{"product_id":"12v-4-8w-led-strip-light-5m-4000k-cool-white","title":"12V 4.8W LED Strip Light 5m - 4000K Cool White","description":"\u003ch5\u003eDescription\u003c\/h5\u003e\n\u003cp\u003eThe Knightsbridge LFX512CW is a 5-metre roll of 12V LED strip light delivering 535 lumens per metre at 4000K cool white. Each metre carries 60 x 2835 SMD LEDs spaced along an 8mm-wide flexible circuit board, consuming 4.8W per metre with a combined output of 115.1 lumens per watt. The strip runs on 12V DC constant voltage and arrives with 3M self-adhesive backing already applied to the rear of the PCB.\u003c\/p\u003e\n\u003cp\u003eDesigned for under-cabinet lighting, shelving accent, cove lighting and signage, the strip can be cut at marked intervals to fit specific installation lengths. The 4000K colour temperature sits between warm white and daylight, providing neutral illumination suited to kitchens, offices, retail displays and workshops where colour rendering matters but warmth is not a priority. The IP20 rating limits use to dry indoor locations away from moisture and dust ingress.\u003c\/p\u003e\n\u003cp\u003eThe strip requires a separate 12V constant voltage LED driver sized to the total wattage of the installation — a full 5m roll draws 24W, so a driver rated 30W or higher is recommended to allow headroom. Dimming capability depends on the driver model selected; pairing with a dimmable driver and compatible wall control enables full 0-100% dimming. The 120-degree beam angle from the SMD LEDs provides even spread along the length of the strip without visible hot-spotting when mounted inside aluminium channels or behind diffusers.\u003c\/p\u003e\n\u003cp\u003eThe 3M adhesive backing bonds to clean, dry surfaces including painted metal, sealed wood, glass and most plastics. For permanent installations or surfaces where adhesive may fail over time, supplementary mechanical fixing with aluminium channels or cable clips is recommended. The strip's 1.2mm thickness and flexibility allow it to bend around gentle curves and corners, though tight radius bends can damage the circuit traces. Knightsbridge provides a 3-year warranty and the LEDs are rated to L70B50 at 54,000 hours — the point at which 50% of LEDs will have degraded to 70% of initial output.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e5300 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e1.2 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003eIII\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e12V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Length\u003c\/td\u003e\n\u003ctd\u003e0.3 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Technology\u003c\/td\u003e\n\u003ctd\u003eLED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Included\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eDriver dependent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eL70B50\u003c\/td\u003e\n\u003ctd\u003e54000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating (Class) post 2021 SLR\u003c\/td\u003e\n\u003ctd\u003eF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCCT\u003c\/td\u003e\n\u003ctd\u003e4000 K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Colour\u003c\/td\u003e\n\u003ctd\u003eCool White\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens\u003c\/td\u003e\n\u003ctd\u003e535 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e4.8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficacy\u003c\/td\u003e\n\u003ctd\u003e115.1 lm\/W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCRI\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_4018501_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_1111328.pdf\" target=\"_self\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eCan the strip be cut to a specific length?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
