• Light goes in straight lines!
• Light will go around corners if there is something for it to reflect off.
• A well-lit dark surface remains a dark surface.
• A little light in an otherwise dark space goes a long way.
• Light will disperse according to the inverse square mathematical rule. For every doubling of the distance from the light source, the intensity of the light at those points will have reduced by a factor of 4.
• Recessed light fittings should to be seen as task lighting. They can only ever light forward. Therefore they should be positioned to maximise the illumination of lighter coloured surfaces, or directly over work spaces to reduce shadowing.
• Quality matters!
