Nice lights! One of my bitter disappointments growing up: we had a roof equipped with lots of hooks, probably used for a previous occupant's lights. But we never had lights--my father, I think, said "no" because of the electricity used.

I've used C7 lights in recent years inside. I don't feel guilty--I figure the waste heat just helps heat the place. My heating is electric, so I figure it's the same, except at least the lights are pretty!

That is exactly correct. There is no waste with Christmas lights inside during the heating season. .... or any lights running, for that matter.

4 sets of 25 C7 ,or C9, bulbs,
at 7 watts each bulb
is using 700 watts per hour.

compare: the lowest setting on an electric heater uses about 500 watts.

IF you have them on for roughly 6 hours a day = 4200 watts a day
x 30 days a month = 126000 watts a month
= 126 KWH in a month
x $0.10 average KWH billable from utility company
=$12.60 a month to operate

If they were LED it would probably cost about $0.50 a month to operate, but I don't think they give off much heat, and the looks.....?

I know it's not eco-smart, but I like my incandescent bulbs.

My brother and I used to hollow out a hole in 4 or 5 inch white Styrofoam balls to accept a C9 twinkle light and put them on the holly trees at either end of the house. We alternated the twinkle balls with steady burning lights to give some balance to the trees. You can't do it with the steady burning bulbs because the heat melts the Styrofoam, but twinkle lights work just fine and the color comes through the foam to give a big lighted ball.
