Professional Lighting Gel Filter Roll

The Lee Filters 1.5 CTS gel filter roll measures 25 feet by 48 inches and fits a 1-inch core. It is built for photographers, videographers and lighting technicians who need large-format diffusion material for studio or on-location work. The roll provides enough surface area for multiple setups from a single piece.

Diffusion Limits of Polyester Gel

As a polyester-based gel, the material softens and spreads light beams to reduce contrast ratios between highlights. It cannot withstand sustained high temperatures from certain continuous fixtures without risk of warping or colour shift. The fixed 1.5 CTS density offers a single diffusion strength rather than variable control.

1.5 CTS Density Rating

The 1.5 CTS specification defines the exact level of contrast reduction and beam spread this filter delivers. Buyers who need a different diffusion intensity or a non-polyester substrate such as grid cloth or spun material must select an alternative product from the Lee Filters range.

Questions about this item

What does the 1.5 CTS rating mean for my lighting setup?

The 1.5 CTS rating indicates a quarter-strength colour temperature straw gel. It warms the light slightly while softening and spreading the beam, reducing contrast between highlights for more balanced results.

How does the 25' x 48" roll size translate to practical use?

The roll provides 25 feet of gel material that is 48 inches wide, yielding ample sheets for multiple studio or on-location shoots and allowing custom cuts for various fixture sizes.

Will the 1" core fit my existing gel frames and holders?

The roll is wound on a standard 1-inch core, which is compatible with most professional gel frames, roll holders and dispensing systems used in studio and location lighting.
