Quasar Science Crossfade Tubes

The Quasar Science Crossfade is a professional bi-color LED tube light designed for film, television, and commercial production. It’s built around a simple idea that Quasar executes extremely well: clean, accurate white light with fast, predictable control, without unnecessary RGB complexity.

Fixture Overview

The Crossfade is a linear LED tube that allows smooth adjustment between tungsten and daylight color temperatures. Unlike RGB tubes, it focuses entirely on high-quality white light, making it ideal for crews who want consistent results without menu-diving or color-management overhead.

It’s designed to behave like a modern replacement for fluorescent tubes, but with better color, no flicker, and proper dimming control.

Key Characteristics

Bi-color LED tube (tungsten ↔ daylight)
Excellent color accuracy for skin tones
Even, soft linear output
Simple, fast operation
Designed for professional production workflows

The Crossfade is about getting white light right, quickly.

Light Quality and Output

The Crossfade produces a soft, even, linear source that wraps nicely at close distances and stays smooth across its length. It’s particularly effective for:

• key or fill light in tight spaces
• edge and eyelight
• wall washes and background separation
• practical-looking linear sources

Because the output is clean and spectrally stable, it holds up well across different cameras and mixed lighting environments.

Color and Control

The bi-color engine allows seamless adjustment between tungsten and daylight, making it easy to match practicals, HMIs, or existing ambient light.

Control is straightforward and production-focused. The Crossfade is designed to be adjusted quickly on set, without relying on complex app ecosystems or effects menus. This makes it popular with gaffers who value speed and trust over novelty.

Power and Workflow

The Crossfade is typically AC-powered, making it reliable for long shooting days without battery management. This suits studio environments, stages, and locations where power is readily available.

Its simplicity makes it fast to deploy and easy to hand off between crew members without explanation.

Mounting and Rigging

Like most professional tube lights, the Crossfade can be mounted in a wide range of ways:

• light stands with tube mounts
• clamps and grid rigs
• hidden behind set elements
• used visibly in frame as a practical

Its form factor makes it easy to integrate into both lighting setups and production design.
