Architectural Lighting

This downlight beam angle guide explains how narrow, medium, and wide beams affect light distribution, spacing, glare, and visual comfort in real spaces. In practice, this guide shows when to use narrow, medium, and wide beams with clear examples. It is written for homeowners, architects, and contractors who want downlights that look clean on site, not just on paper. How Beam Angle Changes What You See A downlight does not “fill a room” by default. It creates a cone of light. The beam angle controls how tight or how wide that cone is. The same lumen package can look punchy, flat, or uncomfortable depending on the optics. For a clear technical definition, see the IES definition of beam angle. As a practical starting point for interior downlights: Visual comparison: narrow, medium, and wide downlight beam spreads at the same ceiling height. What “narrow vs wide” really means in a room Beam angle is not a style choice. It is a performance choice. It controls contrast, spacing, and visual comfort. As a result, you can use it to guide the eye, reduce fixture count, or avoid uneven bright spots. However, one key point remains: beam angle on a spec sheet is only part of the story. Real results depend on ceiling height, trim type, shielding, and the exact IES file for the fixture. Practical Rules for Choosing Beam Angles Use beam angle with three checks: ceiling height, spacing and the task. This keeps the layout simple and avoids the most common mistakes. Below are real-world examples you can apply immediately: Spacing, scallops, and glare control Beam angle also affects how light “prints” onto walls and ceilings. When downlights sit too close to a wall, you will see scallops. If they are too bright or too open, you can get glare and uncomfortable brightness at eye level. To predict wall scallops before installation, use our visual tool here: Lighting Scallops Visualizations. In addition, it helps you test distance-from-wall and spacing so the pattern looks intentional. When the project matters, the clean way to verify beam angle choices is a photometric check using the fixture’s IES file. This shows actual foot-candle levels, uniformity, and where glare risks appear. Real Examples: What Beam Angle to Use Use these examples as a starting point. They reflect typical design intent. Final selection should still be confirmed with the actual fixture optics and the IES distribution. Use this downlight beam angle guide as a reference when reviewing fixture cut sheets and IES files. 30° vs 60° Downlight Beam Angle: Which One to Choose A 30° beam concentrates light into a tighter area. As a result, it creates higher contrast and stronger highlights. It works well for accents, art, and focused task zones, but it can look spotty if used everywhere. A 60° beam spreads light wider for smoother coverage. In most cases, it reduces hot spots and allows wider spacing. It often works better for lower ceilings and general ambient lighting. Simple rule: use 30° when you want focus and contrast. Use 60° when you want even coverage and comfort. If you are unsure, start with a wider beam for the base layer, then add tighter beams only where you need emphasis. In many cases, if your layout looks “busy,” it is often a beam choice issue, not a fixture quality issue. Too many narrow beams create many bright circles. Too many wide beams can flatten the room and reduce visual hierarchy. Common Beam Angle Mistakes to Avoid What is a downlight beam angle? A downlight beam angle is the spread of the main light cone leaving the fixture. Narrow angles concentrate light into a smaller area, while wide angles distribute light across a larger area. What’s the difference between 30° and 60° downlight beam angles? A 30° beam creates a tighter, brighter spot with higher contrast. A 60° beam spreads light wider for smoother coverage, which often reduces hot spots and allows wider spacing. Is 30° or 60° better for general lighting? In most rooms, 60° (or 40°–60°) works better as a general lighting base layer because it looks more even. Use 30° for accents, feature areas, and targeted task zones. How does beam angle affect spacing between downlights? Wider beams usually allow larger spacing because the light overlaps more. Narrow beams need tighter spacing to avoid dark gaps and visible circles on the floor. Does a wider beam reduce glare? Sometimes, but not always. Glare depends on cutoff, shielding, and brightness at typical viewing angles. However, very tight beams can create stronger contrast and more noticeable hot spots if placement is not controlled. Why do I see scallops on the wall from my downlights? Scallops appear when downlights are placed too close to a wall or spaced in a way that creates a repeating pattern. Beam angle and distance-from-wall both change the scallop shape and intensity.

Use the scallops tool to test wall patterns, and reach out when you need a full plan that is ready for construction.

What Is BUG Rating in Outdoor Lighting? Backlight, Uplight, and Glare Explained BUG rating is a key metric used in outdoor lighting design to control light pollution, glare, and unwanted spill. It helps designers, engineers, and inspectors understand how a fixture distributes light beyond the target area. If you work with photometric plans, site lighting, or exterior fixtures, understanding BUG ratings is essential for code compliance and visual comfort. What Does BUG Rating Mean? BUG is an acronym that describes three types of unwanted light output from outdoor fixtures. Each component is measured separately to give a clear picture of fixture performance. The Three BUG Components Each BUG rating is expressed as three numbers, such as B2 / U1 / G3. Lower values mean better control of light. BUG ratings are defined by the IES (Illuminating Engineering Society) and are commonly used in zoning ordinances and outdoor lighting standards. How BUG Ratings Affect Outdoor Lighting Design BUG ratings help ensure outdoor lighting provides visibility and safety without creating excessive glare or light trespass onto neighboring properties. Lighting Zones and BUG Limits Outdoor sites are classified into Lighting Zones (LZ0–LZ4). Each zone sets maximum allowed BUG values based on environmental sensitivity. The following tables display the thresholds for each subzone. BUG ratings are always evaluated using a fixture’s IES file and verified during photometric calculations. Example: BUG Rating in a Real Project In this residential exterior example, three wall-mounted fixtures were analyzed using photometric software and the manufacturer’s IES data. This rating shows moderate uplight and glare, which may be acceptable in residential zones but would likely require adjustment in more sensitive environments. Get a Professional Photometric Plan We create accurate photometric plans that verify BUG ratings, lighting levels, and code compliance. Final Takeaways BUG ratings are a critical part of modern outdoor lighting design. They help control glare, limit light pollution, and ensure fixtures perform as intended. If you need help verifying BUG ratings or preparing a compliant photometric plan, Stetra Lighting can support your project from fixture selection to final approval.

Lighting design is a crucial element in enhancing the functionality, aesthetics, and ambiance of any space. However, even with the best intentions, there are common mistakes that can compromise the effectiveness and impact of your lighting design. By being aware of these mistakes and avoiding them, you can create well-lit spaces that truly shine. Insufficient Lighting One of the most common mistakes is not providing enough lighting for a space. Inadequate lighting can lead to dark and uninviting environments, making tasks more challenging and reducing overall comfort. It is essential to carefully assess the lighting needs of each area and ensure that there are enough light sources to achieve the desired level of illumination. Poorly Balanced Lighting Balancing lighting is key to creating a visually appealing and functional space. A mistake often made is relying solely on one type of lighting, such as overhead fixtures or task lighting, while neglecting other areas. To avoid this, incorporate a combination of ambient, task, and accent lighting to create layers of light that provide adequate illumination and enhance the overall aesthetics. Ignoring Color Temperature Color temperature refers to the warmth or coolness of light, and it greatly impacts the atmosphere and mood of a space. A common mistake is disregarding the color temperature and using the same lighting throughout different areas. For instance, using cool white light in a cozy living room can create a harsh and unwelcoming environment. It is essential to consider the function and desired ambiance of each space and choose the appropriate color temperature accordingly. Inadequate Lighting Controls Neglecting proper lighting controls can result in inflexible and inefficient lighting designs. Lack of dimmers, timers, or occupancy sensors can lead to wasted energy and discomfort. Incorporating lighting controls allows for flexibility in adjusting lighting levels based on needs, saving energy, and creating a more user-friendly environment. Improper Placement of Lighting Fixtures The placement of lighting fixtures greatly influences the effectiveness of the lighting design. Common mistakes include improper spacing, uneven distribution, or placing fixtures in locations that cast shadows or create glare. To avoid these errors, carefully plan the placement of fixtures, consider the specific requirements of each area, and ensure that the lighting is evenly distributed to avoid inconsistencies. A common mistake with placing the wall washer light The most common mistake is placing the wall washer very near the wall which can result in not even distribution of the light on the wall. To correct this mistake make sure you are giving enough space between the light and the wall. Bellow image is showing the best practices so visually can see that 30 to 36″ of the wall is the safe spacing for placing the wall washer light. Neglecting Light Layering and Focal Points Lighting design should incorporate layers and focal points to create visual interest and highlight specific areas or objects. A common mistake is overlooking the importance of layering, relying only on general lighting without incorporating task or accent lighting. Additionally, failing to create focal points can result in a visually flat and uninspiring space. Consider using lighting to draw attention to architectural features, artwork, or focal points to add depth and character to the design. Avoiding common lighting design mistakes is essential to creating well-lit spaces that are functional, aesthetically pleasing, and comfortable. Achieve a successful lighting design by ensuring sufficient lighting, balancing different lighting types, considering color temperature, incorporating lighting controls, and embracing light layering and focal points. Enhance the overall appeal and functionality of any space with these essential techniques. Remember, thoughtful planning and attention to detail are key to avoiding these common mistakes and creating exceptional lighting designs.
