If you want a three-way lamp, this is NOT it. The description is wrong. After receiving the lamp, I contacted Adesso and they said, "Please use a 100 watt maximum incandescent bulb. The lamp has an ON/OFF switch not an 3 way. There was a change.
It does not use a dimmer bulb." So, take this in consideration when purchasing. Three-way lamps are typically more money. So, I think the lamp is overpriced.
