The HELIAN HL-A002 ceiling-corner profile was specified because it accepts a max 13 mm wide LED strip on its main face and a max 7 mm wide strip on its inner corner, allowing the same profile to wash the wall side and the ceiling side at independent brightness.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">User Pain Points and Needs<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Need 1 \u2014 Two-direction wash from one channel.<\/strong> The design called for asymmetric brightness on wall vs ceiling from a single fixture line in the corner.<\/li>\n\n\n\n<li><strong>Need 2 \u2014 Continuous, gap-free corner runs.<\/strong> Retail walls of up to 8 m required single-piece lines through 90\u00b0 ceiling corners without mid-span joints.<\/li>\n\n\n\n<li><strong>Need 3 \u2014 Concealed corner installation.<\/strong> The profile had to disappear into the drywall corner with only the diffuser face visible.<\/li>\n\n\n\n<li><strong>Need 4 \u2014 One supplier for profile and optics.<\/strong> PC and PMMA diffusers had to come from the same manufacturer as the profile body.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Solution<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">HELIAN supplied the <strong>HL-A002<\/strong> profile from its A-Series:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Body:<\/strong> AL 6063 aluminium with anodised or painted silver surface.<\/li>\n\n\n\n<li><strong>Lighting source width:<\/strong> max 13 mm \/ max 7 mm (asymmetric dual-channel).<\/li>\n\n\n\n<li><strong>Cover (PC \/ PMMA push-in):<\/strong> PC; Cover Model BAPL001 \/ BAPL02S.<\/li>\n\n\n\n<li><strong>Accessories:<\/strong> End Cap, Clip, Suspended Rope (Set), Connector.<\/li>\n\n\n\n<li><strong>Length:<\/strong> 4 m

class=\"wp-block-list\">\n<li><strong>Asymmetric corner wash.<\/strong> The 13 mm and 7 mm channels delivered independently dimmed wall and ceiling illumination from a single corner fixture.<\/li>\n\n\n\n<li><strong>8 m single runs.<\/strong> Per-side runs up to 8 m were supplied in 4 m stock lengths and joined cleanly at the corner.<\/li>\n\n\n\n<li><strong>Concealed profile.<\/strong> Only the diffuser face is visible; the aluminium body hides fully in the drywall corner.<\/li>\n\n\n\n<li><strong>Fire \/ smoke compliance.<\/strong> PC cover across the entire scheme satisfied the building code with a single material declaration.<\/li>\n\n\n\n<li><strong>Quantified outcome.<\/strong> 320 m of HL-A002 installed across retail, fitting rooms and corridor; the dual-channel scheme cut fixture count by 33% vs the originally specified separate wall and ceiling strips.<\/li>\n<\/ul>\n\n\n<style>.wp-block-kadence-advancedheading.kt-adv-heading22636_6bfcd4-91,
