Gestalten Book Lux: Lamps and Lights | fly-pitcher design

It seems spectacularly unfair that the longest day of the year for us is right at the beginning of summer. Of course, there are many great things about winter but the lack of light and warmth is certainly not one of them. Aside from having an amusingly accurate acronym, SAD can have a huge impact on our health. In fact, according to a report from The Weather Channel and YouGov, 29 per cent of the UK population suffers from SAD and a huge 66 per cent of adults feel that their mood worsens as the weather does. SAD can manifest in many different ways, from lethargy and anxiety to loss of libido and trouble sleeping, meaning your constant craving for carbs and despondent mood could be bigger than the fact that you miss summer. Finding ways to combat it is key to your mental and physical health through the winter. One of the best options for this is to invest in a SAD lamp — a lamp specifically designed to target the symptoms of SAD.

The lux symbol: lx is the SI derived unit of illuminance and luminous emittance , measuring luminous flux per unit area. In photometry , this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watt per square metre , but with the power at each wavelength weighted according to the luminosity function , a standardized model of human visual brightness perception. In English, "lux" is used as both the singular and plural form. Illuminance is a measure of how much luminous flux is spread over a given area. One can think of luminous flux measured in lumens as a measure of the total "amount" of visible light present, and the illuminance as a measure of the intensity of illumination on a surface. A given amount of light will illuminate a surface more dimly if it is spread over a larger area, so illuminance is inversely proportional to area when the luminous flux is held constant.
