Heat Resistant Quartz Lamp Holders for Industrial Use – China Suppliers and Factory

Our high-quality quartz lamp holders are meticulously crafted from premium purity quartz glass, designed to withstand extreme temperatures while providing exceptional insulation and light transmittance. These lamp holders are compatible with various light sources, including halogen lamps and infrared heating lamps, making them essential components in both lighting and heating equipment. As a leading manufacturer in China, our factory ensures that these products can endure high-temperature radiation and current surges, maintaining stable operation for your lighting needs.

We also offer quartz inner and outer lamp caps, which serve as critical end components for a range of quartz lamps, such as UV lamps, infrared lamps, and halogen lamps. These caps provide electrical connection, sealing, and structural support, essential for optimal performance.

The inner cap connects directly to the internal electrode or light-emitting structure, while the outer cap functions as the external part for electrical connections and mounting. As trusted suppliers of quartz lamp solutions, we are committed to delivering reliable products for your lighting applications.

Product Description

Material & Quality

Made from 99.99% high-purity fused silica, our large-diameter quartz tube is free of impurities, ensuring minimal thermal expansion and maximum resistance to thermal shock (can withstand rapid temperature changes from -20℃ to 1200℃). It is non-toxic, non-porous, and resistant to most acids (except hydrofluoric acid) and alkaline solutions, making it suitable for corrosive chemical processing.

Core Advantages

Superior thermal stability: Operates continuously at 1100℃, short-term use up to 1450℃
Excellent mechanical strength: High compressive strength and impact resistance, cracking during installation and use
Customization support: Cut-to-length, flanged ends, and drilled holes available per customer drawings
Long service life: Resists aging and oxidation even under prolonged high-temperature exposure
