Overview

Unleash Your Lighting Potential with the Quasar Science Q-LED Crossfade

The Quasar Science Q-LED Crossfade Linear 15W Bi-Color LED Lamp provides unparalleled versatility for lighting any scene. Adjust the lamp from a warm 2000K candle light to a cool 6000K overcast daylight, making it ideal for both actors and environments. Its unique design allows for stacking into large arrays, creating expansive LED panels with exceptional energy efficiency.

Key Features:

  • X-Fade White Light: Seamlessly blend between Candle Light (2000K) and Overcast Daylight (6000K) diodes to achieve a balanced and variable color spectrum.
  • Low Profile Design: Easily concealable in tight spaces, the Q-LED Linear LED lamp can be mounted against walls or ceilings without compromising framing.
  • Self-Ballasted: Eliminates the need for external power supplies or ballasts, saving time and reducing clutter.
  • Dimmer Compatible: Works with most dimming systems for precise lighting control.
  • Expandable and Scalable: Stack multiple units to create large LED panels or extend linear lighting as needed.

Pros & Cons

👍 Pros

  • Wide 2000K to 6000K bi-color range eliminates the need for color correction gels across most common white-light scenarios
  • Self-ballasted design simplifies rigging by removing external power supplies and cable clutter
  • Slim tube form factor fits into tight spaces and practicals where conventional fixtures cannot hide
  • Stackable design lets you scale from a single accent tube to a full panel array as needed
  • 15W power draw keeps energy costs low and reduces heat output on set

👎 Cons

  • 15W output is limited, so the lamp works best as an accent, fill, or practical rather than a key light
  • Tube form factor produces a linear light pattern that may require diffusion for even, broad coverage
  • No built-in wireless or DMX control — dimming requires a compatible external dimmer system
  • Limited to white-light crossfade with no RGB or colored gel emulation capability

Frequently Asked Questions

It blends continuously from 2000K warm candle light to 6000K cool daylight, letting you dial in any white point across that range without swapping gels or tubes.
No. The lamp is self-ballasted, so it runs directly from a standard light socket without any external driver or power supply.
Yes. The units are designed to stack side by side into arrays, allowing you to build larger LED panels scaled to the size you need.
It works with most standard dimming systems, giving you smooth intensity control from full output down to low levels.
At just a tube-lamp form factor, it can be mounted flush against walls, ceilings, or inside practical fixtures where a conventional light would be visible in frame.
