Floodlight

You need light for an entire hall or a large studio interior — and you need it quickly and evenly. That's exactly when you reach for the floodlight. It's the workhorse fixture on set: wide-beaming, with little ability to focus, providing maximum light output over a large area. Where a Fresnel or an ellipsoidal spotlight precisely shapes a beam of light, a floodlight simply throws its light into the space — covering it extensively.

In practice, it works like this: You hang floodlights in rows — at the top of the hall, on the walls, from the front. The reflector is flat or slightly curved, with the lamp sitting deep within it. The light spreads forward and to the sides without you having to fiddle with shutters or focus rings. For large productions — sports broadcasts, factory scenes, hangar shots — floodlights are your base setup. They create a flat, even brightness that casts no shadows, or only very soft ones. This isn't always aesthetically interesting, which is why floodlights are usually used as key lighting and combined with directional fixtures — spots for contours, Fresnels for drama.

The disadvantages are obvious: no creative control, no shadow modeling, a lot of spill into corners and onto unwanted surfaces. In the studio, this is exacerbated — you lose a lot of light that you don't need at all. On exterior sets or industrial locations, where evenness is important, floodlights play to their strengths. Also for live shoots in large spaces where time is precious: you hang up floodlights, turn them on, and you're done.

Technically, floodlights are robust — usually with high wattages (1500 to 5000 watts and more), with thick bulbs or, more recently, LED variants. They get hot and need space for ventilation. For interface lighting (where continuous, hard illumination is crucial) or as fill light on set, they remain a classic — precisely because they are undemanding and function reliably.
