Wall washer lights are linear or compact LED fixtures that spread even light up a vertical surface, so facades, bridges and signage read as one continuous wash instead of a row of bright spots. GS LIGHT builds them for architects, lighting designers and signage contractors in IP66 rated aluminum housings with CRI 80 or higher. Each series supports DMX512, DALI or 0 to 10V dimming, beam angles from 10° to 60°, and a rated life above 50,000 hours.
A wall washer light is an outdoor LED fixture that spreads even light up a vertical surface, so the wall reads as one smooth plane. Wall grazing does the opposite: the fixture sits close to the surface and rakes light across it to raise texture on stone, brick or concrete.
GS LIGHT builds wall washers in linear bars and compact bodies, plus the flexible WF series that bends along curved surfaces. Beam angles run from a 10° narrow throw for tall towers to 60° for close mounting, with 10x60° and 20x45° asymmetric optics for wide, low walls. Single color, RGB and RGBW versions run on DMX512 for scene changes across a whole building facade lighting installation.
Because these fixtures live outdoors, protection matters as much as optics. GS LIGHT uses 6063 aluminum alloy bodies, SUS304 stainless steel screws and mechanical sealing to reach IP66, which covers rain, dust and coastal air on villas, bridges, commercial buildings and signage.
GS LIGHT uses OSRAM or CREE LEDs with CRI 80 or higher, depending on the series, so stone, glass, concrete and metal facades hold their daytime color at night. High CRI keeps branded signage and cladding materials from shifting color under the wash.
Each LED module is binned for uniform color temperature across fixtures. Order 50 units for a hotel facade and the color matches within 3 MacAdam steps, so the wash runs evenly along the surface with no visible hot spots or color shift between fixtures.
These chips hold 70% of their initial output after 50,000 hours of operation. On a bridge or a high rise facade, access costs more than the fixture, so that number decides the maintenance budget. Test reports for each series sit with the rest of the GS LIGHT certifications.
6063 aluminum alloy housings with an outdoor powder coat resist UV, salt spray and the expansion that comes with daily temperature swings, from minus 20 °C to 50 °C. For coastal projects, electrophoretic pretreatment under the powder coat and SUS316 stainless fasteners can be specified, and the salt spray test standard and duration are available on request.
Aluminum conducts heat at roughly 200 W/mK against 15 to 50 W/mK for steel, so the housing pulls heat away from the LEDs far faster. The diodes stay inside their rated temperature even at full output in direct sun. Lumen depreciation stays slow and service life runs past 50,000 hours.
Every fixture ships with sealed gaskets and waterproof cable glands, so you can mount it on bridge guardrails, facades or outdoor signage and leave it there. Wattages run from 12W on the linear LJ series to 144W on the WL92 series, so a garden wall and a 20 meter tower each get the right output.
Static white or RGBW dynamic lighting.
Static architectural washing uses a fixed white, typically 3000K, 4000K or 5000K, on DALI or 0 to 10V, for hotels, offices, museums, villas and landscape walls. RGBW dynamic lighting uses DMX512 for scenes and synchronized effects on hotel facades, landmarks, bridges, shopping malls and event venues. Most facades need the first; choose the second when someone will program and run the scenes after handover.
Control brightness and color remotely over DMX512, DALI or 0 to 10V.
DMX512 drives full RGBW scenes and synchronized effects across hundreds of fixtures. Hotel branding, bridge schemes and event venues run on it. Scenes can be programmed to change at set intervals for holidays, seasons or exhibition dates. Single color, RGB and RGBW versions are available on the WF, LJ and WS38 series.
DALI and 0 to 10V suit buildings that run one control system for everything. Choose DALI when the wall wash has to sit inside a building wide control network, and 0 to 10V when a manual dimmer or an automation panel only needs to set brightness. Both dim without flicker.
All models use sealed terminals and IP rated control interfaces, so DMX and DALI cabling can run outdoors without water reaching the connection points.
Beam angles of 10°, 15°, 30°, 45°, 60°, 10x60° and 20x45° are available, with an 18+55° asymmetric option on the WH38, WL64 and WL92 series. Narrow beams reach the top of a tower from ground level; wide and asymmetric beams cover low, broad walls from close range.
As starting points: for grazing 3 to 8 meter walls, mount 0.2 to 0.5 meters from the face with 10° or 15° optics. For standard facades of 5 to 15 meters, mount 0.5 to 1.5 meters out with 15° or 30° optics. For a wide wash on 5 to 10 meter walls, move back to 1 to 3 meters with 30° or 45° optics. High facades of 15 to 30 meters need 10° or 15° optics with the position set by the project, and 10x60° or 20x45° optics spread light sideways along low, wide walls. Surface texture, finish and mounting height all shift these numbers, which is why GS LIGHT runs a photometric layout for project quantities before anything ships.
The right angle removes shadows, reveals texture on stone and glass, and keeps light off windows and walkways where it would glare.
Start from the surface and the effect, then pick the series:
Standard facades and boundary walls: WS38 and WG36, with AC200 to 240V input on the WG36 where a DC supply is impractical.
High rise facades and long throws: WL64 and WL92, from 48W to 144W.
Curved and irregular surfaces: the flexible WF series, which bends along columns, arches and bridge rails.
Windows close to the fixture line: WH38, WL64 or WL92 with the 18+55° asymmetric optic.
RGBW dynamic facades: WF, LJ and WS38 on DMX512.
Garden walls and low elevations: the linear LJ series from 12W.
Send an elevation drawing with the facade height and width, the mounting positions, the effect you want, static white or RGBW, and the control system. We return fixture selection, beam angles, spacing, power, the DMX configuration and a photometric layout with the BOQ.
Wall wash fixtures from GS LIGHT light demanding exterior and interior architectural projects:
Mr. Carlos
This chain-shaped WF Series wall washer light is extremely easy to install! It perfectly fits the curved exterior wall of our villa. The lighting effect is even softer than expected. The IP66 waterproof rating has never caused any problems even during the rainy season. It's a great value for money!
Mr. Emma
We chose this wall washer light for the exterior of the hotel. The light bulbs have a high brightness. The 10° narrow beam precisely highlights the LOGO. The anti-glare grille design ensures that guests don't get dizzy when taking photos. The construction team said that this material is much more durable than the previous ones they used!👍

Wall washing spreads even light across a surface from a distance and hides texture; wall grazing sits close to the wall and rakes light along it to raise texture. Use washing on flat cladding, glass and painted walls. Use grazing on stone, brick and fluted concrete where the relief is the feature.
It depends on the effect. For grazing, 0.2 to 0.5 meters from the wall with 10° or 15° optics. To wash a 5 to 15 meter facade, 0.5 to 1.5 meters out with 15° or 30° optics. For a wide, even wash on a lower wall, 1 to 3 meters back with 30° or 45° optics. Linear wall washers usually run end to end in a continuous line. Ask for a photometric layout before ordering quantities.
Mount them at the base of the wall aiming up, or along the top edge aiming down, using the adjustable brackets supplied. Keep fixtures clear of planting beds and walkways where lenses collect soil and catch glare. Near windows, the 18+55° asymmetric optic pushes light up the wall instead of into the room.
DMX512, DALI and 0 to 10V, depending on the series. DMX512 drives RGBW color scenes, gradients and chase effects across hundreds of fixtures from one console. DALI suits buildings running a central control network, and 0 to 10V handles simple brightness from a dimmer or automation panel. RGB mixes color from three channels; RGBW adds a white chip, which gives cleaner whites and softer tones, so choose RGBW when the facade spends most nights in white. All control terminals are sealed for outdoor wiring.
Fixture price depends on wattage, optics and control type, and on tall facades the installation labor usually matches or exceeds the fixture cost. Standard white models in common beam angles ship in about 2 weeks; custom RGBW configurations and large project quantities take 3 to 4 weeks. Send wall dimensions, mounting height and control requirements for a quote within 24 hours.
Every wall washer series carries a 3 year warranty and an IP66 rating. Bodies are 6063 aluminum alloy with outdoor grade electrostatic coating and SUS304 stainless steel screws, which holds up in coastal and industrial air. Input is DC24V across the range, with AC200 to 240V on the WG36 series.
