Lux in Wigton

We were intrigued by the name of the new tanning salon in Wigton. Lux is the SI unit for light received, as perceived by the human eye. It's a measure of the intensity of the light in Watts per square metre but factored to account for the fact that human eyes perceive some wavelengths as more intense than others. Hence the same Watts per square metre in yellow would have a higher value in lux than red. Now the name of the salon might be short for luxury but since sunlight for suntans could be measured in lux, I think it's an awesome name.
