why light bulbs are fragile
Light bulbs emit light.
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
Yes, e27 light bulbs are standard light bulbs in America. The e27 LED bulb is an indoor flood light. Review sellers to find ENERGY STAR rated light bulbs.
Yes, you can buy light bulbs.
Light bulbs are typically made out of glass, metal, and a filament material such as tungsten.
Light energy is indeed considered to be a raw material. This is because it does not need to be altered by humans to be used.

The light reactions of photosynthesis require oxygen as a raw material to produce ATP and NADPH. The dark reactions (Calvin cycle) of photosynthesis do not directly require oxygen as a raw material, but they use the ATP and NADPH produced in the light reactions. Both light and dark reactions are involved in photosynthesis, but only the light reactions require oxygen as a raw material.
Cheaper light bulbs often contain tungsten as the filament material. Tungsten is a cost-effective option for producing light bulbs because of its ability to withstand high temperatures and its long lifespan.

Water, carbon dioxide, and light.
Incandescent light bulbs do not emit much Ultraviolet light. Strip lights and compact fluorescent low energy light bulbs do. The whiteners added to white fabrics react to UV light and glow due to fluorescence.
The filament in traditional incandescent light bulbs is typically made of tungsten. Tungsten has a high melting point and is able to emit light efficiently when heated by an electric current.
Inside a light bulb, there is a filament (in incandescent bulbs), a gas (like argon in fluorescent bulbs), or a semiconductor (in LED bulbs). When electricity passes through the filament, it heats up and produces light. In fluorescent bulbs, electricity excites gas molecules, causing them to emit ultraviolet light, which is then converted to visible light by a phosphor coating. LED bulbs operate by allowing current to flow through a semiconductor, which emits light when electrons move through the material.
