1. Lamp shell is made of aluminum alloy high pressure diecast with dandy structure, strong and solid as well as corrosion resistant.

2. The translucent lampshade is made of hard borax glass pressed under

3. Pressure with transmission over85%; excellent impact resistance with tender and smooth rays through prismatic deflection and with imported high purity aluminum reflector with surface treated by oxidation in order to assure the high output of light flux while having the reflection rate reduced and weakened.

4. Modernized type of silicon rubber air-tight seal, high-temperature resistance above 250℃or over which effectively protect silicon rubber from aging, long-term warranted protection grade reaching up to IP65.

5. Surface of the lamps and lanterns is treated by static electricity spray plastics, high-temperature resistant with good climate resistant: nice looking and endurable properties.

6.  High-temperature resistant and high-pressure resistant silicon rubber wires are adopted.

7. Places suitable for use: Suitable to be used for illumination for subway(metro), tunnel, bridge apertures, culverts ets.
