Helped someone in a new home that had a bulb in the ceiling fan. The light is on a dimmer. It was a 60W lamp. It has a slight tint so I needed an A19 bulb. I also wanted a warm light LED. Also, it should have been brighter at high frequencies since it's the light in the room at that moment. It worked well. As others have said, the light color is good. Checked hardware stores and A19 equivalent 100W LED dimmable was out of stock. No big deals for 100 miles. No data or information on effectiveness.
