I put an edison style light bulb in my lamp with the yarn wrapped lampshade since the bulb is semi-exposed, and I hoped it would cast a warm, yet not blinding glow.
It is a really pretty bulb that features an old-time carbon or tungsten filament in which you can see the loops and curves of the filament burning. Below is a better example than the above pictures I took.
Such bulbs were used at the turn of the 20th century. They come in various shapes and sizes, and really make a statement in an exposed bulb fixture or lamp. The downside to these bulbs is that they are costly, and they are not energy-efficient, making them impractical to use in multiple fixtures. They use about 40 watts of electricity and only put out about 6-10 watts, which is why you can see their swirly glow. I am really happy with the look of the bulb in my lamp, and it is in a prominent spot in my house, so I feel O.K. about the energy waste....plus I only have one.
