	Daylight is present at a particular location, to some degree, whenever the sun is above the horizon at that location. (This is true for slightly more than 50% of the Earth at any given time. For an explanation of why it is not exactly half, see here). However, the outdoor illuminance can vary from 120,000 lux for direct sunlight at noon, which may cause eye pain, to less than 5 lux for thick storm clouds with the sun at the horizon (even <1 lux for the most extreme case), which may make shadows from distant street lights visible. It may be darker under unusual circumstances such as a solar eclipse or very high levels of atmospheric smoke (See New England's Dark Day), dust,^[1] or volcanic ash.^[2] ^{From http://en.wikipedia.org/wiki/Daylight} Also see http://en.wikipedia.org/wiki/Lux or http://www.engineeringtoolbox.com/light-level-rooms-d_708.html __________________ Common Sense Dictates

	Chart given by Lyn is a great starting point. Check for local legislation. Be mindful of lighting to escape routes and in particular stairs. You need very little ligt to see by. Consider a windowless room and a single candle. Your night vision kicks in and you can see. You need to make certain calls here. If a technician needs to read a gauge or operate a panel he will need maybe 100 lux. For walking areas this can be reduced to maybe 10 to 20 lux. Escape routes can be down to 1 or 2 lux but again give consideration to making a plant safe before you leave it. If you need to shut things down you may need a 100 lux in that area. If it is an industrial situation watch for hazardous areas - explosive areas etc.
