2 Metre Black Aluminium LED Corner Profile 19x19mm, Opal Diffuser

Black anodised aluminium corner profile, 19x19mm, in a 2-metre length with an opal diffuser, end caps, mounting clips and screws in the box. It bridges a 90-degree corner and takes LED strip up to 12mm wide. Against dark joinery the black body reads as a shadow line until the strip switches on; then the opal cover softens the LEDs into one even run of light with no visible fitting.

• Size: 19 x 19mm corner section, 2 metres long.
• Strip capacity: accepts LED tape up to 12mm wide.
• Build: anodised aluminium body, black finish, opal diffuser.
• IP rating: IP20 — an open channel for dry indoor rooms only.
• In the box: diffuser, end caps, mounting clips and screws.
• Guarantee: 7 years.

Where does a black corner profile work best?

Media walls, slatted panelling, charcoal kitchens, walnut wardrobes, smoked-glass shelving. A silver channel on a black panel drags the eye; this one disappears into the joinery. On slatted panels we run it along the top edge so the light rakes down the battens, invisible from standing height.

Why buy the 2-metre length?

Joins. On a 4-metre run, 2-metre lengths give you one join where 1-metre lengths give you three, and every join risks a visible break in the light line. If your run is not an exact multiple, the aluminium cuts cleanly with a fine-tooth blade — but cut the diffuser separately. Sawing the cover while it is clipped into the channel is how diffusers crack; we learned that the hard way.

The channel matters for lifespan too. Aluminium conducts heat at roughly 200 W/m·K against 0.19 for plasterboard — about a thousand times better. Heat ages LED chips, so tape in this profile runs cooler and keeps its brightness and colour for longer.

One honest caveat: an open IP20 channel waterproofs nothing inside it. If you are lighting a bathroom wet zone, a pergola or anywhere water reaches, this is not your profile — choose a sealed IP67 fitting instead.

Questions buyers ask about corner profiles

Will the aluminium body make the strip last longer?

• Yes on warm, hard-working runs — the channel pulls heat off the chips far faster than plasterboard, and heat is what shortens LED life.

Do you screw or clip a black corner profile on?

• Screw the supplied clips to the surface and snap the profile in — no adhesive to fail in summer heat, and it unclips for servicing.

How does a 2 metre profile ship, and what does it cost?

• Parcelforce 48 as a long parcel: £15.85 under £90, free at £90+; no next-day or Saturday on 2-metre lengths.

Prefer the bare-metal look? The same channel comes as a silver 19x19mm 2-metre profile. Short run? Take the 1-metre black version. For tape up to 10mm the black 16x16mm 2-metre corner profile is the slimmer pick, and the full range lives in LED strip profiles.
