Advantages of Lux Light Meter | disadvantages of Lux Light Meter
This page covers advantages and disadvantages of Lux Light Meter. It mentions Lux Light Meter advantages or benefits and Lux Light Meter disadvantages or drawbacks.
A Light meter measures amount of light incident on the surface in lumens/m2. It is also known as illuminance meter or lux meter. A basic meter uses silicon photodiode mounted in the cavity under white translucent cap made of plastic.
The photodiode and associated electronic circuits of a light meter produces electrical current proportional to amount of light falling on active area of diode. Meter will display illuminance in units of either lux or foot-candles.
Benefits or advantages of Lux Light Meter
Following are the benefits or advantages of Lux Light Meter:
➨The light meters or lux meters are inexpensive.
➨As it is easy to measue illuminance, light meters are very simple in construction.
Drawbacks or disadvantages of Lux Light Meter
Following are the disadvantages of Lux Light Meter:
➨It is difficult to compare illuminance products based on just illuminance measurements. Other measurement parameters are also needed to have proper comparison.
➨The measurement of lux requires other information parameters such as orientation of lamp, distance, task plane area etc.
