Filmmaking Dictionary: Number 1 / 1×2 LED Panel
Definition
A 1×2 LED panel is a rectangular lighting-fixture category with a face roughly one by two feet. It is also commonly called a 2×1 panel. The order of the numbers usually describes the same general format rather than a different lighting technology.
The size label does not specify exact external dimensions, wattage, brightness, colour control or weather protection. Those depend on the model and its accessories.
How the Rectangular Shape Is Useful
A rectangular source can suit a two-person interview, a strip-like reflection or a setup where the crew wants a broader source along one axis. Rotating it changes the orientation of the emitting area and its reflections.
That does not make it automatically soft in every direction. Apparent source size from the subject, distance and the fixture’s optics determine the shadow. A long narrow reflection may be useful on one object and distracting on another.

Bare Panel Versus Modified Source
Some panels are designed as soft sources; others use harder optics and accept diffusion or a softbox when a softer result is wanted. A modifier can change spread, output and the effective source size.
When comparing fixtures, use the same conditions: distance, colour setting, beam configuration and modifier. A high bare-fixture reading is not directly comparable with another unit measured through a large softbox.
Planning the Setup
- Confirm the actual fixture and modifier dimensions.
- Allow room for the yoke and its movement.
- Check stand and mounting compatibility for the complete load.
- Plan power and cable routing.
- Test fan noise for dialogue recording.
- Check colour and flicker at the intended camera settings.
The longer body and a fitted softbox can affect balance and available clearance. A stand suitable for a small bare panel may not be the right support for a larger modified fixture in the proposed position.
Example on Set
For a seated two-shot, the gaffer places a rectangular panel through diffusion to create a broad key. Moving the source farther away may help even the exposure between the performers, while also changing apparent size and softness. The crew checks both faces and adjusts the actual setup rather than relying on the fixture’s label.

Frequently Asked Questions
Is a 1×2 twice as bright as a 1×1?
Not necessarily. Size, power, efficiency, beam optics and diffusion all affect measured output.
Are 1×2 and 2×1 different sizes?
They commonly refer to the same rectangular category. Confirm the supplier’s exact model and dimensions.
