Informal term conflating flicker box (electronic dimmer for light effects) with manual wobbling reflector technique to simulate firelight on set.
Overview
"Wobble Box" is not an established term in film technology. Anyone on set looking for a device that makes light fluctuate in brightness and color is usually looking for a Flicker Box — the electronic effect dimmer for fire, TV glow, water reflections, or faulty neon tubes. The term "wobble," on the other hand, refers to a completely different, purely mechanical technique in the lighting industry: the Wobbling Reflector, where a reflector is manually shaken during the shot to imitate the glow of fire.
Both create flickering light but are technically fundamentally different. We include the term here because it occasionally appears — and clarify what is actually meant. Anyone who hears "Wobble Box" should ask whether the Flicker Box as a device or the reflector trick is meant.
What is Usually Meant: The Flicker Box
The Flicker Box is the established industry term for an effect dimmer that varies the level of one or more channels according to a random or effect curve. This allows for the simulation of invisible light sources motivated only by the image: the shimmering of a fireplace, the restless glow of a television on faces, blue-green water reflections, or the pulsing of a broken fluorescent tube. Controls typically allow you to set the speed and upper/lower brightness limits; multiple channels make it possible to make lamps from different angles fluctuate against each other, thus creating moving shadows.
| Device | Channels | Key Specifications |
|---|---|---|
| Magic Gadgets Shadowmaker | 3 isolated dimmers | 20 A per channel; 16 programs (fire, candle, TV/monitor, screen, thunderstorm, various chasers); channels interactively random; external dimmers controllable via signal connector |
| movie-intercom LFX Master (DMX) | up to 3 channels | high-resolution flicker curves for fire with shadows and TV-RGB; separately controllable via external DMX console |
Specific wattage, dimension, or Kelvin values for a "Wobble Box" as an individual product do not exist — no manufacturer uses the term. The data above represents key specifications of actual Flicker Box devices.
What "Wobble" Actually Describes: The Reflector Trick
The Wobbling Reflector is a low-budget technique to fake the glow of fire without actual fire. An open tungsten light is aimed at a (often golden) collapsible reflector, and the reflector is gently shaken back and forth during the shot. The broken, moving light on the face resembles fireplace glow. With an orange gel, it becomes candlelight; with a blue gel, TV flicker. This is not electronics, but manual labor — fast, cheap, and surprisingly convincing.
On-Set Usage
For reproducible, finely controllable effects, the crew reaches for the Flicker Box: The gaffer or board operator adjusts the rate and intensity live, coordinated with the acting and camera movement, using multiple angles for moving shadows in multi-channel operation. If money or time is lacking, the Wobbling Reflector will suffice. You should avoid the umbrella term "Wobble Box" on set — it is ambiguous and leads to misunderstandings when ordering from rental houses.
