Panel-Vue® and Sign-Vue® Illuminaires are the best choices to achieve the two purposes of a sign after sundown: to attract attention and to convey a message.Visibility and legibility are achieved by creating contrast; contrast between the sign and its background creates visibility while contrast between the legend and the sign face creates legibility. Hot spots and dark spots are elimated when Panel-Vue ®and Sign-Vue®II fixtures are used because extremely uniform illumination is provided over the entire sign face.
