Decking LED Lights White 6x12mm IP67 24V 1cm cut 15m

For decking projects where every centimetre matters. Our 6x12mm IP67 LED Neon Flex with 1cm cut points is built for narrow boards under 200mm, stair nosings, riser edges, and detail trim work where 5cm precision falls short. Cut at any 10mm mark, recess into the channel, power up — your light line matches the timber to the millimetre.

Continuous run of 15 metres from one feed, 30 metres with dual-end power. 24V DC, 120 LEDs per metre, IP67 silicone construction rated for permanent UK outdoor use across -30°C to 50°C. The 120° beam casts an even, dot-free wash with no visible LED hotspots — critical when the flex sits inches from foot traffic on a deck.

Where 1cm precision earns its place

Stair nosings and riser detail: deck stairs typically have 17-20cm rises and 25-30cm treads. The 1cm cut interval means you can match every nose, every riser, every tread edge without offcut waste. The 6x12mm profile sits flush in standard riser channels.

Narrow timber boards: hardwood decking boards in 90mm and 120mm widths leave no room for a 5cm cut error. Cut at 1cm intervals to fit board-by-board across mixed widths.

Tight perimeter detail: patio borders that turn corners every 1-2 metres, raised planter capstones, irregular bay windows, alcove trim — anywhere the run breaks frequently.

Garden steps and short paths: garden steps under 60cm wide, herb-bed borders, shallow water-feature surrounds. Most domestic step schemes need 10-15m total — exactly what this reel covers.

Install detail for a tight fit

Cut tolerance: the laser-etched 10mm marks define where the internal circuit can safely break. Cutting between marks shorts the segment and voids the IP67 seal. If you must cut between marks, our team will reseal end-caps before dispatch.

Driver sizing for a 15m run: 15m × 9W/m = 135W. With the 1.2 safety multiplier you need a 165W minimum — round up to a 200W 24V driver. Smaller and the driver overheats inside the first summer.

Bend radius — 1.5cm horizontal: tighter than that and the LED chips inside the silicone fracture. Vertical bending is not supported on this profile.

Profile recommendation: our slim 6x12mm aluminium decking channel sits flush with the board surface. The channel doubles as a heatsink — important on stair nosings where heat builds up against timber.

BS7671 compliance: low-voltage installation must use a properly isolated DC driver, not direct mains. Competent installer required for permanent installations.

For compact UK home gardens and courtyard patios

UK homeowners with smaller outdoor spaces get full coverage from a single 15m reel. Typical residential installs at this scale:

Courtyard and mews terraces: city homes with side returns, walled courtyards, and enclosed terraces under 15m total perimeter. The 1cm cut handles the irregular geometry of older brick and limestone courtyards.

House-to-lawn step lighting: short flights of 3-5 garden steps connecting the house door to a sunken lawn or lower patio level. Each tread illuminated separately, no offcut waste.

Kitchen herb beds and raised planters: small raised herb gardens and planter walls under 1.2m high. The 6x12mm slim profile sits flush in the planter capstone groove.

Wildlife pond surrounds: small ornamental ponds and rills under 4m diameter — frequent direction changes around the water feature edge.

Choose your colour temperature

2700K warm white — deep amber tone, used most often on timber decking where warmth complements the wood grain.

3000K warm white — soft warm white, the popular default for residential UK decking. Pairs with cedar, oak, and warm-toned composite boards.

4000K natural white — neutral, modern. Recommended for grey composite decking and contemporary garden builds.

6000K cool white — daylight crisp. Used for security-led step lighting and commercial premises where visibility trumps mood.

Need a longer run or different cut?

Decking LED Lights 24V — 5cm cut, 20m: longer single-feed run, slightly less cut precision. Choose this for typical decking projects over 15m.

Decking LED Lights 48V — 10cm cut, 40m: the long-run option. 48V halves voltage drop. Pick this for decking projects past 20m.

Custom-cut to your exact length before dispatch. Tell us the metre count, we cut, seal the IP67 end, and ship.
