When designing architectural and commercial lighting, understanding how far a wall washer LED strip can project its light is crucial. These high-power LED strips are engineered to illuminate walls, facades, and large surfaces evenly, making them a popular choice for hotels, shopping malls, bridges, and office buildings.
In this article, we’ll explore how far wall washer LED strips can reach, factors that affect their performance, and how to choose the right one for your project.

How Far Can a Wall Washer LED Strip Illuminate a Wall?
The projection distance of a wall washer LED strip depends on several factors, including LED power, beam angle, and mounting height.
Typical Projection Distances Based on LED Power:
|
LED Power (W/m) |
Beam Angle |
Projection Distance |
|
10W-15W/m |
60°-90° |
1-3 meters |
|
18W-24W/m |
30°-60° |
3-5 meters |
|
30W-36W/m |
10°-45° |
5-8 meters |
|
High-power (50W/m+ ) |
10°-30° |
8-12 meters |
🔹 For small indoor spaces (e.g., hotel lobbies, art galleries, showrooms) → 1-3m projection is sufficient.
🔹 For large outdoor applications (e.g., building facades, bridges, landmarks) → 5-10m projection is needed.
Factors That Affect Light Projection Distance
Several factors influence how far the light from a wall washer LED strip will reach:
1️⃣ LED Power & Luminous Efficacy
✅ Higher wattage LEDs produce more lumens, extending the light throw distance.
✅ Efficient LED chips (e.g., 2835, 3030, or 5050 LEDs) offer better brightness at lower power consumption.
2️⃣ Beam Angle & Optics
✅ A narrow beam angle (10°-30°) focuses light further, increasing projection distance.
✅ A wide beam angle (60°-90°) spreads light across a broader area but reduces reach.
3️⃣ Mounting Height & Positioning
✅ Higher mounting (5m-10m) increases light coverage but requires higher wattage LEDs.
✅ Closer installation (1m-3m) creates intense wall washing effects.
4️⃣ Surface Material & Color
✅ Lighter-colored walls (white, beige, pastel) reflect more light, improving visibility.
✅ Darker surfaces (black, dark gray) absorb light, reducing effective distance.
Choosing the Right Wall Washer LED Strip for Your Project
✔️ For Indoor Spaces (Hotels, Offices, Galleries)
- Recommended Power: 10W-18W/m
- Beam Angle: 45°-90°
- Projection Distance: 1-3 meters

✔️ For Outdoor Architectural Lighting (Building Facades, Bridges, Monuments)
- Recommended Power: 24W-50W/m
- Beam Angle: 10°-45°
- Projection Distance: 5-10 meters
- Ideal For: Wall washing large buildings, highlighting structures
✔️ For Landscape & Park Lighting
- Recommended Power: 18W-30W/m
- Beam Angle: 30°-60°
- Projection Distance: 3-5 meters
- Ideal For: Pathways, garden walls, outdoor signs
