## Beam angle is the **spread of light** measured in degrees from a light source. A narrow beam angle (15-30°) concentrates light into a focused spotlight. A wide beam angle (90-120°) spreads light across a large area. It determines whether a light acts as a spotlight or a flood.

## **How beam angle affects your lighting**

**Narrow beam (10-30°):** Concentrated, directional light. Creates dramatic spotlighting effects. Reaches further distances with more intensity. Used for accent lighting, hair lights, and background highlights.

**Medium beam (30-60°):** Versatile middle ground. Good for key lights on individual subjects. The most common range for portrait and interview lighting.

**Wide beam (60-120°):** Broad, even spread. Good for filling rooms, lighting backgrounds, and illuminating groups. Less intensity at any single point.

## **Fixed vs adjustable beam angle**

**Fixed beam:** Many LED panels and tube lights have a fixed wide beam angle (90-120°). You control the spread using external modifiers — barn doors narrow it, diffusion widens and softens it.

**Adjustable beam (zoomable):** COB lights like the Godox SL series, Nanlite Forza, and many Bowens-mount lights have a built-in reflector or Fresnel lens that lets you zoom the beam from spot to flood.

**Fresnel lens:** A special lens attachment that gives you smooth, adjustable beam control from 15° to 60°. Produces beautiful, even light. Common in cinema and broadcast lighting.

## **Choosing the right beam angle**

For **portrait key light:** A modifier on a COB light gives you the most control. Start with a softbox (wide, soft) and add a grid to narrow it if needed.

For **accent and rim lighting:** Narrower beam (15-30°) concentrates light where you want it without spilling onto unwanted areas.

For **room and background fill:** Wide beam (90°+) panels or bounced COB lights spread light evenly.

For **maximum flexibility:** Buy COB lights with Bowens mount — you can attach any modifier to change the beam angle for any situation.

## 

A COB light with a Bowens mount is the most versatile lighting investment because you can attach softboxes (wide, soft), reflectors (medium, focused), barn doors (controlled), or Fresnel lenses (spot to flood) — one light, infinite beam angles.
