The first digit is solids (dust), the second is liquids. <strong>IP20<\/strong> is interior-only \u2014 no protection against water. <strong>IP54<\/strong> handles splashes and damp locations. <strong>IP65<\/strong> is dust-tight and resists water jets, suitable for genuinely wet and outdoor exposure. Matching the rating to the environment is not optional \u2014 it is the difference between a five-year install and a callback.<\/p>\n<h2>Humidity and heat are the silent killers<\/h2>\n<p>Even &#8220;covered&#8221; outdoor spaces see condensation and heat buildup. Our outdoor-rated products are engineered for high-humidity environments and temperatures up to 50 degrees C, so a porte-cochere in Florida or a pool deck in Arizona stays reliable.<\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/eoslight.com\/wp-content\/uploads\/2026\/07\/sol-series-cloud-luminaire-atrium-ceiling-870x1080.png\" alt=\"SOL Series backlit ceiling panels in a semi-exterior atrium\" \/><\/p>\n<h2>The SOL Engine advantage outdoors<\/h2>\n<p>Our <a href=\"https:\/\/eoslight.com\/product\/cloud-luminaire-sol-series\/\">Cloud Luminaire SOL Series<\/a> is offered in both IP20 and IP65, so the same clean, hot-spot-free aesthetic carries from the lobby to the exterior. And for animated color outdoors, the new <a href=\"https:\/\/eoslight.com\/product\/dynamic-cloud-sol\/\">Dynamic Cloud SOL<\/a> brings fully-addressable RGBW to IP65-rated, 50-degree-C environments \u2014 a combination that simply did not exist a few years ago.<\/p>\n<h2>The takeaway<\/h2>\n<p>Indoor and outdoor backlighting are not the same product with a different sticker. Specify the IP rating for the real conditions, account for humidity and heat, and use a Class 2 power supply rated for the location.
