Lovely light bulb with extremely pleasant for eyes effect of lit up coils inside the bulb. I saw these bulbs for the first time in a fancy restaurant when I was on holidays, since then I was looking for it. It gives a warm feeling to the room with nice yellow light. Inside the bulb, you will see how the light brightens up. The vintage Edison lightbulb has a beautiful shape and is made of glass so when screwing into the lampshade you have to be careful.
