Full Product Description

No windows? No real sunlight?

The Lumin 45° Slanted Sunlight Simulator brings a realistic sunbeam into any room, exactly like sunlight pouring through a skylight. Unlike flat LED panels, our patented 45° asymmetric beam creates slanted rays that cast natural shadows on your floor and walls.

45° Asymmetric Beam – True Slanted Sunlight

Unlike ordinary downlights or flat panels, the Lumin Blue Sky Light features a 45° asymmetric beam angle, simulating the natural angle of the sun shining through a window or skylight. This creates realistic slanted sun rays, natural shadow effects on floors and walls, and a sense of depth and spaciousness in any room.

Full-Spectrum Sunlight | Ra 95 | 2000K-8000K

High color rendering (Ra 95) delivers true-to-life colors. Tunable white light from 2000K (golden sunrise) to 8000K (clear blue sky) supports circadian rhythm and daily scenes. Dynamic circadian rhythm support is available via smart control.

Rayleigh Scattering Technology

The fixture scatters short-wavelength blue light while letting warm sunlight pass through, producing a deep, infinite blue sky effect. Simulates the exact physics of a blue sky.

Smart Control – Your Sky, Your Way

Control your sky light with ease:
DALI DT8 (tunable white)
Tuya / WiFi / Bluetooth / Zigbee / Casambi
RF remote or wall-mounted panel
App control for timing, scene setting, and color temperature adjustment

Why Choose the Lumin 45° Asymmetric Beam Skylight?

Realistic Slanted Sunlight – Unlike ordinary downlights or flat panels, the 45° asymmetric beam simulates the natural angle of the sun shining through a window or skylight, creating realistic slanted sun rays and natural shadow effects.
Scientifically Validated for Healthcare – Clinical studies of artificial skylights in healthcare environments show measurable benefits: increased sleep duration (+18 minutes), reduced stress, improved mood, and enhanced circadian rhythm support. These systems help patients and staff in windowless settings maintain natural day-night cycles.
Circadian Rhythm Support – Tunable white from 2000K to 8000K supports human-centric lighting strategies. The color temperature can automatically change according to sunlight rhythm via app setup, helping building occupants maintain healthy circadian rhythms.
No UV, IR, Mercury, or Glare – Environmentally friendly with no harmful emissions. Operating temperature range: -25°C to 55°C.
Customizable for Every Project – Custom sizes, control types, and finishes (black, gold, etc.) available upon request.

Installation Methods

Recessed into ceiling – Flush mount for clean, integrated look
