That makes brightness complaints easier to trigger if interior lighting is not managed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"manage-interior-lighting-at-night\">Manage interior lighting at night<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If the store interior is very bright, people outside are already glare-adapted to brightness\u2014and your display may feel overly strong by comparison, especially if reflections are present.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Operationally:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>reduce interior luminaires near glass after hours,<\/li>\n\n\n\n<li>use blinds\/lighting zones,<\/li>\n\n\n\n<li>avoid spotlight beams aimed at the glass plane.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"tune-for-perceived-brightness-not-just-measured-brightness\">Tune for perceived brightness, not just measured brightness<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Two installations can measure similarly but feel different:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>one has a dark street background (sign feels intense),<\/li>\n\n\n\n<li>one has bright urban background (sign feels moderate).<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">So your tuning must include&nbsp;<strong>field observation<\/strong>&nbsp;from sensitive viewpoints\u2014alongside meter readings.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"align-stakeholders-early\">Align stakeholders early<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you\u2019re quoting and commissioning a glass-facing project, decide upfront:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>What is the night behavior policy?
