Description
2835 Dual Loop LED Strip 240LEDs/m | 10mm | 24V | 240LEDs | 50mm/cut | #19291 Designed with an independent dual-loop architecture, this product allows for separate circuit control and versatile functional switching. By utilizing a shared substrate and integrated protective structure, it eliminates the need for redundant strip installations, significantly optimizing space and reducing both material and labor costs. The system features robust fault tolerance, where a backup circuit ensures continuous illumination even if one loop fails. Furthermore, it supports luminous flux superposition with manageable power consumption; when both channels are active, the combined output delivers high-intensity lighting suitable for demanding professional applications.
Special Application Led Strip built for special smd strips projects.

Frequently Asked Questions
What are the key specifications of 19291?
19291: 2835, 240, DC 24V, 10mm PCB, 3oz copper FPCB, cuttable 12LEDs/50mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.
Which environments is this special application LED strip rated for?
Ingress protection for this model is listed in the datasheet. As a special application LED strip it is specified for the duty listed in the datasheet, and DENO can supply alternative coatings, sleeves or IP68 potting for harsher installations.
Can DENO customise this special application LED strip for a project?
Yes. DENO manufactures the Special SMD Strips series as an OEM and ODM supplier: reel length, colour temperature, CRI grade, PCB width, waterproofing and private labelling can all be specified. Request a quote for lead time and project pricing.
What can be customised on an OEM LED strip order?
FPCB width and copper weight, LED type and density, CCT and CRI bin, cut interval, reel length, connector and encapsulation can all be specified. As a direct LED strip manufacturer, DENO builds to drawing, including non-standard shapes and project-specific labelling.
