Triangle Capillary Glass Rod Concaved Shape for Chandelier Lamp

Product Description

High Borosilicate Glass Tubes for LED Tri-Proof Lights
Ideal raw material for waterproof, dustproof & anti-corrosion tri-proof lamps.

• Strong thermal shock resistance, anti-explosion under high & low temperature
• High light transmittance, uniform light output
• Custom size, clear/frosted surface available
• Durable for factory, basement, warehouse, underground parking lots

Our high borosilicate glass tubes are specially developed to support LED tri-proof lighting fixtures, built to withstand harsh industrial environments with reliable waterproof, dustproof and anti-corrosion performance.

Featuring outstanding thermal shock resistance, the tubes will not crack under drastic temperature changes common in damp, dusty workshops, parking lots and factory workshops. High light transmittance delivers stable, bright illumination with minimal light loss.

Available in customizable diameters, wall thicknesses and lengths to fit various tri-proof lamp housings. Clear, frosted and customized surface finishes are all optional to meet different lighting softness requirements. The sturdy glass structure lowers breakage risk during production, transportation and long-term on-site use, greatly extending the service life of your tri-proof lights.
