Worth it to me to save $30/month in electricity and have to change the light bulbs far less frequently irregardless.
In an earlier post I suggested that if I switched entirely to Gorebulbs I’d need to pay more for heating, since the incandescents throw lots of heat. But, many people posting to the thread have found a net reduction in energy cost across a year, suggesting perhaps, just maybe, the inefficiency of the Edison bulb is not as bad as has been stated by members of Congress. Of course I don’t know everyone’s local climate.
In a cold season or cold climate the incandescent lamp’s inefficiency should not matter since in any system inefficiency shows up as heat, which you pay for to warm your room.
It’s about 56 here outside, but it’s 68 where I am now, in part because of the incandescent desk lamp.
