What this wire isThis is a two-conductor
18-2 low-voltage wire in a black jacket, sold and cut per foot under SKU LCWIRE-182-BK. Two conductors means one positive and one negative — everything a single-colour LED load needs. The 18 AWG conductor size is the common choice for LED lighting hookups because it carries more current than the finer signal-grade wires used for control, while staying flexible enough to tuck into an aluminum channel, a soffit cavity or the back of a cabinet. Order the footage you measured, and you get one continuous length rather than splices you did not plan for.
Why black mattersColour is not cosmetic in a lighting job — it is part of the finish. A black jacket disappears against
black LED profile, dark millwork, black soffit panels, matte black linear fixtures and dark ceiling grids. That is why so many searches pair "noir" with soffit, profile and linear fixtures: the trend toward black trims and black extrusions means white cable suddenly reads as a mistake. Using black wire on black surfaces is the difference between an installation that looks engineered and one that looks improvised. For pale ceilings, white millwork and light-coloured coves, the same wire is available in white so you can keep both colours on the truck.
Installation and handlingPlan the run before you cut. Measure from the driver or power supply to the first fixture, add slack for the loop at each end and for any turn you have to make around a joist or stud, then order that total footage. Keep the conductors identified as you work — mark one end so your polarity stays consistent all the way back to the supply, since a two-conductor black-on-black wire does not identify itself for you. Strip only as much insulation as your terminal or connector needs, avoid nicking the strands, and support the cable so it is not hanging on its own connections. For any low-voltage run, the longer the distance and the bigger the load, the more voltage drop you should account for — running the feed to the middle of a long strip and splitting it in both directions is a simple way to keep brightness even end to end.
Compatibility and companion productsUse it anywhere a single-colour low-voltage LED load needs power:
LED strip light runs and tape light in channel, under-cabinet and over-cabinet lighting, cove and tray ceilings, stair and toe-kick lighting, display cases, sign and shelf lighting, and soffit runs. It pairs naturally with the rest of the family when a job needs more conductors: the
22-4 RGB wire for colour-changing strip, the
22-5 RGB-W wire when you add a dedicated white channel, and the
FT6 22-6 standard gray wire or
FT2 22-2 standard gray wire for control and signal work. Where the cable will be visible on a light surface, the
transparent 22-2 wire is another discreet option.
Ordering and documentationThis item is priced and shipped by the foot, so quantity equals feet: enter the number of feet you need and you receive that length. There is no separate spec sheet or IES file for this product — it is a passive wiring component, not a light source — so the deciding factors are conductor count, gauge and jacket colour, all of which are stated right here. If you are still comparing, the simple rule is this: two conductors for single-colour, black jacket for dark installs, 18 AWG for the power run. Add your footage to the cart with your fixtures and connectors so everything lands on site at the same time and your crew is not waiting on wire.
