Energy Efficient Scene Lights
Scene lights are great for nighttime road projects, security checkpoints and emergency situations like accident and crime scenes. They also come in handy as backup lighting for EMS professionals, fire crews or railway engineers working during the night.
They don’t need a generator and are completely silent to reduce stress on responders in chaotic situations. They’re also cordless, so there’s no danger of tripping on a long cord.
Brightness (or luminous flux) is the amount of light that a particular light source produces. This is typically expressed in lumens, but illuminance can also be used.
A luminous source can produce different levels of brightness depending on how it is controlled. For example, a spotlight can have a higher intensity when it is mounted on a tripod and lower when it is fixed in place. This is because the beam of light is shaped differently from a traditional bulb or lamp, which allows it to illuminate the scene more effectively.
Lighting can also be controlled with the use of a diffuser, which reduces the direct impact of the light on the scene. This is especially useful for photographers who need to make use of soft lighting, as it reduces the contrast of the lights.
Another important factor is the color temperature of the light source. Generally, the higher the Kelvin value, the whiter the light. Using the light temperature in conjunction with the power input to determine brightness is an effective way of ensuring that you are getting what you need.
In addition, it is worth noting that light sources such as LEDs require up to 95% less energy than their predecessors to produce a similar level of brightness. This means that luminous flux is no longer the most accurate way of describing light output.
As such, luminous intensity, measured in candelas (lm/sr) is the better choice for describing the brightest light available, as it is more accurately representative of the true luminosity of the light source. However, this is not necessarily an objective photometric measurement as it may also depend on the type of light and its position in the beam.
Finally, it should be noted that the best light sources are not the brightest on the market. For example, a halogen bulb is far more efficient than a conventional bulb, but it does not have as much luminous intensity, or brightness.
For this reason, the best light is often a combination of both types of lighting. This is especially true if you are trying to illuminate a space with a large number of lights. For this reason, it is best to create a lighting plan before beginning your shoot. This will allow you to determine how to get the most out of your lights in terms of brightness, while maintaining the integrity of the rest of your lighting plan as well.
Color Rendering Index
When looking for the perfect scene lights for your home or business, you may have come across the term “color rendering index” (CRI). It’s important to understand what this means and how it can affect your lighting project.
CRI is a measurement of how well an LED light source shows colors accurately. Typically, the better a light source is at showing the color of an object, the higher its CRI. This is why LED lighting products with a high CRI rating are often better suited for residential applications than lower-grade ones.
The CRI of a light source is measured against the CRI of a reference source, such as natural sunlight. The closer the light source is to natural sunlight, the better it will show colors. This is why LED lamps with a high CRI are considered more “natural” than low-CRI ones.
Most lighting products are tested for their color rendering index using a set of reference colors that represent the full range of colors. The test takes place in a laboratory and uses equipment designed to measure the amount of light that is absorbed and then converted to different colors, such as red, blue, green, yellow and white.
In the world of color rendering, the highest value is defined as a CRI of 100, which indicates that a light source produces colors exactly as nature does. This is why incandescent and halogen bulbs have a CRI of 100, even though they generate heat to produce the light.
However, a light source that is too bright or too dim will negatively impact the way you see and experience colors. This is especially true in residential areas where it can significantly alter the appearance of furniture, artwork and other items on display.
Fortunately, the light industry has come up with a way to ensure that LEDs will display colors in a more accurate manner. This is called the Color Rendering Index, which can scene lights be found on the product packaging of LED light bulbs and fixtures.
For most lighting projects, 80 CRI is the benchmark. But for more complex applications such as commercial, retail, art galleries and stage / studio applications, a higher CRI is recommended. This will ensure that colors appear as they should, are accurately rendered and look crisper and more vibrant.
Lighting accounts for approximately 9% of an average home’s electricity use – coming fourth after heating/cooling your home, water heating and domestic appliances – so ensuring energy-efficient lighting is one of the most effective ways to lower energy bills. Similarly, transitioning to connected LED lighting can save up to 85% of energy.
When selecting new products for your lighting systems, it is essential to evaluate their energy efficiency in a way that makes sense for your particular application and your budget. This is especially important when comparing lights that operate on different power levels or in different locations.
The most common measurement of lighting efficiency is luminous efficacy (Lm/W), which measures the amount of visible light produced per watt of power used. The higher the value, the more efficient the bulb is.
While choosing new lamps, make sure that they are energy efficient and comply with all energy efficiency standards. For example, choose a lamp that is certified to meet the requirements of Energy Star and other prestigious energy-efficiency programs.
For instance, the Queens Museum in New York City replaced their old halogen lights with a modern LED track light and control system to cut their energy costs by 90 percent. By reducing their energy consumption, the museum has become more sustainable and is better equipped to help the planet.
Choosing an energy-efficient lamp is the first step to making your lights more sustainable. Then, install controls that allow for intelligent dimming, automated shut-offs and other features that can cut your power consumption even further.

Scene lighting is essential for safety on the fire ground, especially when responding to structure fires. A properly lighted fire ground reduces the potential for secondary incidents and allows firefighters to work more efficiently.
A dependable, bright light is needed to see through the smoke and debris and find what is inside a building. It also allows firefighters to move around the scene more effectively and prevents them from getting trapped by darkness.
For this reason, firefighters need scene lights that are easy to carry and have great durability. They also need to be able to adjust the beam so they can switch from floodlight mode for long range searching and spot mode for immediate task lighting.
These lights can also be adjusted to be waterproof and height adjustable, allowing them to be mounted in challenging locations that would be difficult to access with standard personal lighting options. Waterproof lights are particularly helpful when working in areas where a vehicle may be partially submerged.
The height of scene lights should be at least 8′ to allow the light to be raised above alley walls, bushes, vehicles and people in a way that is safe. Choosing a light that is too low can create shadows on the sides of the apparatus, which is not acceptable.
One of the most common road and highway incidents involving emergency responders is hitting a motor vehicle that is in the path of a responding unit. This is why roadway scene lights have become so important to emergency responders.
According to the Emergency Responder Safety Institute, 65 emergency responders were struck and killed while operating at roadway incidents in 2021. As a result, emergency responders are more aware of their surrounding environment than ever before.
In addition to providing safe illumination, scene lights are often used to help establish a safety zone. They also help alert approaching motorists to the presence of an emergency by directing their attention away from the road.
In addition, they can be used to warn drivers of hazards such as downed trees and obstructed highways. It’s important to keep in mind that a higher level of visual light intensity can increase the risk of collisions for both motorists and emergency personnel.
