I have these 4 LEDs used in my hallway in a lamp that has narrow glass tubes with E14 socket for lamps. The light is a Tick colder than warm light, but just in the hall, I find it very good. They are very bright and the specification of 480 lumens does not seem exaggerated. For more than 8 months now they have been in operation without failure. Since the SMD (LED) have no protective cover, are are really only suitable for versions with glass or cover. Overall very good value for money and a buy recommendation from me!
