Special Dimensions
LED panels offer energy-efficient and uniform light distribution, making them widely used in offices, schools, shops, and other commercial spaces. Although most LED panels follow the standard dimensions of 60x60 cm for suspended ceilings, there are specific situations and regions where non-standard sizes are required. It is important to choose the correct dimension to ensure the panel fits seamlessly into the ceiling grid.

Non-Standard LED Panel Dimensions: Focus on German Sizing
The most common standard dimensions for LED panels are 600x600 mm and 1200x300 mm. However, particularly in Germany and Austria, a grid size of 625x625 mm is often used for suspended ceilings. This is a crucial detail when selecting LED panels for projects in these regions or in buildings with a similar ceiling structure. Choosing the wrong size can lead to unnecessary modifications and extra costs.
| Dimension (mm) | Explanation | Typical Application |
|---|---|---|
| 600x600 | International standard size | Office buildings, shops, schools |
| 625x625 | Common non-standard size, prevalent in Germany and Austria | Projects in German-speaking countries, older buildings |
| 1200x300 | International standard size for longer spaces | Corridors, aisles, open-plan offices |
| 1250x312 | Derived dimension for specific ceiling grids | Specific renovation projects |
| 1200x600 | Larger format for higher light output | Warehouses, large commercial spaces |
| 300x300 | Smaller, flexible dimension | Toilets, small spaces, accent lighting |
Why the Correct Dimension is Important
Installing LED panels in a suspended ceiling requires precise dimensions. A 600x600 mm panel will not fit correctly in a 625x625 mm grid, and vice versa. This 2.5 cm difference may seem small, but it causes problems with installation and aesthetics. Moreover, a well-fitting panel guarantees a safe installation and a sleek, uniform appearance of the ceiling.
For projects with a non-standard ceiling size, such as the 625x625 mm version, it is advisable to specifically look for panels designed for this purpose. This prevents unnecessary costs for custom work or adjustments to the ceiling grid.
Considerations When Choosing Special LED Panels
Besides the dimensions, other technical specifications play a role in selecting LED panels with special sizing:
- Luminous Flux (Lumen): Ensure that the brightness (expressed in Lumen) of the panel is sufficient for the specific room and activity. Large spaces or areas with detailed work require a higher light output.
- Colour Temperature (Kelvin): The light colour, measured in Kelvin, affects the atmosphere. Warm white (around 3000K) creates a pleasant ambiance, while cool white (4000K or more) is more functional for workplaces.
- Colour Rendering Index (CRI): A high CRI (minimum of 80) indicates that colours are rendered accurately. This is relevant in environments where colour recognition is important, such as in shops or studios.
- UGR Value (Glare Rating): A low UGR value (e.g., <19) indicates that the panel causes little glare, which is important in offices or for screen work.
- Dimmable Options: If flexibility in light intensity is desired, dimmable LED panels are a consideration. Check compatibility with the dimming system.
- Mounting Accessories: In addition to being recessed into a suspended ceiling, there are often surface-mounted frames or suspension kits available to mount the panels in other ways, for example, on a fixed ceiling or as a pendant fixture. [Link to page about mounting accessories]
Frequently Asked Questions about Special Sized LED Panels
Are LED panels with non-standard sizes more expensive?
Generally, panels with non-standard dimensions, such as 625x625 mm, can be slightly more expensive than the standard 600x600 mm versions due to lower production volumes. However, the additional cost is usually minimal and outweighs the cost and effort of modifying the ceiling.
Are there also round LED panels with special sizes?
Besides square and rectangular panels, round LED panels are also available, often in various diameters. These are typically not classified based on a specific ceiling grid but rather used as decorative or accent lighting. Some suppliers even offer custom-cut panels in non-standard round or other shapes. [Reference to a blog article about custom-made LED panels or a product page with round panels]
Can I install a 600x600 mm LED panel in a 625x625 mm ceiling?
No, this is not recommended. A 600x600 mm panel will be too small for a 625x625 mm grid, leaving a gap. This not only looks unfinished but can also lead to issues with stability and light leakage. Always choose the exact size that matches the ceiling grid.
