Question: What wattage does an E12 bulb convert to? Are E12s long lasting? I assume they are somewhat $$
Document: Great little side lamp for the bed so I can turn on a light without going across the room. It is a cord model with a switch and it uses a small size bulb. The bulb does NOT come with the fixture. It takes a Candelabra E12 bulb up to 40 watts. For safely mounting, use size 8 screws and good anchors or it will pull off the wall. I used special drywall anchors, predrilling with a small drill so they fit snug, straight, and tight.
I bought 2 of these for my master bedroom but I had to get bulbs with the mini connector. So I got the Ikea Sparsam E12 7 Watt Bulbs. They work great!
This lamp is great for reading in bed. It gives a nice soft glow. I looked a long time for a lamp like this.
This lamp was very cute, but only took a 40 watt bulb. I had wanted it for a reading lamp, but 40 watts just isn't enough.
This item was difficult to install. It also did not come with a bulb, and as it is a special type bulb, I have not been able to locate one to purchase. I have not been able to use this lamp at all. I am dissappointed.
I ordered two of these - they arrived quickly and are just perfect for what I wanted. BIG PROBLEM:  Cannot find a bulb to fit. Not in stores, not on-line, not anywhere! I'm getting desparate.
I was expecting a bigger lamp that took a regular sized bulb. It works well and I will use it until I find a bigger one,  A wall lamp with an attached cord is hard to find.
These were a snap to put up and look great on each side of our bed. The lightbulb is a strange size but works well except for the time it takes to get to full strength. I do wish these took a standard base bulb but I'm sure this size will be easier to get in the future.
This was junk. I'm pretty sure I received one that had already been returned. The lamp shade had a crack in it and a large smudge of dirt on the bottom. Also, the threading for the light bulb was all messed up and misshapen. I made sure to order the correct bulbs and neither of the two would screw into the lamp. Thankfully Amazon rules and the return was no problem.
This lamp is perfect for beside my bed. The bulb takes a minute to get bright but once it brightens up its nice. I'd buy it again.
Answer: no
