GLOW12 UP A1C
GLOW12 UP – Aluminium LED Profile for Indirect Ceiling Lighting
GLOW12 UP A1C by TOPMET Light is an architectural aluminium LED profile designed for installation along the edges of suspended plasterboard ceilings. It directs light upwards towards the main ceiling, creating a soft, diffused glow that adds depth and atmosphere to interior spaces.
Compatible with LED strips up to 12 mm wide, GLOW12 UP combines decorative indirect lighting with a practical solution for finishing plasterboard ceiling edges.
Soft Uplighting and Integrated Ceiling Finishing
The GLOW12 UP plaster-in LED profile is designed for use with standard 12.5 mm plasterboard. Its mounting flange is attached to the board, allowing the fixing area to be filled and painted for a clean, integrated appearance.
The visible section of the profile provides a neat finish to the exposed plasterboard edge, eliminating the need for separate finishing trims.
Unlike GLOW12 DOWN, which directs light towards the wall, GLOW12 UP illuminates the main ceiling above the suspended structure. This creates a subtle ambient lighting effect, particularly suitable for living spaces, hotels, reception areas and contemporary commercial interiors.
Compatible Diffusers and Accessories
GLOW12 UP 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 minimise 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 UP is compatible with dedicated GLOW12 end caps, shared with the GLOW12 DOWN profile.
The profile is available in raw aluminium, anodised and white painted RAL 9003 finishes, with lengths of 1000, 2000, 3000 and 4050 mm.
Combining indirect ceiling illumination, integrated plasterboard edge finishing and compatibility with system diffusers, GLOW12 UP aluminium LED profile provides a functional solution for modern architectural lighting.
