I agree. LED is the cost effective way to go. They come in a variety of styles and save a ton of money on the electric bill. I have gone all LED with the exception of my Gemmy inflatables. Plus I can connect many more sets of LEDs compared to the old school light sets. :)
I had to switch to LEDs just to save money not installing another electrical panel in the house.
we are about 1/2 & 1/2 now.. but buying more and more led sets as the old ones burn out.. also to save from upgrading the electric panel
when I went animated I saw my electrical bill drop by over 60%. As I phase out some elements and replace them with LED I see the cost saving increase.
