Question: how thick is the base? (it has to slide under my couch)
Document: I purchased this item largely due to the photograph which shows a base that appeared as though it would mostly fit under my couch...the lamp I received had a different style base entirely and does not fit under the couch.
What I received has an enormous base about three inches thick in back and a U shaped aluminum tube base (no gap). It definitely won't tip over, but at the same time it really could make positioning it difficult and might force me to space the sectional out 4 inches or so from the wall.. I have yet to get my sectional, but I could definitely imagine this might create some problems for people with sectionals low to the ground.The unit comes with five 40 watt candelabra base incandescent bulbs.
Easy to assemble, looks great! Comes with lightbulbs, which I did not expect. I am pleased with the product.The only negative that I have found is that the floating lights move with movement on the couch, where the stand sits under it. I would have wished that it was a little sturdier.
The Lamp is exactly what I thought I was ordering. Price was competitive. It was easy to assemble. Despite the shipping box looking like it had been threw a war, The contents where all is great condition without a scratch. UPS needs to do better with the way they handle packages. Looks great behind our wraparound couch in the corner.
I bought this to light behind my sectional couch. The build quality is a bit questionable. You have to screw the five lamp covers to their respective branches before putting in the bulb. One of mine had the threading cut too short on the branch, making it impossible to get the cap to screw on its own. I ended up having to superglue the cover on, which seems to be holding reasonably well, but as a matter of principle I shouldn't have to superglue my things together!!
Also there is some sort of white stuff on the base that should not be there.
The lamp seems like it will be great but the piece connecting the base to the pole is too short and I have to find get another piece to actually put it together.
Has lots of brightness. It is TALL. Bareley fit under my 8ft ceilings. The on/off switch seems somewhat cheap, but I haven't had issues with it yet. The base is a lot bigger than I anticpated, but that was due to my not paying attention to the specs.
By nearly an inch. What this means, is that the screw would not attach to the body pole, and then come down through the base out the other end so that the washer could be attached so the base would be fastened to the pole. This lead me to either have to wait for X amount of weeks/months for the company to ship me the replacement part, or go to my local hardware store.
The lamp is very easy to put together. The base is quite heavy, but it has to be, or it would tip too easily. The arms are easily moved to space them evenly. The bulbs that come with it aren't the best, one was already broken when it arrived, but you can buy them quite cheaply at any home improvement store. All in all, I'm very happy with the lamp, and love the dimmer switch.
