[FRIAM] Naïve physics question

[Barry MacKichan]

An old North Carolina farmer (later confirmed by an advanced amateur 
astronomer) to put two incandescent bulbs in series. The halving of the 
voltage lowers the temp of the bulbs significantly, and at the lower 
voltage, the bulbs last essentially forever. I have no idea what happens 
if you do the same with CF bulbs.
