These bulbs are great, bright 3 way bulbs. They are 18 Watt, A21 LED, Non-Dimmable light bulbs, Tunable White E26 Medium Standard Base.  These put out a lot of light which is what I needed as my lamp shade is decorated and a regular bulb did not put out enough light, but these sure do.  I am very happy with these.  Pictures are of the 3 way light changes.
