Review on ⚡️ iSmartLED 4 Switchable LED Lighting Levels – Dimmable Daylight White, A19 Medium Base Bulb, 60W Equivalent, E26/E27, 820lm, 6000K by Cindy Payne

Very affordable compared to similar lamps. Also, there aren't many low wattage 4-way bulbs on the market. They are easy to turn on and off. I tried the bulb in a vertical Ikea floor lamp and in the ceiling. They all work without problems for a couple of weeks. The difference between the brightness levels seems to be more noticeable on the ceiling than with a vertical floor lamp. I like to use the brightest level when working at home. Level 2 provides the ideal brightness for watching TV or chatting with friends. When I leave the house at night I turn it on at level 3 and it only costs 2.3W to provide a similar brightness at level 2. Finally, I hardly used the 4th level as I like the darkness at night. But I think it should be good for night light.
