Need more than 12W/m of dot-free light? Meet the SOB upgrade
COB LED strip is the reference for seamless, dot-free lines — bare flip-chip dies sit under one shared phosphor layer, and conventional COB strip is generally limited to about 12W/m. DENO's SOB (Solder-on-Board) series builds the same continuous line from individually encapsulated SMD packages, with verified builds up to 24W/m at 24V DC (25 °C ambient, aluminum profile). Spec COB for shorter, lower-load coves and joinery; consider SOB when the output target, cut unit or package protection calls for it — run length always depends on the exact model and feed layout.
