When selecting the type of lamps according to environmental conditions, pay attention to the environmental temperature, humidity, vibration, pollution, dust, corrosion, explosion and fire hazardous media. The following three environmental conditions are used to select lamps.

1. Lamp selection for general industrial plants

(1) In normal environments (heating or non-heating places), open lamps are generally used.

(2) For places that contain a lot of dust, but there is no danger of explosion or fire, use lamps that match the amount of dust.

The amount of dust in a dusty environment is measured by the concentration in the air (mg/m3) or the amount of sedimentation [mg/(m2·d)].
