These bulbs seem to glow as their prices by their brightness! The packaging is quite correct, the design is well thought except for black scriptures that are a little too visible for my taste. They seem to produce almost as much light as the old bulbs of 40 W while consuming 10x less power! If you want to replace your old halogen bulbs or filament whose life does not exceed 2000 hours, jump at the chance and go with saving bulbs, you will be quiet for many years, and leaves your door too :)
