It is distinguished by its ultra-slim 35 mm housing height \u2014 one of the shallowest profiles in the iLed linear range \u2014 and its fully customizable length, allowing installers to match any room dimension without visible joints. The LL-A-1 belongs to the broader LL-A family, which also includes taller 75 mm and 90 mm depth variants; the A-1 model is the choice where ceiling reveal is limited or a near-flush finish is required.<\/p>\n<h2>Tech specs<\/h2>\n<ul>\n<li><strong>LED luminous efficacy:<\/strong> &gt;100 lm\/W \u2014 10W\/12W (35 mm width), 20W\/30W (55 mm width), up to 80W\/8000 lm (80 mm width)<\/li>\n<li><strong>Housing widths:<\/strong> 35 mm (LL-A 3575), 55 mm (LL-A 5575), 80 mm (LL-A 8090); all share 35 mm height for the A-1 recessed variant<\/li>\n<li><strong>Custom length:<\/strong> 1000 mm, 1500 mm, 2000 mm standard; bespoke lengths available on request<\/li>\n<li><strong>Beam angle:<\/strong> 120\u00b0 wide, uniform distribution through PC diffuser<\/li>\n<li><strong>Color options:<\/strong> Warm white, neutral white, cool white, tunable CCT (2700\u20136500K), RGB, RGBW, RGB+CCT<\/li>\n<li><strong>CRI:<\/strong> &gt;82 standard; &gt;92 available on white\/CCT variants<\/li>\n<li><strong>Input voltage:<\/strong> 220\u2013240VAC \/ 110\u2013277VAC dual-range (wide voltage)<\/li>\n<li><strong>Power factor:<\/strong> &gt;0.9<\/li>\n<li><strong>IP rating:<\/strong> IP42 \u2014 indoor use only; protected against solid objects &gt;1 mm and vertically dripping water<\/li>\n<li><strong>Electrical classification:<\/strong> Class II (double-insulated, no earth required)<\/li>\n<li><strong>Control protocols:<\/strong> DALI2, DMX512, SPI<\/li>\n<li><strong>Body &amp; diffuser:<\/strong> Extruded aluminum housing with frosted PC diffuser; white or black finish<\/li>\n<li><strong>Certifications:<\/strong> CE, RoHS, SAA<\/li>\n<li><strong>Warranty:<\/strong> 3\u20135 years<\/li>\n<\/ul>\n<h2>Slim 35 mm profile and recessed installation<\/h2>\n<p>The A-1&#8217;s defining feature is its 35 mm housing depth, significantly slimmer than the standard LL-A 75 mm and 90 mm depth variants. This makes it ideal for installations where ceiling cavity space is restricted \u2014 false ceilings with limited drop, retrofit projects where the existing ceiling plane must be preserved, or spaces where a minimal visual presence is a design priority. The fixture mounts recessed into the ceiling plane, with only the 35 mm deep housing and diffuser visible from below. Surface mounting is supported through optional brackets for soffit edges, under-cabinet surfaces, or wall-mounted applications.<\/p>\n<h2>Custom length and control options<\/h2>\n<p>Unlike fixed-length linear fixtures, the ILED-LL-A-1 can be ordered in any length between 1000 mm and 2000 mm, with bespoke cuts available for non-standard spans. This allows a single corridor, showroom aisle, or feature ceiling to be lit by one continuous run of light with no visible joints. Multiple A-1 units can be daisy-chained using DALI2 or SPI protocol, enabling synchronized control across large installations.<\/p>\n<p>The A-1 is available in five color families: single white (fixed CCT), tunable CCT (2700K\u20136500K adjustable), RGB (full colour), RGBW (colour plus white channel), and RGB+CCT (colour plus independently adjustable white). RGB and RGBW variants are controlled via DMX512 or SPI, suitable for accent lighting and architectural highlighting. White and CCT variants use DALI2 for dimming and setting, integrating into building management systems. CRI options span &gt;82 for general commercial use and &gt;92 for retail and hospitality applications where colour accuracy is critical. The 120\u00b0 beam angle provides wide, even coverage, minimizing hot spots between adjacent fixtures.<\/p>","protected":false},"excerpt":{"rendered":"<p>The ILED-LL-A-1 is a recessed linear LED fixture with an ultra-slim 35 mm profile.
