The <strong>designer ceiling light<\/strong> represents, within this evolution, a typology that combines architectural integration with sculptural presence: a luminaire that adheres to the upper plane without sacrificing visual character. When a project demands ceiling lighting that engages with the geometry of the space \u2014without the drop of a pendant or the invisibility of a recessed fitting\u2014 the ceiling light emerges as the precise response.<\/p>\n\n\n\n<p>Our <a href=\"https:\/\/www.insolitbcn.com\/en\/designer-ceiling-lights\/\"><strong>collection of designer ceiling lights<\/strong><\/a> explores this typology through the TR Ceiling collection, designed by <strong>Josep Llu\u00eds Xucl\u00e0<\/strong>. Two variants \u2014<strong>TR Ceiling Down<\/strong> and <strong>TR Ceiling Up<\/strong>\u2014 share the same circular formal vocabulary yet deliver two complementary lighting behaviours: direct and indirect light. Entirely manufactured in Barcelona from <strong>extruded and curved aluminium<\/strong>, with proprietary <strong>flexible PCB LED<\/strong> technology and a <strong>CRI of 90<\/strong>, these luminaires embody the synthesis of industrial precision and high-level craftsmanship that defines our identity.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>TR Ceiling Down: Direct Light with Sculptural Presence<\/strong><\/h2>\n\n\n\n<p>The <a href=\"https:\/\/www.insolitbcn.com\/en\/product\/tr-ceiling-down\/\"><strong>TR Ceiling Down<\/strong><\/a> is a circular <strong>designer ceiling light<\/strong> that projects light downward, directly illuminating the work surface or activity plane. Its <strong>extruded and curved aluminium<\/strong> profile generates a clean circumference, a continuous stroke that dialogues with ceiling architecture without competing with it.<\/p>\n\n\n\n<p>The <strong>gel polycarbonate diffuser<\/strong> softens the LED emission and eliminates any glare, ensuring <strong>maximum visual comfort<\/strong> through its <strong>Colour Rendering Index of 90<\/strong>. This level of chromatic fidelity proves essential in spaces where accurate colour perception is decisive: art galleries, professional work areas, high-end <em>hospitality<\/em> or residences where every material and finish must be appreciated with complete naturalness.<\/p>\n\n\n\n<p>Installation is achieved via <strong>12 or 20 cm rods<\/strong> that separate the luminaire body from the ceiling plane, creating a subtle air gap that reinforces the perception of lightness. The <strong>independent circular canopy<\/strong> for surface mounting allows a clean, discreet fixing adaptable to any ceiling type.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>TR Ceiling Up: Indirect Lighting and Enveloping Atmospheres<\/strong><\/h2>\n\n\n\n<p>The <a href=\"https:\/\/www.insolitbcn.com\/en\/product\/tr-ceiling-up\/\"><strong>TR Ceiling Up<\/strong><\/a> reverses the direction of light emission: it projects light upward onto the ceiling, transforming it into a large reflector that returns diffuse, enveloping illumination free of harsh shadows. It is a <strong>designer ceiling light<\/strong> conceived to create atmospheres of quiet elegance, where the light source disappears and the space seems to glow from within.<\/p>\n\n\n\n<p>This <strong>indirect lighting<\/strong> mode is particularly valued in interior design projects seeking <strong>ambient comfort without visible light sources<\/strong>: residential living rooms, hotel lobbies, meeting rooms or waiting areas where visual serenity is part of the experience. By reflecting light off the ceiling plane, the TR Ceiling Up enhances the perception of height and spaciousness \u2014a lighting technique that lighting designers frequently employ to transform the perceived volumetry of a space.<\/p>\n\n\n\n<p>The TR Ceiling Up shares with its Down counterpart the same material rigour: <strong>extruded and curved aluminium<\/strong>, <strong>gel polycarbonate diffuser<\/strong> and <strong>flexible PCB LED<\/strong> specifically designed by Ins\u00f2lit for the TR collection. This constructive coherence between both variants allows their integration within the same project, with the certainty that the formal language will remain identical.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Four Diameters, Five Finishes: A Ceiling Light for Every Scale<\/strong><\/h2>\n\n\n\n<p>Both the TR Ceiling Down and TR Ceiling Up are available in <strong>four diameters<\/strong> suited to diverse architectural scales: <strong>\u00d850 cm (32 W \/ 1,693 lm)<\/strong>, <strong>\u00d870 cm (48 W \/ 2,540 lm)<\/strong>, <strong>\u00d8100 cm (70 W \/ 3,683 lm)<\/strong> and <strong>\u00d8120 cm (90 W \/ 4,733 lm)<\/strong>. This range enables specification of the appropriate luminaire for a compact office as well as a double-height foyer.<\/p>\n\n\n\n<p>The palette of finishes \u2014<strong>white, black, gold, bronze and graphite<\/strong>\u2014 has been conceived to dialogue with the most frequent materialities in contemporary interior architecture. White integrates seamlessly into light ceilings; black provides contrast and graphic definition; gold and bronze introduce a material warmth evocative of craftsmanship; graphite offers a sophisticated neutrality that works in both residential and <em>contract<\/em> contexts.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Light Control and Colour Temperature: Precision at the Service of the Project<\/strong><\/h2>\n\n\n\n<p>Each <strong>designer ceiling light<\/strong> in the TR Ceiling collection is offered in three <strong>colour temperatures<\/strong> \u2014<strong>2,700 K, 3,000 K and 4,000 K<\/strong>\u2014 to adapt the light tonality to the functional requirements of the space. The 2,700 K setting produces a warm light ideal for residential and <em>hospitality<\/em> environments; the 3,000 K offers a neutral-warm balance suited to work areas and commercial spaces; the 4,000 K delivers a cooler, more stimulating light, optimal for technical or healthcare settings.<\/p>\n\n\n\n<p>The dimming system is equally versatile. The luminaires support <strong>TRIAC, DALI\/Push, 1-10V and Casambi<\/strong> control, ensuring integration into any home automation or professional lighting management ecosystem. The <strong>Casambi<\/strong> option proves especially interesting for projects seeking wireless dimming without additional wiring, simplifying installation and broadening the possibilities of scenographic control.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Layered Compositions: When a Ceiling Light Becomes an Installation<\/strong><\/h2>\n\n\n\n<p>One of the most distinctive qualities of the TR Ceiling collection is its capacity to generate <strong>layered multi-unit compositions<\/strong>. Thanks to the rod system at varying heights, several ceiling lights of different diameters can overlap at a single ceiling point, creating circular constellations that transform an individual <strong>designer ceiling light<\/strong> into a true <strong>bespoke lighting installation<\/strong>.<\/p>\n\n\n\n<p>This compositional possibility proves particularly powerful in lobbies, restaurants, conference rooms or any space demanding a luminous focal point with sculptural presence. By combining TR Ceiling Down and TR Ceiling Up units within a single composition, the specifier can design a piece that simultaneously provides <strong>direct and indirect illumination<\/strong>, achieving a lighting richness that is difficult to attain with a single luminaire typology.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Barcelona Craftsmanship for Uncompromising Projects<\/strong><\/h2>\n\n\n\n<p>The TR Ceiling collection embodies Ins\u00f2lit&#8217;s philosophy: luminaires born from the dialogue between signature design and high-level artisanal manufacture in Barcelona. Each <strong>designer ceiling light<\/strong> in this family is <strong>fully customisable<\/strong> \u2014in diameter, finish, colour temperature and control system\u2014 enabling architects and interior designers to specify a solution that precisely meets the formal and lighting requirements of every project.Designed by <strong>Josep Llu\u00eds Xucl\u00e0<\/strong> and entirely manufactured in our Barcelona workshop, the TR Ceiling Down and TR Ceiling Up luminaires demonstrate that a ceiling light can be far more than a point of light: it can be the piece that defines the luminous identity of a space.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ins\u00f2lit&#8217;s TR Ceiling collection offers circular designer ceiling lights in extruded aluminium, with direct or indirect light and high colour rendering LED technology.<\/p>\n","protected":false},"author":3,"featured_media":23929,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_yoast_wpseo_title":"","_yoast_wpseo_metadesc":"Designer ceiling light in extruded aluminium with high-CRI LED.
