Review on EcoSmart Daylight Energy Dimmable Industrial Electrical Lighting Components by Nicolai Goler

These bulbs (3 pieces) have been sitting together in a lamp in my dining room since I bought them (March 2018). I have them on my dimmer. I use this light at best 12 hours a day (that's more than actual usage). One of the three lightbulbs stopped working in July 2020. The one remaining of the three bulbs, which is still in the socket and still working, gave out a high-pitched hum, which is quite annoying (especially if you have good hearing like me).
