Southwest already serves more domestic passengers than any other airline, but near-international markets like Latin America and the Caribbean represent a big potential growth opportunity for the company. Southwest Airlines is breaking ground on a new international terminal in Houston.The Houston terminal is a big part of Southwest's international expansion plans. Houston is the fifth-largest U.S. metropolitan area, so it has plenty of local traffic, and it is well located to serve as a Latin American gateway.outhwest already serves more domestic passengers than any other airline, but near-international markets like Latin America and the Caribbean represent a big potential growth opportunity for the company.

The unit of measuring the brightness-or to use the precise scientific terminology, illuminance-in SI system of measurement is lux or lumen per square meter.Illuminance is measured in foot candles. One foot-candle is equal to 10.76 lux. Please note that lumen is the measure of total light emitted by a source of light.he total amount of visible light is measured in units of lumens. How bright it appears when it falls on a surface area is illuminance. When the same luminous flux falls over a larger area it will appear to be less bright. 1 lx = 1 lm/m^2 which in terms of the basic SI units is 1 cd*sr*m^-2.
A lux meter is a device for measuring brightness, specifically, the intensity with which the brightness appears to the human eye. This is different than measurements of the actual light energy produced by or reflected from an object or light source. lux meter works by using a photo cell to capture light. The meter then converts this light to an electrical current, and measuring this current allows the device to calculate the lux value of the light it captured. Ad. The most common use of this type of meter is in photography and video filming.
