I still use old style non energy efficient bulbs like these for two reasons: 1) I like to be able to actually receive light when I switch on a light - not a slow sunrise and 2) £4.09 for one of these bulbs in Ikea of the energy efficient variety. Not on my watch.
Bulbs are bulbs at the end of the day, they arrived promptly, safely packaged and none were broken. One bulb only lasted two weeks however the other are still fine. Oveall no complaints and quick delivery.
The bulbs work fine until they point vertically down and i have had 3 of 12 shatter.I accept it may not be the bulbs but the fitting in which they are set. Just to let fellow Amazonians know of my experience.
