XeVision LED Aircraft Lights: Superior Performance

Illuminate Your Skies: Why XeVision LED Aircraft Lights Lead the Way

When it comes to the safety and efficiency of your aircraft, the quality of your external lighting is paramount. XeVision, a name synonymous with innovation in aviation lighting, offers a revolutionary line of LED landing and taxi lights designed to set new industry benchmarks. Their XeTREME™ series, featuring the XV36-LED-7UN landing light and XV36-LED-7EL taxi light, represents a significant leap forward in performance, reliability, and advanced technology. This article delves into why choosing XeVision LED aircraft external lights is a decision that prioritises superior visibility, long-term value, and uncompromised safety.

Unleashing the Power of XeTREME™: A New Era in Aircraft Lighting

XeVision's XeTREME™ range is engineered to deliver an unparalleled lighting experience for pilots. These aren't just lights; they are sophisticated illumination systems designed to enhance situational awareness in all conditions. The core of this innovation lies in XeVision's proprietary active cooling design, which ensures that the lights operate at peak performance without suffering from the dreaded thermal degradation that plagues many competitor products. This means sustained brightness and longevity, even under demanding operational cycles.

The XeTREME™ Advantage: Outshining the Competition

The performance metrics of XeVision's LED landing and taxi lights speak for themselves, placing them significantly ahead of the competition. Let's break down the key advantages:

• Unrivalled Centre Brightness: The XeTREME™ par-36 type LED landing light boasts a centre brightness that is more than double that of its competitors. This intense focal point is crucial for piercing through adverse weather conditions and providing clear visibility during critical phases of flight.
• Exceptional Beam Intensity: Even at a narrow beam angle of 9º, XeVision's luminous intensity surpasses the centre beam brightness of many competing lights. This focused power ensures that light is directed precisely where it's needed most, minimising light spillage and maximising effective illumination.
• No Thermal Degradation: Unlike many LED lights that experience a noticeable drop in brightness as they heat up, XeVision's lights maintain over 96% of their brightness over time, thanks to their highly efficient proprietary cooling design. This consistent performance is vital for predictable and reliable operation.

Spotlight on the XeTREME™ Series: Landing and Taxi Lights

XeVision offers two primary models within the XeTREME™ series, each meticulously designed for its specific role:

1. XeTREME™ XV36-LED-7UN LED Landing Light

This is the flagship of XeVision's landing light technology. Designed to replace traditional PAR 36 lamps, the XV36-LED-7UN delivers an astonishing luminous intensity of 322,000 candela (cd) with an input power of just 100 watts. Its focused 9º beam angle provides an impressive range of over 800 meters (half a mile) at 0.5 LUX. The light also features a wider 15º field angle, ensuring a comprehensive view of the approach path. Encased in high-transmission, hardened, anti-reflective glass, and featuring a proprietary microprocessor-controlled active cooling system, this landing light is built for endurance and peak operational efficiency.

2. XeTREME™ XV36-LED-7EL LED Taxi Light

Complementing the landing light, the XV36-LED-7EL taxi light provides exceptional ground illumination. With a rectangular beam pattern, it offers a broad 34º horizontal beam angle and an 11º vertical beam angle. This design ensures excellent coverage of the taxiway, illuminating not only the path directly ahead but also the sides of the aircraft. While its luminous intensity is rated at 55,125 cd, its wide beam pattern is ideal for ground navigation, significantly enhancing safety during taxiing. Like its landing light counterpart, it benefits from the same advanced cooling, microprocessor control, and robust construction, making it a dependable choice for ground operations.

Advanced Features for Enhanced Safety and Control

Beyond raw performance, XeVision's lights are packed with features that enhance usability and safety:

• Three Cockpit Controllable Light Patterns: Both the landing and taxi lights offer three distinct modes: HIGH (100% brightness), STROBE (XeStrobe™), and LOW (50% brightness). These modes are easily cycled through using a standard cockpit toggle or rocker switch, offering flexibility for different flight and ground conditions.
• XeStrobe™ Technology: XeVision's proprietary strobe mode is designed for maximum visibility and recognition, serving as a crucial safety feature to mitigate potential bird strikes during critical flight phases.
• Microprocessor Control: The integrated microprocessor manages brightness, thermal regulation, and safety circuits, ensuring optimal performance and longevity. This intelligent control system also provides redundancy through three independent LED string drivers.
• Robust Construction and Environmental Resistance: Built with aircraft-grade aluminium (6061-T6) and featuring toughened glass lenses with AR coating, these lights are engineered to withstand the rigours of aviation. They are also nitrogen-flushed to prevent fogging and boast an IP65 ingress protection rating, making them resistant to water and dust.
• EMI/RFI Certification: XeVision lights are certified to DO-160G standards for Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI), ensuring they do not disrupt other aircraft systems.
• Repairability: Designed with future-proofing in mind, all modules are 100% repairable, contributing to a lower total cost of ownership over the lifespan of the product.

Understanding Light Measurement: Candela, Lux, and Lumens

To truly appreciate the performance of these lights, it's helpful to understand how aircraft lighting is measured:

• Candela (cd): This unit measures luminous intensity, essentially the brightness in a specific direction. For landing lights, high candela is critical for projecting a powerful beam over long distances.
• Lumens (lm): This measures the total amount of visible light emitted by a source. While important for overall brightness, it doesn't indicate how focused the light is.
• Lux (lx): This measures illuminance, the amount of light falling on a surface. It's often used to define visibility range (e.g., 0.5 lux at 800m).

XeVision's photometric evaluations are conducted by independent, certified laboratories following strict IESNA:LM-79-08 test procedures. This rigorous testing ensures the accuracy and reliability of the reported performance data, providing pilots with trusted specifications.
