PLEASE NOTE: CHECK MEASUREMENTS BEFORE YOU BUY, with a ruler or tape measure to make sure it will be a good fit. 14.25" from bottom of lamp to bottom of bulb socket, harp is 7", base is 7" diameter, 23.5" tall from bottom of lamp to the very top of the lamp. This Tiffany style lamp base is a great replacement for your stained glass shade, cloth shade, or virtually any shade that will fit proportionally. It's a sturdy, cast metal lamp, not resin. The classic Bronze finish works well with a variety of decor. The E26 standard Medium bulb socket is rated at 60 actual watts. These type of bulbs are very commonly available at any hardware store, and even right here on Amazon. You can use a conventional incandescent bulb, or you may use a LED replacement bulb, which will allow a brighter bulb, up to 100 w "equivalent". That means the LED will be as bright as a 100W incandescent bulb, but uses much less power and will work fine with this base.
