1. Depending on light intensity

Light intensity High specifications: Generally speaking, high -tough steam body filling is the most economic development.

Outside: When the lighting appliance must be placed in all the normal categories of the operator, the low -chromatographic lamp source such as the fluorescent lamp should be used.

Low light intensity specifications: All light sources can be considered.

Outside: During medium or higher installation, high tough discharge lamps are generally best selected.

2. Maintenance feasibility analysis

High -tough gas discharge lights should be used in a natural environment that is difficult to maintain, and due to the long service life of the lamp source.

3. Working time

It is not necessary to go to work every year for 2000 hours. The use of high -tough gas discharge lamps and fluorescent lamps is relatively economic development. At the time of the 2000s of hours of work every year, solar lights are more economical.

4. Other elements

When the cost of kinetic energy is high, the high tough gas discharge lights are generally the most economical.

Safety type: Emergency lighting and venues that must be converted frequently, because high -tough gas discharge lights are slowly started and generally not adopted.
