A Fresnel spotlight is a theatrical and film lighting fixture with a Fresnel lens , which produces a soft, evenly distributed beam of light . This type of lamp is often used for background lighting, side lighting, and general fill lighting on stages, in film studios, and at events.
Features of a Fresnel spotlight
✅ Fresnel lens – A lens with concentric rings that provides a wide, soft light distribution .
✅ Adjustable focus – By moving the light closer to or further away from the lens, you can make the beam narrower or wider .
✅ Soft and even light – No hard edges, ideal for a natural look.
✅ Barn doors (flaps) – These allow you to shield and direct the light beam.
✅ Use of halogen or LED – Modern variants are energy-efficient LED luminaires.
How does a Fresnel spotlight work?
🔹 A Fresnel lens ensures that the light is spread softly and diffusely , without creating harsh shadows .
🔹 The lamp can be moved closer to or further away from the lens to narrow or widen the beam.
🔹 Barn doors can be used to frame the light beam and reduce light leakage.
Fresnel spot vs. LEKO (Ellipsoidal Reflector Spotlight)
| Characteristic | Fresnel spot | LEKO (Ellipsoidal Spotlight) |
|---|---|---|
| Light beam | Soft and diffuse | Tight and focused |
| Demarcation | With barn doors, but not exactly | With shutters, sharp contours |
| Focus setting | Spot flood adjustment | Precise focus |
| Gobo compatibility | No | Yes (project patterns) |
| Usage | Background and filling light | Key-lighting, patterns, contours |
💡 Use a Fresnel spot for soft, wide lighting and a LEKO for tight, sharp lighting .

LED Fresnel vs. halogen Fresnel
🔹 LED Fresnel lamps are more energy efficient, cooler running and have a longer lifespan .
🔹 Halogen Fresnels are still used for their warm light quality , but are slowly being replaced by LED technology.
