The new Mastech Luxmeter LX1330B is a lux meter with a wide measuring range and practical features. Uses include solar panel testing, construction, inspection, photography, greenhouse gardening, etc.
The LX1330B can measure from 0 up to 200,000 lux, a much wider range than most handheld meters. You can also switch the units between lux and footcandle by simply pressing a button. It’s powered by a replaceable 9V battery. Other nice features include data hold, auto zero and more.

Just in case you’ve forgotten the last physics class you took…
LUX is lumens per square meter, and is analagous to Watts per square meter, with an adjustment for human eye response.
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. – (E = df / dA).
A luxmeter is used for testing the level of illumination falling on a surface.
