2) Economy, such as initial investment in lamp efficiency and long-term operating costs;

3) Special environmental conditions such as dust, humidity, vibration and chemical corrosion environment in a fire hazard or explosion hazard environment;

4) The shape of the lamp should be coordinated with the building.
