The Importance of Scene Lights for First Responders

The Importance of Scene Lights for First Responders

A scene light is a handheld, portable lighting tool that can illuminate a large area of a scene or building. These lights are essential for firefighters, emergency responders, and other professionals working in dynamic scenarios that require fast, hands-free illumination.

These lights are also perfect for hazmat workers, road construction, railway engineers and other professional users who require lightweight, easily transportable lighting tools. They offer a variety of features, including beam adjustability and are battery operated.


Scene lights provide a variety of benefits for first responders. They are fast to deploy, require no cords, are easy to move and eliminate trip hazards. In addition, they are silent and don’t require a generator to operate. These features can be especially important when a responder is in a noisy and chaotic situation.

LEDs are more efficient than halogens and consume less power to produce the same amount of light. This means that if your department has 500 watts available on a vehicle for scene lighting, two LED scene lights can deliver 40,000 lumens of light, almost four times the output of a single halogen light.

Efficient and bright, LEDs have a longer runtime than traditional halogens. These benefits can be particularly useful for fire departments requiring multiple lights to light a large area.

Portable scene lights are battery powered, which allows them to be moved and positioned without restrictive cords connected to trucks or generators for power. They can also be used in remote areas where truck scene lights cannot reach.

They are quick to set up, allowing one person to stage them around an incident in 2-5 minutes. They can also be repositioned if the conditions of an incident change.

Beam adjustability is another important feature of scene lights. This allows a responder to switch between spot mode for long range search and area setting for immediate task lighting.

The flood and spotlight modes can also be manipulated to provide maximum versatility in a variety of situations. Whether it’s illuminating alleys and the back of buildings, or helping drone overwatchers to see nighttime elements that their thermal cameras can’t, this versatile design is sure to meet your needs.

Safety is an important consideration for any first responder, and portable lights are especially effective in reducing the risk of injury. A cord running across a walkway is an invitation for someone to catch it and fall.

Portable scene lights are also a good option for command posts and Battalion cars. These lights can be used to illuminate Chief’s equipment, tools and radios without taking up valuable storage space within the Command vehicle or Battalion car.


Intensity is the amount of light that a scene light outputs, typically measured in lumens or footcandles. Typical stage lighting illuminance may vary from 25 to 200 footcandles, or more.

Intensities can vary based on what is being illuminated, from one part of the frame to another, and even from subject to subject. For example, when lighting an actor, it is generally recommended to have a 4-to-1 ratio of light on the left side of their face in relation to the right, and for fill lights, a 3-to-1 ratio of light on the subject’s face in relation to the background.

This is also important in creating a consistent look and feel for actors as they move from one area light to the next. If the intensity of each light in the rig is different from the next, then the actors’ movement will be difficult to follow and their cues will not have the desired effect.

To control the scene lights intensity of a scene light, there are several properties in Maya that you can use. These include:

AttenuationCutoff: If set to (min, max) this feature will enforce a specific distance over which the intensity is scaled linearly down to 0. This is useful for making certain effects that aren’t easily controlled with other attributes.

ProjectedCubemap: If set to a valid cubemap this texture is projected onto the light’s surrounding geometry. This can be used for a variety of interesting effects and is particularly effective in conjunction with the occlusion shader.

Specular Light Intensity Multiplier: This is a generalized property that can be used for artistic control over the intensity of specular reflections on surfaces like metals or mirrors. Setting this value to 0 will make the light object disappear from these specular reflections, while keeping it at 1.0 will give photo-realistic results.

Intensity can also be used to define a threshold for a light that will cut off its intensity when an object is beyond the defined threshold. The default value is a meter. The higher the value, the softer and more gradual the transition of the light will be.


The direction of your scene lights can have a significant impact on the look and feel of your scene. It can help you create depth, shape, and pop your actors out from the background. In addition, the direction of your lights can influence how you play with shadows to tell a story.

The main directional light API is designed to simulate the main lighting source in your scene, allowing virtual objects to show reasonably positioned specular highlights and to cast realistic shadows. In addition, ARCore provides spherical harmonics to help simulate reflections in shiny metallic objects.

While this spherical lighting effect is not particularly spectacular, it can provide subtle cues to scene lights the viewer about how the virtual objects in your scene are defined and what they look like.

You can adjust the color and intensity of your main directional light, and you can even add a spherical texture to it to simulate reflections in shiny metal. You can use these effects in conjunction with your main directional light to create an even more impressive ambiance and increase the quality of your lighting.

For this reason, it is important to consider the direction of your scene lights when selecting a suitable light type for your scene. The direction of your scene lights can be influenced by your camera angle, the position of your actor in relation to your lighting and the position of your object in relation to the light source.

Generally, you should aim for light sources that are close to your subject. This will improve performance and reduce the number of light sources you need to use, which can lead to better quality.

Aside from the main directional light, you can also use ambient lights to brighten up your scene and give it some flair. These lights, which are based on the base Light class, affect all objects in the scene and can be used to illuminate the environment around your characters and the scenery that they will walk on.

The most important thing to remember is that if you want to use ambient lights, you should only use them if they are the most effective lighting for your scene. Otherwise, you may find that your scene looks flat and uninteresting.


Soft light is a style of lighting that has many uses in filmmaking. It can be used to create beauty shots, add depth and character to characters, and even help the audience connect with them.

Unlike hard lighting, which produces strong shadows and harsh edges, soft light casts subtle shadows that are very flattering to human subjects. This type of lighting also helps to minimize the appearance of wrinkles and blemishes on a subject’s face.

To achieve this look, you can use a diffuser or other diffusion materials to disperse the light around the subject. Alternatively, you can use reflectors to bounce the light back into the scene and produce smoother shadows.

This is a relatively easy style of lighting to accomplish, especially for those on a budget. However, it does require a lot of additional tools to control its spread. In addition to grids and egg crates, you may want to consider using barn doors or snoots to restrict the light’s spread.

A soft lighting technique is useful for tense scenes, as it can help to convey a sense of calm. For example, the diffused lighting in this scene from the Netflix original series The Dark Crystal: Age of Resistance softens each puppet’s face as they navigate the forest.

The soft light also highlights each character’s sweetness and innocence, helping the audience to relate to them on a deeper level. This is a great way to endear your subject to your audience and keep them watching long after the scene ends.

You can easily achieve this type of lighting by shooting on overcast days. The clouds act like a giant softbox, dispersing the light over a much larger area than the sun’s rays would.

Another way to achieve soft lighting is by setting up a 3-point lighting setup with multiple sources. Using reflectors to bounce the light back into your scene can also give you a very soft look.

Finally, it’s important to remember that soft light tends to fall off a little more quickly than hard light, so you may need to position your source closer to your subject to get the best effect. This is true of any light source, but it’s particularly noticeable with smaller light sources.
