\u00bfSe pueden cortar las tiras de LED?<\/strong><\/h2>\n

Yes, many LED strip lights can be cut, but only if the strip is designed for cutting and only at the marked cut points. Disconnect power first, then look for a scissor icon, printed cut line, or copper-pad area. After cutting, reuse depends on connector fit, polarity, strip type, and product instructions, especially for waterproof, COB, RGB, smart, or addressable strips.<\/p>\n<\/section>\n

Before You Cut: Check These First<\/strong><\/h2>\n

Do not start by cutting the strip wherever the length looks convenient. LED strips are built in electrical sections, and cutting through the wrong part can leave a section unusable.<\/p>\n

Use this checklist before making the first cut.<\/p>\n

\n\n\n\n\n\n\n\n\n\n\n\n\n
Check<\/th>\nWhat to Look For<\/th>\nWhy It Matters<\/th>\n<\/tr>\n<\/thead>\n
Power disconnected<\/td>\nUnplug the strip from the power supply or controller.<\/td>\nAvoid cutting while the strip is energized.<\/td>\n<\/tr>\n
Marked cut point<\/td>\nScissor icon, dashed line, printed line, or copper-pad area.<\/td>\nThese are the intended cutting locations on cuttable strips.<\/td>\n<\/tr>\n
Strip type<\/td>\nSingle-color, RGB, RGBW, COB, waterproof, smart, or addressable.<\/td>\nDifferent strip types may need different connectors or handling.<\/td>\n<\/tr>\n
Strip width<\/td>\nCheck the physical width of the PCB.<\/td>\nSolderless connectors must match the physical strip width.<\/td>\n<\/tr>\n
Pin or channel count<\/td>\n2-pin, 3-pin, 4-pin, 5-pin, or another pad layout.<\/td>\nMulti-color strips need connectors with matching channels.<\/td>\n<\/tr>\n
Polarity marks<\/td>\n\u201c+\u201d, \u201c-\u201d, voltage labels, or channel labels.<\/td>\nReversed polarity or misaligned channels can stop the strip from working.<\/td>\n<\/tr>\n
Coating or waterproof sleeve<\/td>\nSilicone coating, tube, or sealed outer layer.<\/td>\nCutting may require resealing or special connector handling.<\/td>\n<\/tr>\n
Product manual<\/td>\nEspecially for smart, RGBIC, addressable, or waterproof strips.<\/td>\nSome cutting limits are not obvious from appearance.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

If the strip has no visible cut marks and no product instructions confirming it is cuttable, do not assume it can be cut.<\/p>\n

Where to Cut LED Strip Lights<\/strong><\/h2>\n

Cut only at the designated cut point. On many LED strips, this appears as one of the following:<\/p>\n
