Hard Glass Bulbs are crafted from borosilicate glass, comprising approximately 80% SiO2 and 12% sodium borate (borax).

• High Temperature Resistance: Borosilicate glass offers exceptional resistance to high temperatures, making hard glass bulbs suitable for applications requiring heat resistance and thermal stability.
• Chemical Resistance: Hard glass bulbs exhibit high resistance to corrosion, making them ideal for environments where exposure to corrosive substances is a concern.
• Mechanical Strength: Borosilicate glass possesses high mechanical strength, ensuring durability and longevity in lighting fixtures subjected to mechanical stress.
• Thermal Stability: Hard glass bulbs maintain their structural integrity even when exposed to drastic temperature changes, minimizing the risk of breakage or deformation.
• Optical Clarity: Despite its robust nature, borosilicate glass maintains excellent optical clarity, allowing for efficient light transmission and dispersion.

Hard Glass Bulbs find essential applications in various aspects of the illumination industry.

• LED Encapsulation: Serving as protective enclosures for LED components, hard glass bulbs provide thermal stability and protection against external factors, ensuring reliable performance and longevity in LED lighting applications.
• Fluorescent Tube Housing: Hard glass bulbs serve as outer housings for fluorescent tubes, offering robust protection and optical clarity. This role contributes to efficient light transmission and longevity of fluorescent lights, particularly in commercial and industrial settings.
• Specialized LED Lighting Solutions: Hard glass bulbs are integral components in specialized LED lighting solutions, such as automotive LED headlights and industrial LED fixtures. Their high temperature resistance and durability ensure reliable operation in demanding environments, including automotive and industrial applications.
