We've switched gradually as the old style bulbs burnt out. Our monthly equal pay electric bill was 173.00 a month 2 years ago. It has dropped by 40.00, and the only thing different is the bulbs.
It did take some getting used to in lighting that shows the bulbs. Didn't take long to forget they were even different.
and I'm careful which type of light I get, the bright white I hate, too cold feeling. Might be my age.
