Where rectangular panels follow conventional ceiling grid logic, the ER breaks free with a bold round form factor that draws the eye upward and holds it.\u003c\/p\u003e\u003cp\u003eInside the circular housing, Rayleigh scattering nano-diffusion optics reproduce the physics of Earth's atmosphere. Short-wavelength blue light scatters through nano-scale particles suspended in an optical medium, generating a gradient of sky that appears to extend infinitely beyond the surface. The effect is not a printed image or a blue LED glow -- it is optically generated sky with genuine perceived depth.\u003c\/p\u003e\u003cp\u003eAvailable in two diameters, the ER300 delivers a compact 500mm visible sky area within a 600mm outer frame, while the ER600 expands to an 800mm sky view within a 900mm housing. Both models feature a tight 1.5-degree vertical beam angle that projects concentrated daylight straight down, making the ER ideal for focused overhead illumination above dining tables, reception desks, reading areas, and architectural feature points.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircular Porthole Design\u003c\/strong\u003e -- Round form factor creates a dramatic architectural statement.

The circular form naturally draws the eye and feels more like a genuine portal to the sky. In design terms, the round shape adds organic softness to angular interiors, making it ideal for residential dining areas, hotel lobbies, and spa environments where a more natural aesthetic is desired.\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 cutout diameter required?\u003c\/summary\u003e\u003cp style=\"margin-top:8px;opacity:0.85\"\u003eThe ER300 requires a 585mm circular cutout for its 600mm outer diameter housing.

Minimum ceiling void depth is 220mm to accommodate the panel body and driver.\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 ER panel?\u003c\/summary\u003e\u003cp style=\"margin-top:8px;opacity:0.85\"\u003eThe ER300 weighs approximately 12 kg, and the ER600 weighs approximately 25 kg. Both are designed for secure ceiling mounting with integrated spring clips. For the heavier ER600, we recommend verifying that ceiling joists or support structure can handle the load.

However, an optional surface-mount adapter ring is available that allows the panel to sit flush against the ceiling surface without a cutout. Contact our support team for the surface-mount accessory. Note that surface mounting adds approximately 230mm of visible depth below the ceiling plane.\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 makes the 1.5-degree beam angle special?\u003c\/summary\u003e\u003cp style=\"margin-top:8px;opacity:0.85\"\u003eA 1.5-degree beam angle is exceptionally narrow -- it concentrates all light output into a tight vertical column directly below the panel. This creates a dramatic pool of daylight on the surface beneath, similar to the way sunlight enters through a real round skylight at midday. The narrow angle also reduces light spill onto surrounding surfaces, making the ER ideal for accent and task lighting applications.\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 it support circadian lighting schedules?\u003c\/summary\u003e\u003cp style=\"margin-top:8px;opacity:0.85\"\u003eYes. Through the Tuya smart platform, you can program automated sunrise-to-sunset schedules that gradually shift color temperature from warm 2,100K morning tones through 7,500K midday daylight and back to warm evening amber. DALI integration also supports building-level circadian automation in commercial environments.\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 ER panel ships with a 2-year manufacturer warranty covering defects in materials and workmanship.

While CoeLux systems can cost tens of thousands of dollars and require deep ceiling voids, SkyLume achieves a compelling sky effect at a fraction of the price with minimal installation requirements.
