.
All LED are a DC voltage diode. So each bulb has a 10:1 step down transformer, a 4 way bridge rectifier, and a condensor/ capacitor to get to a steady roughly 5 volts. This reduction causes HEAT!
If you have solar, you convert solar DC to AC, and back to DC to run LED's.
The tiny ac/dc converter in the bulbs is almost always a quality issue and cause for failure.
If houses has very low current 5 volt DC wiring ABOVE 4 feet in each room bulbs would NOT be hot, and never burn out.
There are LED'S in space that live at -400 degrees oF. They run on DC.
Some LED you could put in an easy bake oven!. The whole premise was to save energy, there is MUCH more to be saved.
