Arum Curve Cove Lighting Profile — Detailed Review
An honest review of the Arum Curve cove molding profile — specs, standout features, ideal use cases, and a full cost breakdown for a typical 10-meter living room installation.

The Arum Curve is the most popular cove lighting profile in Arumstores’ lineup, designed to reflect LED light off the ceiling in a continuous, softly curved arc. This review covers everything from actual performance to pricing and which projects it suits best.
What Is It?
Arum Curve is a cove lighting profile (also called a cove molding or LED channel) made from high-quality PU (polyurethane). Its distinctive curved shape is engineered to scatter LED light upward and reflect it off the ceiling as a smooth, seamless glow — with no visible source and no harsh hot spots.
PU has notable advantages over traditional materials: it resists moisture, doesn’t warp, can be painted any color, and flexes slightly with building movement instead of cracking like gypsum.

Standout Features
1. Smooth curved light reflection The curved geometry means light diffuses outward in a graceful arc — noticeably softer and more premium-looking than a flat-sided profile.
2. Fully conceals LED strip and wiring The deep channel accommodates a 10mm COB strip plus connection wiring, completely hidden from view.
3. PU resists moisture and warping Suitable for kitchens and spaces near bathrooms without the warping or cracking that gypsum is prone to.
4. Paintable surface Match the Arum Curve to any ceiling color with standard interior paint.
5. Easier to install than gypsum Silicone + screws is all you need — no specialist plastering skills required.
6. Handles building movement PU flexes slightly as buildings settle or expand with temperature. Gypsum cracks; PU doesn’t.
Best Applications
Ideal for:
- Modern / minimalist living rooms — the curved line complements contemporary interior styles
- Premium bedrooms — soft evening light ideal for winding down
- Hotel rooms and guesthouses — elevates the room feel at a relatively low cost
- Hallways and entryways — creates a seamless light path
- Buildings that are still settling — older buildings or wooden-framed homes where cracking is a concern
Not ideal for:
- Ceilings lower than 2.3m — the 60mm height will feel oppressive; use the thinner Arum Edge profile instead
- Extremely tight budgets — PU is more expensive than foam alternatives
