Panel Sizes Explained (600x600, 1200x600 and 1200x300)

600x600mm is the most popular choice because it matches the standard suspended ceiling grid used in offices and schools. The actual physical size of the LED panel is 595x595mm, but its classed as 600x600m as it fits in this size of ceiling grid.

1200x600mm panels cover the equivalent of two 600x600 tiles. They’re common in larger open-plan areas where you want fewer fittings, faster installation and a cleaner ceiling layout. The actual size of the panel is 1295x595mm.

1200x300mm is a slimmer format often used in corridors, narrow ceiling grids, reception walkways, or where the ceiling layout doesn’t suit square modules. The size of the LED panel is 1195x295mm.

Colour Temperature: What Most People Actually Choose

For commercial interiors, 4000K (cool/neutral white) is the most common choice. It looks clean, supports concentration, and works well with modern office finishes. Its white but not too harsh.

• 3000K warm white: better for hospitality-style areas, reception, breakout spaces and softer interiors
• 5000K / 5700K daylight: crisper and more “daylight-like”, sometimes used for task-heavy areas
• CCT switchable: one panel with multiple colour temperatures (useful when you’re unsure what the client will prefer)

If you want flexibility on site, consider a CCT option such as: Aurora Multi-Wattage 18-26W CCT Backlit LED Ceiling Panel (shown above) or the Ovia 600x600mm CCT & Wattage Switchable LED Panel.

Lumens and Wattage: Don’t Choose on Watts Alone

Panel wattage is useful for comparing energy consumption, but lumens (lm) determine how bright the space will feel. Many modern panels also offer wattage switching, so you can select the appropriate output during installation (helpful if a room ends up feeling over-lit or under-lit). LED panels range from 1750 lumens to 4620 lumens for a high output version.

A good example of a flexible, installer-friendly option is: JCC Skytile 600x600mm LED Ceiling Panels UGR19 which is available in a choice of wattage outputs and includes a loop-in, loop-out wiring connector.

UGR Rating for Offices: Does It Have to Be UGR19 or Lower?

UGR is used to manage discomfort glare in commercial spaces, especially where people work under the lighting for long periods or use screens. In practice, UGR<19 is the standard target for offices and classrooms because it balances visual comfort with cost and availability.

Is it a legal requirement? It depends on the specification and the project requirements, rather than a universal “law” for every building. However, many office and education projects are designed to recognised workplace lighting guidance, where UGR19 is widely treated as the compliance benchmark for typical work areas.

If you want enhanced glare control (executive offices, design studios, premium fit-outs), consider UGR16 options such as: Ovia 600x600mm UGR16 Ultra Low-Glare LED Panel.

Backlit vs Edge Lit

LED ceiling panels are commonly available in two designs: edge-lit and backlit. Edge-lit panels place the LEDs around the frame and direct light across a light guide plate, allowing for a slimmer profile and lower cost, making them popular for basic office and retrofit applications. Backlit panels position the LEDs directly behind the diffuser, delivering more even light distribution, higher lumen output and improved long-term reliability. As a result, backlit panels are now the preferred choice for many commercial projects, particularly where consistent brightness, reduced shadowing and better performance over time are required.

TP(a) vs TP(b): What Does It Mean?

TP(a) and TP(b) refer to the fire performance classification of the diffuser material used in LED ceiling panels when installed as part of a suspended ceiling. TP(a) panels use a diffuser that meets stricter fire propagation requirements, making them suitable for use where the panel effectively forms part of the ceiling construction. Because of this, TP(a) is commonly specified in offices, schools, healthcare buildings and other commercial environments.

TP(b) panels use a diffuser with a lower fire performance rating and are typically limited to applications where the panel is not relied upon as part of the ceiling’s fire integrity, or where regulations are less stringent. In practice, most modern commercial projects specify TP(a) as standard, and TP(b) is increasingly uncommon outside of basic or legacy installations.

What Is the Recommended Lux Level for an Office?

For general office work, a maintained illuminance level of around 500 lux at desk height is widely recommended. This level provides comfortable visibility for screen use, reading and writing without causing unnecessary glare or eye strain. Areas such as meeting rooms, classrooms and open-plan offices typically work well at this level, while lower levels (around 300 lux) may be acceptable in circulation areas such as corridors, and higher levels may be required for detailed or precision tasks.

Applications: Where Each Panel Type Works Best

• Offices & meeting rooms: 600x600, 4000K, UGR<19, optional DALI/1–10V controls
• Schools & classrooms: UGR<19 as a baseline, with UGR16 for higher comfort / longer occupancy
• Corridors & circulation: 1200x300 is common; glare control still matters but tasks are less demanding
• Washrooms / kitchens / canteens: look for IP44–IP54 depending on moisture and cleaning

IP Rating: IP20 vs IP65 (What You Actually Need)

IP20 panels are suitable for general indoor areas (offices, classrooms, meeting rooms). If the panel is exposed to moisture, steam, splashes or regular cleaning, step up to IP44 or IP65. For higher moisture environments, IP-rated panels reduce the risk of ingress and premature failure.

Examples include:
Aurora IP54 600x600 LED Backlit Ceiling Panel and Aurora IP54 1200x600 LED Backlit Ceiling Panel.

Dimming and Controls: Why DALI and 1–10V Are Common

Many LED panels are supplied as non-dimmable, which is fine for standard “on/off” installations. Where dimming is required in commercial settings, it’s more common to use 1–10V or DALI control rather than mains (TRIAC) dimming. Mains dimming is less typical in commercial projects due to higher circuit loads, compatibility constraints and the need for centralised control strategies.

Surface Mounting Frames

If you don’t have a suspended grid ceiling, a surface mounting frame lets you install a panel onto a solid ceiling. Suspension kits can also be used where you want a “floating panel” look or need to drop below services. Most lighting brands have a wide range of mounting accessories available.

Best Value LED Panels

Ultimately, price often plays an important role in purchasing decisions, particularly on large projects where multiple panels are being installed. Some applications simply need to meet basic performance and compliance requirements without unnecessary features, making value-led LED panels a sensible choice.

Best-value panels typically focus on the core essentials: standard sizes (most commonly 600x600mm), a fixed colour temperature such as 4000K, reliable lumen output, a UGR might not be required, or a higher glare rating such as UGR22 might be possible to use. By avoiding premium optics, advanced control gear or ultra-low glare designs, these panels offer a cost-effective way for new projects or to upgrade or replace existing fluorescent ceiling grids.

We have price beating panels available at around the £10 mark which can be viewed in order of price. Higher specification panels with UGR19 compliance are around £20 each.

Reliability and Warranty

Reliability is a key consideration in commercial lighting, particularly where access for maintenance is limited or disruptive. Many LED ceiling panels are supplied with return-to-base warranties, but some manufacturers go further. Aurora Lighting offers a 3-year on-site warranty and 5 year standard on selected LED panel ranges such as the Aurora BackLite 600x600mm LED Backlit Ceiling Panels, meaning any approved fault is dealt with at the installation location rather than requiring removal and return. This reduces downtime, avoids disruption to occupied spaces, and provides additional peace of mind for facilities managers and contractors responsible for long-term performance.

General Q&A

What size LED ceiling panel do I need for an office?

Most offices use 600x600mm LED ceiling panels because they fit standard suspended ceiling grids. Larger spaces may use 1200x600mm panels to reduce the number of fittings, while 1200x300mm panels are often used in corridors or narrow ceiling layouts.

Do LED panels have to be UGR19 or lower in offices?

UGR19 is widely treated as the standard target for office and classroom lighting because it provides an appropriate level of glare control for screen-based work. While it is not a universal legal requirement, many office lighting specifications are designed around UGR<19 to meet workplace guidance and visual comfort expectations.

What colour temperature is best for office LED panels?

4000K cool white is the most popular choice for offices as it provides a clean, neutral light that supports concentration. Warmer 3000K is sometimes used in reception or breakout areas, while 5000K or daylight options are used where a brighter, more clinical feel is required.

Are LED ceiling panels dimmable?

Most standard LED panels are supplied as non-dimmable. Where dimming is required in commercial environments, panels are typically controlled using 1–10V or DALI systems rather than mains (TRIAC) dimming, which is less common due to higher power loads and control limitations.

What does TP(a) mean on an LED panel?

TP(a) refers to the fire performance classification of the panel diffuser when installed as part of a suspended ceiling. TP(a) panels meet stricter fire propagation requirements and are commonly specified for offices, schools and commercial buildings.

Can LED ceiling panels be surface mounted?

Yes. If you don’t have a suspended ceiling, LED panels can be installed using surface mounting frames or suspension kits, allowing them to be fitted onto solid ceilings while maintaining a clean, professional appearance.
