Lighting in film is complex, important, but most of all experimental. Today we look at why you should use Fresnel lights in your next film.
Funnily enough, Fresnel lights were originally built in the 1800s for lighthouses and were not even considered in theatres, let alone film sets, until much further afield.
However, in the present day, it’s a mainstay and one of the most important lights in the world of theatre and film. That’s why in today’s article, we are going to find out more about Fresnel lights, how to use them correctly and where you can find them at an affordable price.
Let’s dive straight into it!
What are Fresnel lights?
Fresnel lights, also known in theatre as the “Fresnel lantern”, is a spotlight that allows the user to adjust the angle of the light. It allows you to move the lamp and reflector closer or further away to change the light direction and intensity.
Originally the light was created by Augustin-Jean Fresnel for use in lighthouses. Now it’s used in theatre and film daily.
The Fresnel light has been quoted as “Saving a million ships” – an interesting quote for a light predominantly used in show business.
The lens on this light form is interesting; it’s a lens made out of concentric rings formed to create the lens, instead of the usual lens being created from a thick cut piece of plastic or glass.

How do Fresnel lights work?
Fresnel lights are pretty simple lights to use whilst on a film set, but they are incredibly effective. The lights can come in various sizes and intensities.
They work by placing a lamp of various wattages (Depending on your preference) that sits on a track behind the Fresnel lens that sits in front of a spherical reflector. The Fresnel lens is a large aperture lens and short focus length, without a huge area behind it as a conventional design would need.
This reflector will now direct most of the light to the Fresnel lens, which creates this and produces a beam. This is encased within a unit of four brackets. There is a control at the back of the encasement that allows you to select whether the light beam is either a “Flooded” beam or a “Spotted” beam.
The four brackets are usually all fixed bar ones that you can alter. This allows you to add speed rings, bard doors and other add ons.
The final part of the Fresnel light is the AC power jack that provides electricity to the light itself. Sounds complex, but trust us, they’re incredibly easy to navigate.
What are fresnel lights used for?
Typically Fresnel lights are used in theatre and for lighting in film. They are used to light up television sets, commercial studios and theatres.
In terms of the usage on Television and film sets, the Fresnel lighting is incredibly diverse, and since you can adjust the size, angle and strength of the beam, it’s an asset on set.
It’s also a great asset for Three-point lighting, as with the larger, more intense beam, you can use it as a key light. For the lower intensity and narrow beam, you can then use this as a fill light.
Perfect for most scenarios, these lights are an incredibly diverse light source and one that will add value to your film set.
What accessories are there for Fresnel lights?
Now you know what a fresnel light is, how it works, and what they’re used for, here are some interesting accessories you can add to improve their performance.
The accessories are used to control the light and manipulate it to your preferred setup. The following accessories are quite common for the Fresnel light and allow you to do all sorts with the light, including softening the light to increasing the intensity.
- Round Scrims – reduces light intensity.
- Fresnels, do not have dimmers, but you can add these onto your lighting setup by using external dimmers and attaching them to the case – CineFoil is one of the most prominent dimmers.
- Four-leaf barn door – added onto the front bracket.
- Speed ring – allows you to attach softboxes to soften the light source.
- Change the colour using gels.
The accessories for your Fresnel lights allow you to manipulate the intensity, change the colour and much more. This allows you to be flexible with your lighting setup; you can even create a High Key lighting setup – perfect for commercials.
