In most modern incandescent bulbs, part of the wire inside the bulb acts like a fuse: if a broken filament produces an electrical short inside the bulb, the fusible section of wire will melt and cut the current off to prevent damage to the supply lines. A hot glass bulb may fracture on contact with cold objects.
Edison light bulb enclosed in a cage. Edison light bulbs, also known as filament light bulbs and retroactively referred to as antique light bulbs or vintage light bulbs, are either carbon- or early tungsten-filament incandescent light bulbs, or modern bulbs that reproduce their appearance.
While halogen bulbs, like incandescent, contain a filament made of the metal tungsten, they are, in this case, encased in a quartz envelope (as glass would melt from the heat); the gas inside is ...
In its modern form, the incandescent light bulb consists of a coiled filament of tungsten sealed in a globular glass chamber, either a vacuum or full of an inert gas such as argon. When an electric current is connected, the tungsten is heated to 2,000 to 3,300 K (1,730 to 3,030 °C; 3,140 to 5,480 °F) and glows, emitting light that ...
That’s because traditional incandescent bulbs provide just 15 lumens per watt, according to light bulb manufacturer Philips. By contrast, most LED bulbs will get you 75 lumens per watt, or more.
The phase out has been referred to as "light bulb socialism".
