They solve different problems: <strong>slim is about how much the fixture exists in the room, wide is about how much light leaves it and how much metal carries the heat.<\/strong> The figure that decides whether a slim body is usable is not its width \u2014 it is the strip that has to go inside.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does width actually change?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Four things, and they move in different directions.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th><\/th><th>Slim body<\/th><th>Wide body<\/th><\/tr><\/thead><tbody><tr><td>Visual presence<\/td><td>A line, or almost nothing<\/td><td>A visible architectural element<\/td><\/tr><tr><td>Aperture<\/td><td>Narrow \u2014 the light line is thin<\/td><td>Wide \u2014 the line is a band<\/td><\/tr><tr><td>Heat capacity<\/td><td>Limited by section mass<\/td><td>More metal, more spreading<\/td><\/tr><tr><td>Strip compatibility<\/td><td>Narrow strips only<\/td><td>Wider strips, multi-row possible<\/td><\/tr><tr><td>Mounting depth needed<\/td><td>Shallow<\/td><td>Deeper, or surface-mounted<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The first two are what people mean when they compare slim and wide. The last two determine whether the comparison is even available.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/hlled.com\/wp-content\/uploads\/2024\/07\/A092.png\" alt=\"HL-A092 slim profile, 35 by 6 mm, a shallow body for narrow rebates\" title=\"\"><figcaption class=\"wp-element-caption\">HL-A092 \u2014 35 \u00d7 6 mm. 6 mm deep is what makes a rebate detail possible at all.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Where does slim win?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Where the fixture should disappear<\/strong>,\u00a0an 8\u201312 mm body in a reveal reads as a line of light rather than a fitting. That is the whole point, and no wide body achieves it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Where the detail is shallow<\/strong>,\u00a0a 5 mm-deep rebate will not accommodate a 20 mm body. Slim is not a preference there; it is the only option.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Where the substrate is weak<\/strong>,\u00a0a thin panel or a furniture carcass carries a small section without thought.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Where the run is short and decorative<\/strong>,\u00a0a shelf edge, a niche, a wardrobe interior \u2014 output is not the driver.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/hlled.com\/wp-content\/uploads\/2025\/09\/A010-1-768x768.jpg\" alt=\"HL-A010 wide profile, 78 mm outer width, a body that carries a broad light band\" title=\"\"><figcaption class=\"wp-element-caption\">HL-A010 \u2014 78 mm wide. A band, not a line \u2014 and only if the strip fills the aperture.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Where does wide win?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Where the light line is the design<\/strong>,\u00a0a 60 mm body with a wide diffuser gives a band of light, not a line, in a reception ceiling or a retail soffit; that is the intent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Where the strip is wide<\/strong>,\u00a0a 25 mm or 32 mm strip requires a body to hold it. Slim bodies do not go that wide \u2014 the physical channel has to clear the PCB.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Where the load is high<\/strong>,\u00a0more metal means greater thermal mass and more exposed surface area. A high-output or multi-row strip in a slim body will run hotter than the same strip in a wide one.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Where the body has to span<\/strong>,\u00a0a wider, deeper section is stiffer, so it sags less between fixings \u2014 which matters on a suspended or ceiling run.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why isn&#8217;t a wide body automatically brighter?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Because the light line is set by the aperture the diffuser covers, and the strip behind it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Put a single 12 mm strip into a 76 mm body, and the lit portion occupies a fraction of the aperture: bright in the middle, dim at the edges. That reads as a soft band rather than a crisp line, and the extra metal does nothing for output.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A wide body only produces more light if it carries more emitter \u2014 a wider strip, two strips side by side, or a multi-row board. Otherwise it is a wide housing with a narrow light line, which is a valid look but not a brighter one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What decides whether a slim body is usable?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Not the width. The strip and the load.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Three constraints, in order:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>PCB width.<\/strong> A slim body takes a narrow strip \u2014 typically 4 to 10 mm in our range. If the project needs a 16 mm strip, the slim option does not exist regardless of how it looks.<\/li>\n\n\n\n<li><strong>Watt per meter.<\/strong> A shallow, narrow section has little mass to absorb heat. Above moderate output, the body runs hot, and the strip&#8217;s life is affected.<\/li>\n\n\n\n<li><strong>Diffusion.<\/strong> A shallow cavity has little mixing distance, so a slim body with a clear cover shows dots at close range. Slim plus a high-density strip plus an opal cover is the combination that works.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/hlled.com\/wp-content\/uploads\/2024\/07\/A065.png\" alt=\"HL-A065 profile, 15.5 by 12.5 mm, a mid-size body\" title=\"\"><figcaption class=\"wp-element-caption\">HL-A065 \u2014 15.5 \u00d7 12.5 mm. The middle of the range is where most projects land.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What does our range actually look like?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The distribution is not what most people expect \u2014 the wide end is the larger group.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Outer width<\/th><th>Perfiles<\/th><\/tr><\/thead><tbody><tr><td>Up to 12 mm<\/td><td>11<\/td><\/tr><tr><td>12\u201320 mm<\/td><td>32<\/td><\/tr><tr><td>20\u201335 mm<\/td><td>48<\/td><\/tr><tr><td>35\u201360 mm<\/td><td>59<\/td><\/tr><tr><td>Over 60 mm<\/td><td>68<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Range: 8 mm to 264.6 mm outer width, median 45 mm. Strip compatibility runs from a 4 mm PCB to an 185 mm board.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So &#8220;slim&#8221; is the specialist end of the range, not the default. Most of what we make is 20 mm and up, because most projects are lighting a room rather than drawing a line in a ceiling.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/hlled.com\/wp-content\/uploads\/2024\/06\/HL-A044.png\" alt=\"HL-A044 wide body, 52.8 by 20.7 mm, taking a 21 mm strip\" title=\"\"><figcaption class=\"wp-element-caption\">HL-A044 \u2014 52.8 \u00d7 20.7 mm. Wide and deep: the opposite corner of the same decision.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Is slim the same as shallow?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">No, and confusing the two causes more specification errors than any other pair of terms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Width<\/strong> is measured across the section \u2014 how much the body occupies horizontally. <strong>Depth<\/strong> is measured into it \u2014 how far the diffuser sits from the strip.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A body can be narrow and deep (a 12 mm-wide, 20 mm-deep slot profile) or wide and shallow (a 60 mm-wide, 8 mm-deep surface body). The two dimensions do different jobs:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Narrow affects how little the fixture shows.<\/li>\n\n\n\n<li>Shallow affects how little it takes out of the room, and how little distance the light has to mix.<\/li>\n\n\n\n<li>Deep improves diffusion and adds mass; it does not make the body visually wider.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">So a project that needs a discreet line and a dot-free output needs <strong>narrow and deep<\/strong>, not simply slim. A genuinely shallow body is a different specification, and it usually means accepting either a wider line or a visible dot pattern.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How do you decide?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Four questions, in this order:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What is the strip?<\/strong> Its PCB width sets the minimum body. This comes first because it is not negotiable.<\/li>\n\n\n\n<li><strong>What load will it carry?<\/strong> That sets the minimum mass and, therefore, a minimum section.<\/li>\n\n\n\n<li><strong>How much room is there?<\/strong> Slot depth and available clearance set the maximum.<\/li>\n\n\n\n<li><strong>What should the line look like?<\/strong> Thin line or band \u2014 this is the choice that is actually aesthetic.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Only the fourth question is about slim versus wide. The first three usually narrow it to two or three profiles before aesthetics gets a vote.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Our <a href=\"\/es\/led-aluminum-profile\/ultra-slim\/\" target=\"_blank\">ultra-slim collection<\/a> is the slim end, and the <a href=\"\/es\/led-profiles\/\" target=\"_blank\">full range<\/a> lists outer width, outer height, and PCB width for all 219 profiles, so the first three questions can be answered from the drawing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is a slim profile always dimmer?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. The strip sets output, not the housing. A slim body with a high-density strip can be brighter than a wide body with a sparse one \u2014 it just has less capacity to carry the heat that comes with it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I put a wide strip in a slim body?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No, and this is the error that stops installations. The channel has to clear the PCB. If the strip is 12 mm, the body has to take 12 mm, which rules out the slimmest sections entirely.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does a wide body look more professional?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It looks more architectural, which is different. A wide body announces itself; a slim one disappears. Which is appropriate depends on whether the lighting is meant to be part of the interior or part of the architecture.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the practical limit for a slim body on load?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It depends on the section and the mounting, but the pattern is consistent: shallow bodies with little exposed surface are the first to run hot. If the body is too hot to keep a finger on after an hour, the section or the strip is wrong for the detail.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can slim and wide profiles be used in the same room?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, and often they should be \u2014 a slim line in a reveal and a wider band in a ceiling cove are different jobs. What does not work is switching mid-run: the two sections do not align, and the change reads as an error unless it happens at a deliberate break.<\/p>\n<style>\r\n.lwrp.link-whisper-related-posts{\r\n            \r\n            \r\n        }\r\n        .lwrp .lwrp-title{\r\n            \r\n            font-size: 20px;\r\n        }.lwrp .lwrp-description{\r\n            color: #5b5757;\r\n            \r\n\r\n        }\r\n        .lwrp .lwrp-list-container{\r\n        }\r\n        .lwrp .lwrp-list-multi-container{\r\n            display: flex;\r\n        }\r\n        .lwrp .lwrp-list-double{\r\n            width: 48%;\r\n        }\r\n        .lwrp .lwrp-list-triple{\r\n            width: 32%;\r\n        }\r\n        .lwrp .lwrp-list-row-container{\r\n            display: flex;\r\n            justify-content: space-between;\r\n        }\r\n        .lwrp .lwrp-list-row-container .lwrp-list-item{\r\n            width: calc(50% - 20px);\r\n        }\r\n        .lwrp .lwrp-list-item:not(.lwrp-no-posts-message-item){\r\n            \r\n            \r\n        }\r\n        .lwrp .lwrp-list-item img{\r\n            max-width: 100%;\r\n            height: auto;\r\n            object-fit: cover;\r\n            aspect-ratio: 1 \/ 1;\r\n        }\r\n        .lwrp .lwrp-list-item.lwrp-empty-list-item{\r\n            background: initial !important;\r\n        }\r\n        .lwrp .lwrp-list-item .lwrp-list-link .lwrp-list-link-title-text,\r\n        .lwrp .lwrp-list-item .lwrp-list-no-posts-message{\r\n            \r\n            font-size: 18px;\r\n            font-weight: 400;\r\n            \r\n        }@media screen and (max-width: 480px) {\r\n            .lwrp.link-whisper-related-posts{\r\n                \r\n                \r\n            }\r\n            .lwrp .lwrp-title{\r\n                \r\n                \r\n            }.lwrp .lwrp-description{\r\n                \r\n                \r\n            }\r\n            .lwrp .lwrp-list-multi-container{\r\n                flex-direction: column;\r\n            }\r\n            .lwrp .lwrp-list-multi-container ul.lwrp-list{\r\n                margin-top: 0px;\r\n                margin-bottom: 0px;\r\n                padding-top: 0px;\r\n                padding-bottom: 0px;\r\n            }\r\n            .lwrp .lwrp-list-double,\r\n            .lwrp .lwrp-list-triple{\r\n                width: 100%;\r\n            }\r\n            .lwrp .lwrp-list-row-container{\r\n                justify-content: initial;\r\n                flex-direction: column;\r\n            }\r\n            .lwrp .lwrp-list-row-container .lwrp-list-item{\r\n                width: 100%;\r\n            }\r\n            .lwrp .lwrp-list-item:not(.lwrp-no-posts-message-item){\r\n                \r\n                \r\n            }\r\n            .lwrp .lwrp-list-item .lwrp-list-link .lwrp-list-link-title-text,\r\n            .lwrp .lwrp-list-item .lwrp-list-no-posts-message{\r\n                \r\n                \r\n                \r\n                \r\n            };\r\n        }<\/style>\r\n<div id=\"link-whisper-related-posts-widget\" class=\"link-whisper-related-posts lwrp\">\r\n            <h3 class=\"lwrp-title\">Puestos relacionados<\/h3>    \r\n        <div class=\"lwrp-list-container\">\r\n                                            <div class=\"lwrp-list-multi-container\">\r\n                    <ul class=\"lwrp-list lwrp-list-double lwrp-list-left\">\r\n                        <li class=\"lwrp-list-item\"><a href=\"https:\/\/hlled.com\/es\/videos\/ultra-thin-surface-mounted-linear-light\/\" class=\"lwrp-list-link\"><span class=\"lwrp-list-link-title-text\">HL-CA011-L10 Patented Ultra-Thin Surface Mounted Linear Light: Video &amp; Guide<\/span><\/a><\/li><li class=\"lwrp-list-item\"><a href=\"https:\/\/hlled.com\/es\/knowledge\/how-much-watt-led-bulb-required-for-a-room\/\" class=\"lwrp-list-link\"><span class=\"lwrp-list-link-title-text\">cu\u00e1ntos vatios necesita una bombilla led para una habitaci\u00f3n\uff1f<\/span><\/a><\/li>                    <\/ul>\r\n                    <ul class=\"lwrp-list lwrp-list-double lwrp-list-right\">\r\n                        <li class=\"lwrp-list-item\"><a href=\"https:\/\/hlled.com\/es\/knowledge\/2x4-led-panel-for-your-office-lighting-solutions\/\" class=\"lwrp-list-link\"><span class=\"lwrp-list-link-title-text\">5 razones para elegir un panel LED de 2\u00d74 para la iluminaci\u00f3n de su oficina<\/span><\/a><\/li><li class=\"lwrp-list-item\"><a href=\"https:\/\/hlled.com\/es\/how-to\/whats-the-corner-profile-for-led-strip\/\" class=\"lwrp-list-link\"><span class=\"lwrp-list-link-title-text\">\u00bfCu\u00e1l es el perfil de esquina para la tira LED?<\/span><\/a><\/li>                    <\/ul>\r\n                <\/div>\r\n                        <\/div>\r\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Slim is about presence, wide is about aperture and heat.
