non-addressable is simpler (dimming, static scenes) with fewer compatibility risks.<\/li>\n<li><strong>Addressable COB vs SMD pixel strips:<\/strong> COB tends to look more like a continuous line; SMD pixel strips can be more serviceable\/visually \u201cpixel-like\u201d depending on diffuser and pitch.<\/li>\n<\/ul>\n<h3>Boundary conditions<\/h3>\n<ul>\n<li>COB form factor does <strong>not<\/strong> define voltage, wattage, brightness, or max run length\u2014those are model-specific and must be verified by datasheet.<\/li>\n<li>Addressability can be per-segment; segment size affects how smooth effects will look.<\/li>\n<li>The \u201cdotless\u201d look depends on density and your channel\/diffuser design, not addressability alone.<\/li>\n<\/ul>\n<h3>Segment Addressable vs Per-Pixel: How to Set Effects Expectations<\/h3>\n<p>\u201cSegment addressable\u201d means the strip is controlled in zones (segments) where each segment changes together\u2014so effects are possible, but not necessarily at single-LED resolution.<\/p>\n<ul>\n<li><strong>Segment size controls effect smoothness:<\/strong> smaller segments can look smoother for chases\/gradients; larger segments look more \u201cstepped.\u201d<\/li>\n<li><strong>Grouping affects system complexity:<\/strong> more segments typically increases mapping\/config effort, especially when bridging into DMX workflows.<\/li>\n<li><strong>Procurement tip:<\/strong> ask for \u201csegment length \/ pixel grouping\u201d and \u201chow it\u2019s represented to the controller\u201d in the datasheet or wiring notes.<\/li>\n<\/ul>\n<p><strong>Boundary conditions:<\/strong> Grouping is model-dependent;
