The lamps produce a beautiful warm light, very similar to a light bulb. They heat up and emit hardly in all directions. The luminosity ok, but usable only in larger numbers - making 4 pieces in as much light as a 70W light bulb, I would appreciate - the specified power of 5 watts is more embellished. What's really bothering but that the lamps during insertion into the socket have no solid electrical contact. I've tried with 2 different light sockets - when a little contact, in the other not. After a few trials it has been found that the contact flags of the lamps are too wide. Filed 2 tenths mm and the lamps fit into the socket. Due to the beautiful light and very reasonable price recommended anyway.
Edit after 2 weeks: The light is significantly more yellow than in a light bulb. At first I found the light very beautiful, but now I'd rather have a less yellowish optical sound.
