Like Joe Geek Offer, I went thru the CF stage and have now begun to do almost all LEDs. My wife still likes a few old incandescents for her craft work, but we have enough stored up.
   In the USA, there are more & more deals and styles of LEDs daily and I am careful with dimmers. It seems to me that LED technology is the wave of the future and, although it is not always convenient for older homes to adapt wiring & dimmers, our children & grandchildren will wonder at how Edison's invention lasted so long.

(I have 6-7 WWII blackout bulbs with only a small area at the tip to allow light through. There are people who 'collect' ancient light bulbs.)
