These LED lamps are wonderful, they are the ideal lamp for replacing old 60W incandescent bulbs, they have with only 4.5W greater light output than the wasteful 60W bulb. I have to run White because I insets substitute for my outdoor lanterns, basement, utility room and hallway. White is not for everyone but I think especially for areas where there is movement or working is this crisp light very helpful. For a cozy comfort zone of course very cold and getting used to. This special E27 high 96x5730 SMD LEDs bring loose the advertised 600 lumens, how long this luminosity unfortunately I can not but say a loss of 10-20% over time would mean only an approximation to the old 60W. Eco-friendly, highly efficient, no mercury, no UV and infrared radiation. I have a really good feeling with these lamps and order me once more because I only had 4 pieces ordered for testing. Saving energy I have written as a family man with a 6-person household as a personal need on the flag and over the past 4 years my former annual consumption of 11.000kW / h on 6.000kW / h almost halved.
