Lee Filters Marius Red Gel Filter Roll 48" x 25

Professional lighting gel for creative imaging

The Lee Filters Marius Red gel roll supplies a vivid red hue for photographers, videographers and stage-lighting professionals who need consistent colour effects across large fixtures or multiple units. Its 48-inch width and 25-foot length allow custom cutting to fit fresnels, panels, softboxes or window gels without seams. The material is designed for colour accuracy so the red tone remains predictable from frame to frame.

Heat-resistant construction for sustained output

Built from durable, heat-resistant stock, the filter tolerates continuous output from tungsten, HMI or high-power LED sources without warping or fading during long takes or multi-hour productions. Minimal light-loss characteristics keep exposure changes small, so gaffers can balance the gel with other sources without large stop compensation. The roll format lets technicians replace scorched sections quickly instead of discarding an entire sheet.

Physical limits of gel filtration

As a subtractive colour medium, the gel darkens the beam and shifts the spectrum; it cannot add output or correct colour temperature the way a CTO or CTB filter would. Deep saturation inevitably reduces transmission, so very high-key scenes may require brighter fixtures or wider apertures. The polyester base will eventually degrade under intense UV or extreme heat, so periodic inspection and replacement are part of normal workflow.
