Agreed.
The increasingly pertinent measure is lumens - since watts no longer relate logically to brightness, the 100w equivalent is something like 1500 lumens?
I think currently it’s something like 100 watts = 1500 lumens = 26 watt CFL?
I’m sure there’s some LED equivalent way down around 5-10 watts, but they’re still astoundingly expensive.
LED lighting is costly because of the electronic boards and circuitry required to make them work. The trade off is in the savings in electricity as well as the decades of trouble free operation they will yield. As far as being economical, there is no fair comparison. The LED wins hands down.
