I ordered two lights, and installed them a few days after they were arrived. First, the tiffany lights are not glass -- they are some form of plastic (lucite probably). The look nice, and they are lighter than expected. Then sconce weighed 6 3/4 ounces, plus the base. The installation kit was more difficult to install than any other sconce I've done before. Based on the weight of the light, a simpler installation kit could have been used, and it took about 45 minutes to get the first one in place. The backplate was a bit hefty. The website says to use two max 40 watt bulbs, but the backplate identifies max at 60 watts. I went with 40 watt incandescent bulbs, mainly because I was concerned about heat from the bulbs melting the plastic panels. Both lights were identical in color and shade. All in all they looked good when installed, and the give off plenty of light. Worth the money.
