Since the Great East Japan Earthquake, awareness of energy conservation has increased significantly, and LEDs have become widely adopted as lighting sources due to their long lifespan and low power consumption.
The efficiency with which electrical energy is converted into visible light is known as luminous efficacy. While conventional incandescent and fluorescent lamps typically achieve a luminous efficacy of approximately 10–20%, LEDs have improved this to around 30–50%. High-intensity LEDs are designed to further maximize this efficiency, minimizing energy loss during conversion.
Thanks to their very low power consumption and highly efficient conversion of electrical energy into visible light with minimal heat generation, high-intensity LEDs are capable of producing exceptionally powerful illumination.

Our searchlight delivers an outstanding luminous intensity of 3.1 million candela. To put this into perspective, Cape Muroto Lighthouse in Kochi Prefecture — widely recognized as one of the brightest lighthouses in Japan in terms of both intensity and range — has a luminous intensity of 1.6 million candela. For a more everyday comparison, vehicle high-beam headlights, which are required to exceed 15,000 candela for regulatory compliance, are significantly lower in intensity.
These figures highlight the exceptionally high brightness of our searchlight.
Furthermore, a strobe/flash mode is available, making the searchlight suitable for emergency rescue signaling as well as attention-attracting or disorientation applications.

According to research findings, vehicles equipped with LED stop lamps have been shown to reduce braking distance for following vehicles, thanks to the faster illumination response of LEDs.
Similarly, our searchlight reaches maximum brightness immediately upon activation, enabling rapid target acquisition. This instant start-up performance is one of the key advantages of high-intensity LED technology.

As shown in the graph on the left, a key feature of our searchlight is that illuminance remains nearly constant even when operating on the built-in battery. This is achieved by eliminating any correlation between battery charge level and illuminance through LED driver control.
We are confident that the powerful illumination of our searchlight will contribute to the success of your project.

In general, high-brightness lights tend to shorten the lifespan of their light sources due to lower energy conversion efficiency (luminous efficacy = luminous flux / power [lm/W]). As a result, overall costs may increase due to more frequent repairs and replacements.

Our searchlight, however, features an extended light source lifespan — and therefore a longer product lifespan — making it an excellent choice in terms of life cycle cost balance.

Life cycle balance refers to the overall balance of labor and costs associated with maintenance, repair, and replacement throughout the entire product lifecycle, from purchase to end of life.

Unlike HID lamps, LEDs emit virtually no ultraviolet or infrared radiation, significantly reducing the thermal and radiative load on illuminated objects. In addition, most HID lamps contain mercury, which raises environmental concerns in the event of damage or disposal.

Furthermore, thanks to the advanced thermal management described below, our high-intensity LEDs generate minimal heat, enabling safe operation with a very low risk of heat-related injury.

In cold regions, heat emitted from HID headlights is known to melt snow around the light fixture. In general, higher brightness results in greater electrical energy conversion and, consequently, increased heat generation as a byproduct. For this reason, overheat protection functions are typically incorporated into high-brightness lighting systems.
When a large amount of heat is generated, the overheat protection function may be activated shortly after startup, potentially limiting continuous operation for the expected duration.
Our searchlight features an efficient thermal design that suppresses excessive heat buildup, minimizing the likelihood of overheat protection activation during normal operation.

As mentioned previously, high-brightness lighting systems generate significant heat, and some products require a cooling period before they can be used again. The time required before a light can be activated again is referred to as recycle time.
While HID lamps are valued for their high luminous flux, they operate on a principle similar to that of fluorescent lamps. Depending on the type, HID lamps may require a considerable amount of time to restart after being switched off.
Our searchlight, by contrast, can be reactivated immediately after use, with no recycle time required.

As described above, the advanced thermal management of our high-intensity LEDs significantly delays the activation of the overheat protection function while effectively eliminating recycle time.
As a result, heat buildup within the unit is minimized, and battery consumption is reduced, leading to improved energy efficiency. These factors also reduce stress on internal components, contributing to a longer light source and overall product lifespan.

In the IP67 rating, the first digit indicates the level of dust protection (0–6), while the second digit indicates the level of water protection (0–8). A water protection rating of “7” indicates protection against water ingress even when temporarily submerged under specified pressure and time conditions. A dust protection rating of “6” is the highest level, indicating complete protection against dust ingress.
Our searchlight undergoes rigorous waterproof and dustproof testing to verify its protective performance against harsh environmental conditions such as severe weather and dust. This makes it suitable for reliable operation in demanding environments, including deserts and rainforests.

Based on high- and low-temperature environmental testing, our searchlight is rated for safe operation within a temperature range of −20°C to +55°C.

Our searchlight performs reliably in cold regions, rainforests, and desert environments, as luminous flux is maintained with minimal attenuation even at low temperatures.

The Republic of Mali has a tropical savanna climate with an average temperature of 27.8°C, characterized by distinct wet and dry seasons and significant seasonal temperature variation. The Republic of Djibouti has a desert climate with an even higher average temperature of around 36°C, with summer daytime temperatures frequently exceeding 40°C. Although rainfall is scarce, its coastal location results in an average humidity of approximately 67%, creating a relatively humid desert environment.
In addition, neither country features road infrastructure that is exclusively flat and paved. Resistance to vibration in rough terrain is therefore one of the key advantages of LED light sources.
Our searchlight has demonstrated its performance in these demanding environments, and has been deployed alongside both domestic and international units.

Drops and impacts during transportation and use are among the most common causes of product failure and damage.
For reference, laptop computers are typically subjected to drop tests from a height slightly higher than that of a standard office desk.
Similarly, our searchlight has been tested for drops from a height of 1 meter, reflecting a realistic carrying height, and has been confirmed to remain operational after impact.

The image on the left was taken in a dark room, with our searchlight (right) and a competitor’s light (left) both directed at a white wall. It demonstrates that our searchlight produces uniform illumination with no unevenness.
This is a phenomenon known as illuminance non-uniformity. Illuminance is a physical quantity representing the brightness of light falling on a surface, and is expressed in lux (lx), a unit commonly used for indoor lighting equipment.
In general, in indoor lighting applications, a lower level of illuminance non-uniformity is considered to provide a more comfortable visual environment.

How does the presence or absence of illuminance non-uniformity, as described above, affect real-world searchlight performance?
The image on the left was taken outdoors at night, with our searchlight (right) and a competitor’s light (left) both directed at a forested area. It illustrates how illuminance non-uniformity can significantly affect the visibility of illuminated objects.
As shown, our searchlight enables accurate and detailed recognition of the target.

A portable, high-powered searchlight must also deliver reliable long-range performance.
The image on the left was taken from the opposite shore of a lake, at a distance of approximately 1.5 km.

Simply reaching long distances is not sufficient—the light must also provide practical levels of brightness at that range.

Our searchlight maintains sufficient illuminance at a distance of approximately 1.5 km to allow newspaper text to be read.

In nighttime or low-light search and rescue operations, there are often cases where large floodlights cannot access the site, or where vehicle-mounted units are limited by a fixed illumination range.

Our searchlight addresses these operational challenges. From long-range searches over open water and rivers to the narrowest gaps in collapsed structures, it ensures that essential light reaches exactly where it is needed.

“Delivering the power of a fixed floodlight in a portable form.” This is a key strength of our searchlight, supporting both mobility and safety in frontline operations.

Our searchlight enables early detection of suspicious persons or objects approaching a gate, allowing security personnel to intervene while maintaining a safe distance.
Furthermore, bases and industrial facilities often cover vast areas with numerous structures, making comprehensive patrol coverage both time-consuming and resource-intensive.
By directing the powerful beam of our searchlight toward elevated areas, distant locations, or high ceilings within a facility, security personnel can conduct efficient visual monitoring and inspection as part of their regular patrol routine.

Fires do not always occur on land. When conducting firefighting operations for vessels on open water or rivers, illuminating the scene from shore using vehicle-mounted floodlights has significant limitations, and boat-mounted units may lack the flexibility required for effective response.

Furthermore, even in land-based incidents such as fires at petrochemical complexes, the severity of the situation may make it impossible to approach the site.

With its long-range capability, our searchlight enables personnel to illuminate the scene and assess conditions while maintaining a safe level of distance.

As an island nation, Japan is surrounded by sea on all sides, and in recent years, irregular maritime vessel activity has been observed with increasing frequency. While sensor and camera systems can enhance surveillance on land, the extensive and highly diverse coastline of Japan — combined with the need to monitor not only the surface but also subsurface areas — presents unique challenges for coastal security.
In this environment, coast guard personnel are required to carry out a wide range of operations, including counter-smuggling, anti-poaching, illegal entry prevention, vessel traffic monitoring, and search and rescue operations following maritime incidents.
When suspicious targets are identified, our searchlight enables personnel to maintain continuous visual surveillance while keeping a safe distance.

In recent years, incidents involving unauthorized UAV activity have been increasing. Our searchlight can be utilized as a countermeasure against UAV-related threats such as airspace violations and covert surveillance, enabling long-range detection of UAVs and reducing their ability to capture usable imagery through high-intensity illumination.

Equipped with both steady and strobe modes, our searchlights provide enhanced operational capability in security applications. The high-intensity flashing light can serve as a visual warning and attention-attracting signal in security situations, helping personnel manage and respond to incidents more effectively.

By using a sling and holding the searchlight like a gun, the design makes it easy to aim and adjust the irradiation angle even if there is a distance from the target.

A lens guard is attached to the front to prevent the lens from cracking and to prevent the lens from dropping during use.

By using Picatinny rails, you can customize what you need for your searchlights. It is possible to have versatility.

The searchlight with built-in battery integrated into a single unit for easy handling and excellent portability. In addition, handles and other items are attached to make it easy to grasp and carry.
