■ Choose imported high-quality aluminium alloy materials for die casting, which are light in weight, strong in strength and good in thermal conductivity, and adopt multiple anti-vibration structure design to ensure its long-term and medium-term safety in high-frequency vibration of subgrade, track, bridge and culvert tunnels.

■High-tech electrostatic spraying technology is used on the surface, which has good corrosion resistance and strong adhesion.

■Sealing ring is made of imported high-quality silicone rubber, which is extruded and vulcanized twice. Special sealing and surface coating treatment ensures that lamps and lanterns do not corrode and rust in damp, high temperature and other harsh environments.

■ Toughened glass with foreign advanced technology has good impact resistance and anti-glare treatment, which effectively ensures no glare in lamps and lanterns.

■The light source uses white LED light source with super-highpower and super-high brightness, which has high light efficiency and fully embodies the concept of energy saving and environmental protection.
