The “Best Value King” for Large-Area Illumination – LPE73Z 2000W LED Light

When it comes to high-intensity lighting, many people immediately think about “how far it can reach,” but they often overlook a more common need in real-life scenarios—how to evenly illuminate large spaces like suburban areas, disaster sites, or open-air squares at a reasonable cost. 

This is where the LPE73Z 2000W LED light truly stands out. It is the preferred solution for large-area illumination, balancing both coverage and cost-effectiveness.

The 2000W LED light delivers an impressive luminous flux of 120,000 lumens. At a beam angle of 7 degrees, its central optical intensity reaches 10.2 million candelas. This means that the light can illuminate up to 7,300 meters, producing a circular beam with a diameter of 782 meters and covering an area of 480,000 square meters.

In comparison, A renowned brand’s Searchlight has been widely applied in search and rescue, security, and exploration scenarios. Its beam angle can be adjusted from 1 degree in spot mode to 40 degrees in flood mode.

The Searchlight uses an 85W Xenon Short Arc Lamp as its light source. With a high-precision aspheric reflector, the light is concentrated into a very small solid angle, producing a beam less than 2 meters wide at 1,000 meters.

When focused, the Searchlight achieves a central beam intensity of 12 million candelas, with a maximum range of 6.9 km.

Since the Searchlight uses only a single xenon lamp as its light source, its luminous flux can be estimated at less than 2,900 lumens based on its optical intensity and beam angle.

At a 1-degree focus, the central illuminance at 1,000 meters is 12 lux, extremely bright for night operations, but the beam covers only 18 meters in diameter—an area of just 240 square meters. Expanding the beam to 6 degrees reduces the central intensity to 330,000 candelas and limits the range to less than 1,200 meters

The core advantage of the 2000W LED light lies in its large-area coverage capability. Its design philosophy revolves around “filling large spaces with light.” By combining multiple high-power LED chips with a diffusive optical design, the light is evenly distributed across a wide area.

The 2000W LED light has roughly 24 times the power of the Searchlight, and with more efficient LED chips, it produces a luminous flux of 120,000 lumens—over 40 times that of the Searchlight.

The 2000W LED light features a continuous zoom lens ranging from 7° to 16°, providing a wide illumination range and flexible beam adjustment. At a beam angle of approximately 7°, the light spot at 1,000 meters has a diameter of no less than 122 meters, with an average luminous intensity of 10.2 million candelas and the average illuminance of around 10 lux at that distance. This allows clear visibility over an area of 11,600 square meters, nearly equivalent to the size of two football fields.

In comparison, to achieve the same 10 lux illuminance at 1,000 meters, the Searchlight produces a light spot with a diameter of about 18.8 meters and an area of roughly 280 square meters, approximately the size of three doubles badminton courts.

In other words, one 2000W LED light is equivalent to operating more than 40 Searchlights simultaneously.

In emergency rescue and law enforcement scenarios, just one or a few 2000W LED lights can provide seamless, no-dead-zone baseline illumination, with uniform and stable ground brightness, avoiding local dark spots. Additionally, it offers outstanding cost-effectiveness—one 2000W LED light costs less than several the Searchlights. For large-area illumination, achieving adequate baseline brightness at lower cost is the key requirement.

LEDs also excel in lifespan. With proper heat dissipation, the 2000W LED light chips have an estimated 30,000-hour lifespan—roughly 3.5 years of continuous 8-hour daily use. In contrast, xenon lamps available time achieve to 3,000 hours, requiring replacement over 10 times per year, incurring higher consumable costs and labor-intensive maintenance.

In search and rescue or security operations, the long lifespan of LEDs avoids the risk of lights failing mid-operation, whereas overdue xenon lamps could fail at critical moments, compromising safety.

The key to selecting illumination equipment is matching real operational needs, not chasing extreme specifications. When your goal is to provide stable, cost-effective baseline lighting for emergency rescue and law enforcement, the 2000W LED light is the smart choice—the “right light for the job.”
