SkyLume TR -- Sun Simulation Round
SkyLume TR -- Sun Simulation Round
The Most Realistic Artificial Sun.
Round sun simulation panel combining high-intensity solar disc projection with full-spectrum Rayleigh scattering optics -- 500-600W, 20,000+ lumens, tunable 2,100K-7,800K CCT in a circular porthole design.
The Concept
The SkyLume TR is the most realistic artificial sun ever built. Combining the circular porthole aesthetic of the ER series with the high-intensity sun simulation technology of the T series, the TR projects a defined solar disc through a round aperture -- the closest engineering has come to placing a real sun behind your ceiling.
Unlike the T-series square panels which operate at a fixed 6,500K, the TR features full CCT tunability from 2,100K warm amber through 7,800K cool daylight blue. This means the TR can simulate not just a midday sun, but a sunrise, a golden hour, a cloudy overcast, or a clear blue noon -- all from the same circular fixture. The combination of sun disc projection and full spectrum control makes the TR the ultimate circadian lighting instrument.
Available in TR300 (600mm diameter) and TR600 (900mm diameter), both models deliver 500-600W of concentrated solar output exceeding 20,000 lumens. The TR300 at 380mm deep houses the complete optical assembly including the Rayleigh scattering diffusion layer, the sun disc projection module, and the full-spectrum LED array. Control via BLE Mesh 5.0, DALI, and 0-10V enables seamless integration with building management systems.
Key Features
- Most Realistic Artificial Sun -- Round form factor with visible sun disc and surrounding blue sky creates the most convincing overhead sun simulation available in any artificial skylight.
- Tunable CCT (2,100K--7,800K) -- Unlike the T-square (fixed 6,500K), the TR offers full spectrum tunability for circadian scheduling, mood lighting, and dynamic sky simulation.
- >20,000 Lumens -- Extraordinary luminous output from the TR300; the TR600 exceeds this further. Genuine sunlight-level brightness for large-space applications.
- 500--600W High Power -- TR300 at 500W and TR600 at 600W deliver the energy needed to project convincing solar simulation across multi-story spaces.
- CRI 95 Ra -- Exceptional color accuracy across the full tunable CCT range. Materials, skin tones, and surfaces render with sunlight-grade fidelity.
- Rayleigh Scattering Optics -- Nano-particle diffusion generates the blue sky field surrounding the bright sun disc for a complete overhead sky experience.
- BLE Mesh 5.0 / DALI / 0-10V -- Professional-grade control interfaces for building automation integration, scheduling, and remote management.
- Circular Architecture -- Round housing creates a natural porthole-to-sky aesthetic that enhances any ceiling design with organic form and dramatic visual impact.

Installation
Step 1: Identify structural ceiling mounting points rated for the panel weight (30 kg for TR300, 40 kg for TR600) plus appropriate safety margin. Use the circular template to mark the cutout.
Step 2: Cut the circular ceiling opening to 585mm diameter (TR300) or the corresponding dimension for TR600. Install the structural bracket and safety cable.
Step 3: Mount the high-power LED driver in an accessible location above the ceiling. Connect to mains power and route the high-current cable to the mounting position.
Step 4: Secure the TR panel to the structural bracket. Connect power, verify safety cable engagement, and power on. Configure CCT and scheduling via BLE Mesh or DALI interface.
Frequently Asked Questions
How is the TR different from the T-series square panels?
The TR and T share the same sun simulation technology but differ in three key ways: (1) The TR is round, the T is square. (2) The TR offers full CCT tunability from 2,100K to 7,800K, while the T is fixed at 6,500K. (3) The TR's circular form creates a more natural porthole aesthetic. Choose the TR for maximum versatility and organic form; choose the T for pure fixed-daylight sun realism in square ceiling grids.
How heavy is the TR, and what ceiling support is needed?
The TR300 weighs 30 kg and the TR600 weighs approximately 40 kg. These are substantial fixtures that require structural ceiling support -- not standard drywall. Mounting points should be secured to steel framework, concrete, or engineered wooden beams. Professional structural assessment and installation is essential.
Can the TR simulate a sunrise-to-sunset cycle?
Yes. The tunable CCT range (2,100K--7,800K) combined with BLE Mesh 5.0 and DALI control enables fully automated circadian scheduling. Program a gradual warm sunrise, bright midday peak, golden-hour descent, and warm evening fade. The sun disc intensity and sky color shift together for a cohesive solar simulation.
What is the minimum ceiling height recommended?
We recommend a minimum ceiling height of 4m for effective sun disc projection. The TR performs optimally at heights of 5-15m, where the sun disc and surrounding sky create maximum visual impact. For standard residential ceilings (2.4-3m), the ER series is a better choice.
Does the TR produce UV radiation?
No. The SkyLume TR uses LED technology that produces no ultraviolet radiation. The sunlight simulation is purely visible-spectrum. This makes it safe for artwork, furniture, and prolonged human exposure without any UV-related concerns.
Can the TR be paired with other SkyLume models?
Absolutely. The TR works well as a central sun feature surrounded by E-series or P-series panels that provide broader ambient sky coverage. In large atriums, combining a TR for the sun with surrounding panels for the sky creates a complete overhead environment.
What warranty is included?
Every SkyLume TR panel ships with a 2-year manufacturer warranty covering defects in materials and workmanship. High-power LED drivers are warranted separately for 2 years. Rated lifespan exceeds 15,000 hours of operation.
Is the TR energy-efficient for its output?
Given its extraordinary luminous output (20,000+ lumens), the TR achieves competitive efficiency for a sun simulation fixture. The 500-600W power consumption is high in absolute terms, but the luminous efficacy and the quality of the optical output represent excellent value compared to alternative approaches to achieving similar sun simulation effects in large spaces.
