The lighting department is responsible for far more than just “making things bright.”
It controls exposure, contrast, color, and visibility — but just as importantly, it manages power, safety, logistics, and workflow across a set. A well-run lighting department is invisible when it’s working and immediately obvious when it isn’t.
This page breaks down how the lighting department is structured on professional film, television, and commercial productions, and explains what each role actually does on set. If you’re new to the department or trying to understand how the hierarchy fits together, start here.
What the Lighting Department Does
At its core, the lighting department is responsible for executing the Cinematographer’s lighting plan safely and efficiently.
That includes:
- Supplying and distributing power
- Rigging and positioning lights
- Controlling intensity, color, and direction
- Managing cable runs and distro
- Supporting camera movement and blocking
- Maintaining safety around heat, electricity, and overhead rigs
The department works in close coordination with camera, grip, and production. When lighting is organized, the entire set moves faster.
Lighting Department Hierarchy (Top to Bottom)
Gaffer
The Gaffer is the head of the lighting department and the chief lighting technician on set.
They work directly with the cinematographer to design and execute the lighting approach for the project. While the DP decides what the light should feel like, the Gaffer determines how to achieve it with the available crew, gear, and time.
The Gaffer oversees the entire lighting team, delegates tasks, and makes high-level technical decisions. On set, they are the final authority on lighting execution and safety.
2nd Electric (Best Boy)
The Second Electric (formerly known as Best Boy Electric) is the operational backbone of the lighting department.
They manage the crew, handle scheduling and paperwork, coordinate gear orders, oversee power distribution logistics, and act as the main liaison with production. While the Gaffer focuses on creative execution, the Second Electric makes sure the department actually functions.
If the lighting department runs smoothly, it’s usually because the Second Electric planned ahead.
Third Electric
The Third Electric is a senior lighting technician who supports both the Gaffer and Second Electric.
This role often involves supervising cable runs, managing distro on set, troubleshooting power issues, and mentoring less experienced electrics. On many productions, the Third Electric becomes the go-to person for hands-on problem solving when the department is stretched thin.
Responsibilities vary by show size, but the position sits between leadership and the working crew.
Daily Electric
A Daily Electric is a lighting technician hired on a day-by-day basis.
Dailies are expected to be competent, adaptable, and efficient. You might be running cable, placing fixtures, swapping lamps, adjusting levels, or supporting rigging and pre-lights. On some days you’ll be hands-on all shift; on others you may float wherever the department needs support.
Strong dailies get called back. Weak ones don’t.
Generator Operator (Genny Op)
The Generator Operator is responsible for supplying power to the set safely and reliably.
They manage generators, monitor loads, handle refueling, and coordinate power distribution with the lighting department. On location shoots without house power, the Genny Op is critical — one mistake can shut down production instantly.
Good generator operators are proactive, safety-focused, and calm under pressure.
How the Department Works Together
The lighting department is a system. Each role exists to support the others.
- The Gaffer defines the plan
- The Second Electric organizes the execution
- The Third Electric stabilizes the workflow
- Daily Electrics do the physical work
- The Genny Op keeps power flowing
When communication breaks down at any level, it shows up immediately on set — usually as delays, safety issues, or tension between departments.
Career Progression in the Lighting Department
Most people move through the lighting department gradually.
A common path looks like:
Daily/Third Electric ? Second Electric ? Gaffer
There’s no fixed timeline. Advancement depends on reliability, technical skill, communication, and trust. Showing up prepared, staying organized, and making other people’s jobs easier matters more than raw ambition.

Final Thoughts
Lighting is one of the most demanding departments on set — physically, technically, and mentally.
When the lighting department is doing its job well, no one notices. When it isn’t, everything slows down. Understanding how the department is structured — and where you fit into it — is the first step toward working professionally and moving up.
If you’re serious about lighting, learn the hierarchy, respect the workflow, and focus on making the department run better than you found it.
