These shells are popular for their affordability and ability to minimize glare.

• Edison Bulb Shell:

  The Edison bulb shell has a vintage feel, showcasing the filament design. It is mostly made of glass and has a decorative appeal. The exposed filament design allows for a warm, inviting glow when the bulb is lit. Also, the shell's intricate patterns and designs create an aesthetic focal point in any room even when the light is off.

• Decorative Bulb Shell:

  These bulb shells are specifically designed to enhance the visual impact of a light fixture. They come in different shapes and sizes, such as teardrop. The filament in these bulbs can be arranged in spiral, straight, or candelabra styles. Additionally, they can have colored or patterned glass that adds a unique touch to the lighting.

Function and feature of bulb shell

Plastic bulb shells are primarily used as a protective casing for light bulbs. They serve both functional and aesthetic purposes. Below are some of the features of the bulb shell:

• Material

  The bulb shells are made from different materials. This includes glass or various types of plastics like acrylic or polycarbonate. The materials are usually chosen for their transparency or translucency. This allows light to pass through effectively.

• Shape and Design

  The bulb shells are designed to enclose the light source. They come in various shapes and sizes. This depends on the type of bulb they are meant to fit. Common designs include the traditional incandescent bulb shape, as well as more modern, compact fluorescent, and LED shapes.

• Durability

  Many bulb shells are constructed to be impact-resistant. This is especially true for those made from polycarbonate. This ensures that the bulbs can withstand bumps and accidental falls. They are also made to be heat resistant. The bulbs can dissipate heat without any damage.

• Light Diffusion

  Some bulb shells have a frosted or textured surface. This helps to diffuse light evenly. The feature reduces glare and creates a softer illumination. Clear bulbs, on the other hand, allow for a more focused light output.

• UV Coating

  To enhance the durability of the bulb shells, they are coated with UV resistant materials. This prevents yellowing and maintains the clarity of the shell over time, especially in bulbs that are used outdoors.

• Base Integration

  The bulb shell is designed to integrate seamlessly with the base of the light bulb. The base is usually the metal part that screws into a socket (like E27 bulb). It provides a safe and secure enclosure for the filament or LED components, as well as for the electronics in the case of more modern bulbs.

• Electrical Insulation

  Some bulb shells offer electrical insulation. This prevents users from accidental electrical shocks when touching certain parts of the bulb, especially the base when it is connected to a socket.
