I wonder what the economic calculation looks like. How much efficiency would be lost by doubling the lifespan? It depends on the relative price of lightbulbs and electricity, and the cost (in time/effort/inconvenience) when a bulb blows.

Saudi Arabia has regulation on the lightbulbs which require more LEDs run at lower power.

They last a lot longer.

		Yes LEDs massively change the parameters, I'm more talking about the historic Phoebus cartel and the properties of incandescent filament lamps.
