I have replaced all the saving bulbs in my house with these led bulbs. The bulbs in my house were 22w energy-saving bulbs. I was very pleased with the Philips 9w, it gives 2 times more light than the other bulb and consumes 3/1 less energy. 12 pieces including shipping costs 37 €. http://lgub.2track.info/?redir=https://www.aliexpress.com/item/4000461203833.html
