As you know the Federal Government is fazing out the old incendesent light bulbs, so the question I have for you is in your house or apartment, how many of them do you have left. Here is my count on that:
2 Porches back and front
1 Washroom
1 Kitchen
2 Den
7 Living Room
3 Bathroom
1 Hall
3 Back Bedroom
3 Front Bedroom
That is the down stairs
This is the upstairs
2 South Bedroom
3 Middle Room
2 Two storage areas
My room has none, which totals for the whole house 30

Not sure. We have only a few environmentally friendly bulbs. But their brightness sucks.
