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.\u003c\/p\u003e\u003cp\u003eUnlike 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.\u003c\/p\u003e\u003cp\u003eAvailable 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.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMost Realistic Artificial Sun\u003c\/strong\u003e -- Round form factor with visible sun disc and surrounding blue sky creates the most convincing overhead sun simulation available in any artificial skylight.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTunable CCT (2,100K--7,800K)\u003c\/strong\u003e -- Unlike the T-square (fixed 6,500K), the TR offers full spectrum tunability for circadian scheduling, mood lighting, and dynamic sky simulation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u0026gt;20,000 Lumens\u003c\/strong\u003e -- Extraordinary luminous output from the TR300; the TR600 exceeds this further.

(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.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"margin-bottom:12px;padding:12px;border:1px solid rgba(128,128,128,0.2);border-radius:8px\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600\"\u003eHow heavy is the TR, and what ceiling support is needed?\u003c\/summary\u003e\u003cp style=\"margin-top:8px;opacity:0.85\"\u003eThe 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.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"margin-bottom:12px;padding:12px;border:1px solid rgba(128,128,128,0.2);border-radius:8px\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600\"\u003eCan the TR simulate a sunrise-to-sunset cycle?\u003c\/summary\u003e\u003cp style=\"margin-top:8px;opacity:0.85\"\u003eYes. 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.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"margin-bottom:12px;padding:12px;border:1px solid rgba(128,128,128,0.2);border-radius:8px\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600\"\u003eWhat is the minimum ceiling height recommended?\u003c\/summary\u003e\u003cp style=\"margin-top:8px;opacity:0.85\"\u003eWe 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.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"margin-bottom:12px;padding:12px;border:1px solid rgba(128,128,128,0.2);border-radius:8px\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600\"\u003eDoes the TR produce UV radiation?\u003c\/summary\u003e\u003cp style=\"margin-top:8px;opacity:0.85\"\u003eNo. 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.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"margin-bottom:12px;padding:12px;border:1px solid rgba(128,128,128,0.2);border-radius:8px\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600\"\u003eCan the TR be paired with other SkyLume models?\u003c\/summary\u003e\u003cp style=\"margin-top:8px;opacity:0.85\"\u003eAbsolutely. 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.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"margin-bottom:12px;padding:12px;border:1px solid rgba(128,128,128,0.2);border-radius:8px\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600\"\u003eWhat warranty is included?\u003c\/summary\u003e\u003cp style=\"margin-top:8px;opacity:0.85\"\u003eEvery SkyLume TR panel ships with a 2-year manufacturer warranty covering defects in materials and workmanship.
