Donato Sasso, Director International Business Development at Streamlight, explains why beam pattern, colour rendering and additional features matter more than ever
For decades, Streamlight has built its reputation on producing lighting solutions trusted by professionals who work in the most demanding environments.
While consumer markets often focus on sheer brightness, fire and rescue professionals require much more than raw output.
Reliability, accuracy, and safety are non-negotiable features when lives are at stake.
To explore how innovations in beam pattern, colour rendering, certification, and power flexibility are reshaping lighting technology for emergency services, International Fire and Safety Journal sat down with Donato Sasso of Streamlight.
In this wide-ranging discussion, he explains why effective visibility depends on more than lumens, and how future developments will continue to support firefighters, rescue workers, and inspectors in the most challenging conditions.
Color-Rite® technology improves colour rendering. Why is accurate colour perception so critical in fire, rescue, or inspection scenarios?
In fire, rescue, or inspection scenarios, accurate colour perception is more a matter of safety than convenience.
For a firefighter, this can mean correctly identifying the colour of a wire or fluid and reducing mistakes.
If you misjudge a wire colour in an electrical panel, for example, you can create an immediate hazard.
If you mistake one fluid for another in a spill situation, you could expose yourself and others to additional danger.
Conventional lighting can distort or wash out colours, particularly in smoke-filled or poorly lit environments.
That distortion might not matter in everyday use, but for professionals, it can be the difference between a safe outcome and a life-threatening error.
Color-Rite® technology is designed to give firefighters and inspectors confidence that what they see is what is really there.
When you are under pressure, working in an unstable environment, there is no time to second-guess whether you are looking at the right thing.
Accurate colour perception allows you to make quick, informed decisions, which ultimately keeps both responders and the public safer.
How do Streamlight’s beam patterns help firefighters and rescuers handle different visibility challenges in the field?
The beam pattern determines how useful a light actually is in the field.
Wide flood beams provide broad area illumination, which is ideal for situations like lighting a smoke-filled room, searching a collapsed structure, or managing an accident scene.
These scenarios demand the ability to see as much of your surroundings as possible so you can identify hazards and locate people who may need assistance.
By contrast, high-candela spot beams are designed to cut through smoke, fog, or total darkness and provide long-range visibility.
They provide firefighters and rescuers the ability to pinpoint hazards or victims at a distance.
It might be the difference between spotting a trapped person at the far end of a corridor or identifying a risk on a roadway before you reach it.
Having access to both types of beams means that first responders can adapt to rapidly changing conditions.
A single call-out can involve moving from wide area search to focused long-range work in moments.
Streamlight designs its lights with that flexibility in mind, because in the field, it is not just about how bright a torch is, but how precisely that light is delivered for the job at hand.
Streamlight emphasises safety certifications like ATEX. How do these ratings expand usability for fire and rescue professionals?
Fire and rescue professionals often work in hazardous environments where explosive gases, vapours, or dust may be present.
In those situations, even something as simple as switching on a torch has to be safe.
That is why safety certifications like ATEX are so important.
They prove that the equipment has been rigorously tested and can be relied on in explosive or high-risk atmospheres.
When you are on the ground, you do not have the time to question whether your gear is safe to use.
You need confidence that it will not add risk to an already dangerous environment.
ATEX certification gives that assurance.
It also means that our products are internationally recognised.
Fire and rescue services are increasingly working across borders or in cooperation with other agencies, and having equipment that meets global standards ensures compatibility and trust.
Our focus on certifications is really about enabling professionals to do their jobs without hesitation, knowing that their equipment has been designed for the environments they actually face.
Multi-Fuel technology gives flexibility with batteries. How important is this for first responders working in unpredictable conditions?
In emergencies, conditions are rarely ideal.
Power outlets may be inaccessible, rechargeable batteries may be drained, or the supply of replacements may be disrupted.
Multi-Fuel technology solves this problem by allowing our lights to run on different power sources, whether that is a rechargeable pack, standard alkaline cells, or lithium disposables.
That flexibility is a huge benefit to first responders.
You might start a shift with fully charged batteries, only to find the operation goes on far longer than expected.
Or you may be deployed in an area with no power at all due to a storm or major incident.
In those moments, the ability to switch power sources and keep working is crucial.
It is all about resilience.
Emergencies are unpredictable by nature, and your equipment needs to adapt to that reality.
With multi-fuel, responders do not have to worry about their light failing at the wrong time.
They can keep going with whatever is available, which ensures they always have the visibility they need to carry out their work.
Looking ahead, how do you see Streamlight balancing raw output with smarter features that improve safety, usability, and reliability?
As technology advances, the focus is shifting away from raw output toward smarter, more usable features.
For us, it is about finding the right balance.
High brightness will always be valuable, but the bigger picture is about improving safety, usability, and reliability.
We are looking at innovations like advanced optics that deliver light exactly where it is needed, improved colour rendering technologies that make identification safer, and adaptive power systems that provide greater resilience in the field.
These are not just enhancements for the sake of it.
They are features that make our lights more effective tools for professionals working in life-and-death situations.
The future of lighting in fire and rescue is not about chasing higher lumen numbers.
It is about delivering visibility that is reliable, precise, and purpose-built.
That is what will give first responders the confidence to act decisively in the most challenging environments.
Lighting built for real-world conditions
The conversation with Donato Sasso highlights that visibility in fire and rescue depends on much more than brightness.
Accurate colour perception, adaptive beam patterns, verified safety standards, and flexible power sources all determine whether a light performs effectively in practice.
Streamlight’s focus is on practical reliability rather than headline lumen figures, reflecting how firefighters, inspectors, and rescue teams actually work.
By designing equipment around operational reality rather than specification sheets, the company aims to give professionals tools that maintain safety and performance in every condition.
