Light gallery react6/19/2023 ![]() To get a noticeable contrast you need a minimum ratio of 3:1 of accent light to general light. Therefore if you are lighting highly responsive, sensitive pieces like watercolours, SLL recommend a maximum of 50lux for up to 300 hours a year. High responsivity – LUX 50 – LUX HOURS 15,000 Medium responsivity – LUX 50 – LUX HOURS: 150,000 Low responsivity – LUX: 200 – LUX HOURS: 600,000 Irresponsive – LUX: no limit – LUX HOURS: no limit The Society of Light and Lighting offer advice in their CIBSE lighting guide 8 (LG8) of Illuminaince exposure for different types of pictures – see section 5.2: Less light for limited periods reduces the likelihood of damage to a painting. Considering lux-hours is essential for delicate pieces of artwork such as watercolours. ![]() The lower the general light levels the less accent light you need. Many galleries have relatively low levels of illumination to limit their artworks exposure to light (Lux-hours). This ratio is important and depends on several factors. We know light can guide and focus our attention, so light onto artwork needs to be brighter than its immediate surrounding area. Many light sources (especially the sun) emit these damaging wavelengths, so it’s important to choose light sources carefully. Combined, the colour spectrum produces white light, but just outside of this visible spectrum is ultraviolet and infrared radiation. Light is electromagnetic radiation, a form of energy. Many of these things still apply when lighting artwork at home. In this post lighting design studio look at the important factors you really need to consider when lighting artwork in a gallery. Lighting artwork is largely about preservation as well as aesthetics. ![]() So correct specification of lighting can be very important. In some of the galleries we light, the paintings are priceless, pieces from great masters that can never be replaced.

Light can react with pigmentation and materials causing premature aging and degradation to the artwork. If done incorrectly, lighting can damage a painting. If art lighting is done correctly, colours and textures come to life. There are an array of things to consider when lighting artwork. ![]()
