Overall, really like the lamps. They look great and add the ambiance I was going for. These definitely aren't reading lights, but add a nice "glow" to the room. The base isn't as "hefty" as you might initially imagine from the pictures (the base is actually hollow) but is sufficient for it's purpose. Total weight of the lamp is ~336grams. One thing to note, these require an e12 base light bulb (not a standard e26). You might also find these sold as "candelabra" or "chandelier" bulbs. Though the description here currently states 60 watt, the manufacturer recommends a "7 watt max" bulb (which would leave you looking at LED or CFL).
These lamps are awesome. I intially order the square lamps in orange, and was so impressed with how quickly they came (48 hours) and how well they fit into the space, that I went forth and ordered these round ones in green. These showed up just as quickly and work great. Keep in mind that the manufacturer reccomends usuing LED bulbs which make the lamps better suited as ambient lighting vs. a primary source. Regardless, these are a great find and excellent value!
Would have given 5 star review - BUT the inside of each of these lamps had torn/ripped areas (not super big) from what I don't know! Would have returned them but you cant see torn areas when lights are on. Otherwise these are very neat lamps - we used LED bulbs in them as they do not get hot.
