What Is a Lighting Gel?

Lighting gels, also known as colour filters or gel filters, are thin, coloured plastic sheets used in lighting design to colour the light emitted from spotlights. They are widely used in theatres, concerts, and other events to create a specific mood and atmosphere.

The gels are placed in front of the light source, such as a spotlight. As the light passes through the gel, it takes on the colour of the film. This allows lighting designers to produce creative and dramatic lighting effects. Gels are available in a wide variety of colours and shades, from subtle pastels to vibrant, intense hues.

They are typically heat-resistant to withstand the heat produced by conventional lights, although LED fixtures—which emit less heat—are becoming increasingly popular. Lighting gels are a simple yet effective tool for lighting designers to alter and enhance the visual impact of a performance or event.

What Do Colour Numbers Represent?

Colour numbers for lighting gels form a standardised system for identifying specific colour tones and shades. Each number corresponds to a precisely defined colour, making it easier to select and replicate lighting effects. This is especially important in professional stage and event lighting where consistency and accuracy of colour are critical.

Different manufacturers of gels, such as Rosco or Lee, have their own catalogues and numbering systems. Each number in these catalogues refers to a specific colour with defined properties such as hue, saturation, and light transmission. For example, a certain number might refer to a particular red or blue shade, with variations in brightness or intensity within that colour family.

This system enables lighting designers and technicians to create precise and repeatable colour effects. When a designer specifies a particular gel number in a design or specification, anyone implementing the design can use the exact same gel to achieve the intended effect. This ensures a consistent visual experience across different performances and venues.

What Should Be Considered When Buying Lighting Gels?

When buying lighting gels for stage lighting, several key factors should be taken into account to ensure they meet your needs:

• Heat resistance: Make sure the gels are heat-resistant, especially when used with conventional fixtures that produce a lot of heat. For LED fixtures, which emit less heat, lower heat resistance may be acceptable.
• Colour selection and quality: Look for a wide range of colours and strong saturation. High-quality gels should provide vibrant, fade-resistant colours that remain consistent over time.
• Material quality: Gels should be made of durable materials that do not tear or warp easily. Good material quality ensures longer lifespan and better performance.
• Sheet size: Make sure the gel sheets are compatible with the size of your spotlights. Cutting may be necessary to fit certain fixtures.
• Light transmission: Gels differ in how much light they allow through. Some are more transparent, while others significantly dim the light.
• Compatibility with your lighting setup: Check that the gels fit the holders or frames of your fixtures.
