1. The enclosure is moulded by the high strength aluminum alloy for one time, which has high strength, fine explosion-proof functions. Its exterior has sprayed with plastic by high pressure static after shot blasting at high speed. It has strong adhesion of plastic powder and great anti-corrosive performance. Outer fasteners are made of stainless steel.

2. It can be rotated 360°horizontally and adjusted in the range of +90°～－60°.

3. Focusing structure is in the lamp with Ⅱtype,and it can adjust the long distance and short distance. The reflect should get special software design of distribution for two times, and it can have the confirmation of actual test. After treating with high purity aluminum, it has great reflection and spotlight.

4. Using in the petroleum platform,tanker,ships and so on,it has fine water proof function.

5. Wiring with cables.

1. In accordance with the specifications of the meaning of the rules and regulations to choose one by one, and in the model specifications after the increase of explosion-proof mark. Concrete expression is: "product model - specification code + explosion-proof mark + order quantity". Such as the need for dust explosion-proof high-pressure sodium lamp 400W explosion-proof cast light with ballast, ordering the number of 20 sets, the product model specifications: "Model: BSD4 - Specifications: N400IZ + Ex tD A21 IP66 T195 ℃"

2. If there are some special requirements, it should be pointed as ordering.
