At Guojin Building in Jincheng, RGBW LED window-sill lights illuminate individual window bays across the office facade. The repeated openings form a coordinated lighting pattern, while changes in colour give the building different night-time appearances.
Rather than tracing the building’s perimeter, the lighting follows its individual window bays. Illuminated openings repeat across the office blocks and continue around the corners, connecting separate elevations through a consistent window-grid pattern.
CRANE supplied 12 W RGBW LED window-sill lights with IP66 protection and DMX512 control. The luminaires provide the basis for coordinated facade colour scenes. The recorded supply period was October 2024 to May 2025.

Direct Light Within the Window Reveal
The window bay is the basic lighting unit. Sill position, recess depth and beam direction determine how its surfaces are illuminated and how the grid appears from the street. Repeating a tested mounting detail helps maintain consistent results across floors and corners.
Organise RGBW Scenes with DMX512
DMX512 provides colour and intensity control for compatible RGBW fixtures. Windows can be grouped by floor or facade zone for shared colours or coordinated transitions. Channel allocation, addressing and controller capacity should be defined from the final luminaire schedule.
Limit Glare at Occupied Office Windows
Window-sill lighting must also be comfortable from inside the building. Fixture shielding, aiming and brightness should reduce direct views of the source and reflections in glazing. A full-scale sample bay allows the exterior effect and indoor comfort to be assessed together.
Design focus: repeatable window-bay details, coordinated RGBW zones and indoor visual comfort.

PROJECT VIEWS
A Repeated Window Pattern, Multiple Colour Scenes
The window openings establish the facade pattern; RGBW colour scenes change the building’s night-time character without losing that rhythm.

LED Window-Sill Lights
Project-supplied fixture category · Window bays
CRANE supplied 12 W RGBW LED window-sill lights for the repeated office window bays. IP66 protects against outdoor exposure, while DMX512 supports coordinated colour and dimming scenes across compatible luminaires.
HL Slim-Width wall washers offer a separate solution for narrow facade surfaces beside or between windows. Choose the optic and setback for the required surface coverage; this category does not replace the window-sill luminaire used to light individual openings.

Which RGBW fixtures did CRANE supply for Guojin Building?
CRANE supplied 12 W RGBW LED window-sill lights with IP66 protection and DMX512 control. The fixtures illuminate individual window bays, creating the building’s repeating facade light pattern.
How are repeated RGBW windows controlled with DMX512?
DMX512 can adjust colour and brightness in compatible RGBW luminaires. Fixtures may be addressed individually or grouped by floor and elevation, depending on the specified controllers and channel plan. The final window count determines the necessary control capacity.
What matters when specifying LED window-sill lights?
Check window width, sill depth, reveal geometry, fixing points and drainage before choosing a luminaire. Allow for cable routing and servicing without affecting window seals. Beam direction should suit the opening instead of sending light across the glass.
How can RGBW facade lighting avoid glare inside offices?
Use recessed mounting, suitable shielding and controlled output to keep the source out of occupants’ direct sightlines. Check reflections on glazing and evaluate a typical window bay from the room and the street before repeating the detail.
Can CRANE customise RGBW window-sill lighting for a new project?
Yes. CRANE can review custom dimensions, RGBW configurations and DMX512-compatible control options. Share typical window sections, elevations, fixture quantities, preferred light scenes and mounting limitations so we can assess a suitable supply proposal.
