I have changed over an led tv here too. Kinda had too as I got tried of buying convertor boxes that only lasted two years. I probably had a lot more of wattage difference as it was an old analog tv. Both of the computer monitors have been led for quite awhile too. One nice about the new tv is that I can now connect to the net and play free movies even I seldom watch them.
Just repair the hot water heater and it going to be using less wattage too as some idiot installed 4500 watt element after the last one failed. I was wondering it always sounded like something frying when heating water. It now has the right 3500 watt element it is now quite when heating.
The next major project is a central unit as the compressor had failed 2 yrs ago. I probably install a hi efficient heat pump version. I currently using resistance heating elements, so the meter gets burn out marks everytime the heater comes on. It probably why I am sitting in a house that is only 15c but that better than the -2C outside currently.
The led bulbs are currently around 6-8 usd a piece. As far incandescent bulbs they are getting hard to find but CFLs and LEDs are all over the place. At lease the prices are coming down now.
