I was in San Francisco the other day and an Ace Hardware store had cfl bulbs in a number of colors, like red, orange, yellow, green, etc. I bought a green one. It looks so cool in my lamp! So, I guess I really went "green!"
I saw those in Wally World a few weeks back, thought how neat and kept hunting for outdoor bulbs which, apparently, they don't carry in clear. Those also came in green, blue, red, etc....just what I would need for temporary lighting in that corner of the very large yard.
FWIW, I have one cf bulb that has been in use for 10 years now and the 24/7 one in the bathroom is pushing 5 years now.
