Two distinct modes: (a) flexible COB / SMD tape up to 4.7 mm wide for the standard PC diffuser (Clear / Frosted / Opal); (b) CSP1208 rigid LED strip, 100 mm length, 14 beads per segment, for the reflector-cup / lens / black-cover options. The two modes cannot be mixed on the same cup — flexible strip does not fit the cup/lens/cover accessories.

Any 90° inside corner. The two 9 mm legs of the wedge fit against the two perpendicular surfaces — typically wall/ceiling, wall/wall, stair-tread/stair-riser, or cabinet soffit/wall. Both legs are screwed directly to their respective surface (wood, plywood, MDF, plasterboard, metal framing, or thin stone with appropriate anchors). No routing or slot is required, and the two surfaces do not need to be flush with each other — each leg is screwed to its own surface and the 12.6 mm diagonal face bridges the corner. The 45° beam fires straight outward from the corner, making the YD-2570 ideal for ceiling cove uplight, under-cabinet indirect, and corner accent lighting — applications where you want the fixture hidden in the corner and the light to read as a diagonal wash straight into the room.

YD-2565 is the entry-level mini profile — 7 × 8 mm, surface mounting or magnetic mounting, fastest install. YD-2566 is the recessed variant of YD-2565 — same 7 × 8 mm body but with a 9 mm top flange, designed to drop into a routed slot for a fully flush look (straight down beam, no baffle). YD-2567 is the wall-grazing surface-mount option — 9 × 9 mm square body with a 30° angled internal channel; the profile hangs below the mounting surface, held by metal clips. YD-2568 is the recessed wall-grazing option for ceilings and coves — 9 × 8 mm body with an 11 mm bottom flange, designed to drop into a routed slot for a fully flush look with the 30° angled beam washing the upper wall. YD-2569 is the recessed shelf-light option with anti-glare baffle — 9 × 8 mm body with an 11 mm flange and a 13 mm baffle that mechanically hides the LED ('see light, not see the lamp'), designed for under-shelf, in-step or in-cove installation where the LED must be shielded from direct view. YD-2570 is the 45° corner-mount option — 9 × 9 mm 45° right-angle wedge with a 12.6 mm hypotenuse; the 4.8 mm LED channel sits parallel to the diagonal face so the beam exits at 45° straight outward from any 90° inside corner — the two 9 mm legs are screwed to the surfaces, no routing. YD-2575 is the larger advanced option — 8.6 × 7.3 mm with three mounting modes (surface / wall-lamp / 180° adjustable rotation). All seven share the same triple optical configuration (PC diffuser / reflector cup + lens / reflector cup + black cover) and 100 mm modular accessories.

The 4.8 mm internal LED channel sits parallel to the 12.6 mm hypotenuse, so the beam exits perpendicular to the diagonal face — i.e. straight outward from the corner at 45° from horizontal. Unlike the 30° asymmetric wall-grazing geometry of YD-2567 / YD-2568 / YD-2569, this is a symmetric straight-out beam — neither biased toward one surface nor the other. Install the YD-2570 at the inside corner where a wall meets the ceiling (or where two walls meet, or stair tread meets riser), and the beam fires diagonally outward into the room — perfect for ceiling cove uplight, under-cabinet indirect wash, and corner accent lighting. Because YD-2570 is surface corner-mounted, the 12.6 mm diagonal face is the only visible part of the profile; the two 9 mm legs disappear into the corner.

Cut to any length; standard tolerance ±0.5 mm. Tighter tolerances available on request.

Two end caps (one with cable hole for power feed-through, one closed) per metre of profile. Optional metal mounting clips (with screw holes) are supplied on request — recommended for ceiling installations and any application where vibration or accidental contact might displace the profile. The reflector cup, lens and black cover are quoted separately, priced per 100 mm module — same SKUs as YD-2565, YD-2566, YD-2567, YD-2568, YD-2569 and YD-2575.
