Question: can I use an LED bulb in this?
Document: I love this light fixture. It is beautiful and looks great in my walk-in closet. However, there is a bulb-shaped cage where the light goes, which restricts the size of light bulb that you can use. Even though it has an E12 bulb/candelabra base, you won't be able to use just any bulb with that type of base. The bulb needs to be very short and fairly thin.
It's beautiful can't beat it for the price! I was sceptical in ordering because of the reviews on the bulb, but i took a chance anyway. There is a bulb shape cage where the bulb goes and it request that you use a E12 bulb base 40 watt bulb. But where do you find one...Not at Walmart, Lowes, Home Depot. By the third try I got a bulb. you MUST get the 40 watt bulb that states  "CANDELABRA" on it,  a small round bulb.
So, YES, you can get a screwed in chandelier based light bulbanywhere!!! !For those that complained, it is because they are NOT use to a chandelier bulbs or were looking at the base in confusion.As for those, that too complained over material/structure of light, not sure what they where expecting, but you can not make a light out of iron/heavy material without weight and cost.
This came without any installation instructions and I have yet to find a bulb for it. Don't buy this light!!!!!!! !
Just put up 3 pendant lights and I love it. The manufacturer must have changed the required bulb because I used just regular 60 watt cfl bulbs. cord should be a little longer, and it took me forever to out on each crystal, but my electrician had a very easy time with installation
I love the light fixture and it looks great in my master bath. The only problem is that it was made with what appears to be an upside down lamp shade to which the dangling crystal ball is suspended. The space for a light bulb is very small. It took three attempts to find a bulb that was either short enough or small enough from a diameter standpoint that would fit. It should come with a bulb since the space is so limited.
(I previously checked Lowe's, Home Depot, Walmart and Target. )LightInTheBox sells their own bulbs to fit, but they are 6 watts and too dim to light even a closet. (A chat agent pointed me to that bulb specifically for this light. It took 20 days to ship from China and was a disappointment.) If you want this light, I would suggest making sure you can get the correct bulb first and save yourself some hassle.
This light matches perfectly with a ceiling mount light I purchased on overstock. The picture of the canopy is not an accurate representation as there are round screw covers on the canopy and the picture only shows a center opening for the cord. These are replacing 100w lamps in our Master bath so I have been on the search for the highest lumens for a 40 watt candelabra bulb. I used the cord covers from my original lamps as the cord on these detract from the overall look.
I explained about the E12 bulb base 40 wattt but was uable to find. So he explained to me about the CANDLABRA bulb and that it fits all chandelier type lamps. He also told me because the base is to small that to turn the bulb counterclock wise then turn it clockwise and it should screw in,  at first I heard a cracklin noise (i though i broke it) but it actually screwed in and it WORKS! Of course 40watt bulb not really bright, but gorgeous and was easy to install.
I firmly believe any review which said it was great or that they had no problem with the bulb is a fabrication for the sake of better ratings. My master electrician and I spent a whole day, four stores and hours of research on electrical industry specifications only to come up with 26 unusable bulbs, $42 and a day of work wasted, $330 wasted on an electrician to install and two pieces if trash I now have to ship back to Amazon. I am disappointed and livid.
