Illumination of Signs

Sign lighting should not create shadows or glare. Use matte and non-glare finishes to ensure a glare-free surface. The surface should be smooth and illuminated to at least 200 lux but not strongly backlit.

The effectiveness of LED signage will depend on the colours chosen and the angle of the sign relative to the general lighting of the area. To achieve the best contrast, use LED signs that are white, yellow, green or light blue on a black background. Avoid using red on a black background, which is unreadable on LED signs for most people with vision loss, particularly those who are colour blind.
