Overview:                                  
The newly released Digital Illuminance Meter LX1330B is a lux meter with wide measuring range and lots of nice features. A lux meter is used for checking the level of illuminance, the light falling on a surface, It is defined as: 'the density of the luminous flux incident on a surface'. It is the quotient of the luminous flux by the area of the surface when the latter is uniformly illuminated.. This convenient gadget is widely used in many areas such as construction, inspection, photography, greenhouse gardening and etc
The LX1330B can measure from 0 up to 200,000 lux, you can switch the units between lux and footcandle by simply pressing a button. It's powered by a 9V battery, which last for 200 hours or even longer. Other nice features include data hold, auto zero and more.

The Model LX1330B can be measured with two illuminance scales Lux and FC
1 footcandle = 10.76391 lux

Foot-candle (sometimes foot candle; abbreviated fc, lm/ft², or sometimes ft-c) . The unit is defined as the amount of illumination the inside surface of a 1-foot radius sphere would be receiving if there were a uniform point source of one candela in the exact center of the sphere. Alternatively, it can be defined as the illuminance on a 1-square foot surface of which there is a uniformly distributed flux of one lumen. This can be thought of as the amount of light that actually falls on a given surface. The foot-candle is equal to one lumen per square foot.
