GLOW12 DOWN A1C
GLOW12 DOWN – Aluminium LED Profile for Indirect Wall Lighting
GLOW12 DOWN A1C by TOPMET Light is an architectural aluminium LED profile designed for installation along the edges of suspended plasterboard ceilings. It creates a soft, downward-directed glow on the upper section of the adjacent wall, adding depth and a subtle decorative lighting effect to interior spaces.
Compatible with LED strips up to 12 mm wide, GLOW12 DOWN combines indirect lighting with a practical solution for finishing plasterboard ceiling edges.
Subtle Wall Illumination and Clean Ceiling Edges
The GLOW12 DOWN plaster-in LED profile is designed for use with standard 12.5 mm plasterboard. Its mounting flange is fixed to the board, allowing the attachment area to be filled and painted for a neat, integrated finish.
The visible section of the profile covers the exposed plasterboard edge, reducing the need for additional finishing elements.
By directing light towards the wall, GLOW12 DOWN highlights architectural details and creates a gentle ambient effect. It is particularly suitable for residential interiors, hotels, reception areas and other spaces where discreet decorative lighting is desired.
Compatible Diffusers and Accessories
GLOW12 DOWN supports two system diffuser types:
- A1 slide-in diffuser – available in transparent, frosted and opal versions.
C click-in diffuser – available in transparent, opal and black versions.
The C opal diffuser is also available in a 20-metre roll, helping reduce visible joints in longer lighting installations.
An integrated Slick groove allows the A1 slide-in diffuser to be clicked into place, simplifying installation and subsequent maintenance.
GLOW12 DOWN is compatible with dedicated GLOW12 end caps, shared with the GLOW12 UP profile.
The profile is available in raw aluminium and anodised finishes, with lengths of 1000, 2000, 3000 and 4050 mm.
Combining indirect wall illumination, integrated plasterboard edge finishing and compatibility with system diffusers, GLOW12 DOWN aluminium LED profile provides a practical solution for contemporary architectural lighting.
