18×16mm Flat 48V LED Neon Flex 4000K IP68 – 50m Roll

Form a clean natural-white feature line with this 4000K, flat-face LED Neon Flex. Its 48V format and 50 metre supplied roll suit planned architectural outlines, garden features and display work, while the PVC body measures 18mm wide × 16mm high.

Measure around 10cm increments

Cut marks are spaced at 100mm (10cm). The body is top/vertical bend, so it can arc in that plane only; side bending, twisting and kinking can damage it. Set out the route and feed positions before cutting.

Key specifications

• Natural white light: 4000K
• 48V DC input; 11W/m
• IP68 PVC Neon Flex
• 18mm W × 16mm H flat profile
• Top/vertical bending direction
• 100mm (10cm) cutting interval
• One 50m roll
• 30m maximum continuous run from one end

Do not power all 50m from one end

Plan additional, correctly rated feeds for any installation longer than the stated 30m run. Use a compatible 48V constant-voltage power supply, unroll the flex before power-up and seal every cut, end, join and cable entry using compatible methods. IP68 for the product body is not a blanket rating for unfinished connections, and the source supplies no underwater test parameters. The light is fixed 4000K white, not colour-changing.

Made-to-measure help is available from UK LED Lights via Custom Projects. Bespoke sections must follow the 10cm cut marks and 30m electrical limit.
