Abstract: A colored coating composition comprising a white base paint and at least one colored pigment in a form that can be readily mixed with the white base paint, the white base paint comprising a film-forming polymer, a liquid carrier, one or more opacifying white pigments and one or more extenders, the colored coating composition having a light reflectance value Y less than 110, and greater than that defined by the equation Y=mC+K, where 25>C>1.0, C being the chroma of the colored coating composition, m and K being empirical coefficients selected according to the type and number of the type of the at least one colored pigment, and dependant on the hue angle of the coating composition.

Abstract: The invention relates to an emergency lighting unit which is used in association with an electric discharge lamp in a fixture. The lamp has a first input terminal and a second input terminal. The emergency lighting unit includes a transformer which has two closely coupled windings constituting the primary of the transformer and a secondary winding. First adjacent ends of the coupled windings constitute the input of the emergency lighting unit, and second adjacent ends of the coupled windings constitute the output terminals thereof. The input terminals are adapted to be connected to a source of ac power, and the output terminals are adapted to be connected to respective ones of the first and second input terminals of the lamp. A rectifier is connected across the output of the secondary winding, and a rechargeable battery is connected across the output of the rectifier to be recharged by the dc output thereof.
