Lee Filters 1/2 CTO Gel Filter Sheet 24x21

SKU CH-ZKS0-50V2M

A 1/2 CTO gel sheet converts daylight to tungsten balance and measures 24 by 21 inches for broad coverage

  • Precise 1/2 CTO correction matches daylight to tungsten lighting
  • High-quality gel material resists tearing and fading over time
  • Withstands high studio-light temperatures without colour shift or deformation
  • Large 24 x 21 inch sheet covers broad light sources
  • Can be cut to custom sizes for versatile lighting setups

Purpose and audience

This half CTO gel sheet converts daylight sources to match tungsten lighting for photographers and videographers who need precise colour balance. The generous 24 by 21 inch dimensions cover large fixtures or can be trimmed for smaller modifiers.

Upgrade path

It replaces makeshift gels or lower-grade filters that fade, tear or shift hue under sustained heat. The jump is worth it when consistent colour accuracy across long shoots matters more than the lowest cost per sheet.

Installation notes

The material cuts cleanly with scissors or a rotary cutter and fits standard gel frames or tape mounts. The main risk is creasing the sheet during handling, which can create visible lines in the light output.

Questions about this item

What are the sheet dimensions so I know if it covers my light panel?

The gel measures 24 inches by 21 inches, giving broad coverage for large studio heads or window frames.

How do I attach the gel without it sagging or melting under hot heads?

Cut the sheet to size, then secure the edges with heat-rated tape or a gel frame clipped to the barn doors of the fixture.

When should I replace the sheet after repeated studio use?

Swap it out once the orange tint fades unevenly, the surface scratches enough to scatter light, or the material becomes brittle from heat cycles.
