XeVision® XeTREME™ LED LANDING LIGHT (par-36/46)
MFR Model# XV36-LED-7UN
Overview
|
The XeTREME series is a true game-changer in aviation high-intensity LED for BOTH landing and taxi light performance.
By out-of-the-box thinking, XeVision has achieved efficient and dependable extreme brightness for LED "light engines", with certified and published Lab measured outputs greatly exceeding anything currently on the world market (see above, the documented performance comparison graph photo). High-power LEDs inherently generate a lot of heat while in operation. The excess heat needs to be dissipated quickly, otherwise, the system may suffer a possible thermal run-away which dramatically lowers the LED output, and lowers the LED lifespan, which in the worst case may even destroy the LED. Common solutions for LED lights are implementing passive heatsinks to address this adverse effect, however, usually not efficient enough. To avoid damage to the LEDs in those LED lights, the power to the LEDs is reduced by an electronic safety circuit with the negative result of significantly reduced brightness. In contrast, XeVision® opted for a very effective Active Cooling approach. XeVision's proprietary active cooling design guarantees sustained highest light output and long component life by a meticulously designed cooling concept starting at the LED to substrate level, selecting low thermal resistance materials and TIM (Thermal Interface Material), and ending with a fan supporting pin fin heatsink very efficiently dissipating heat to the ambient air. For the advanced high-efficiency design concept, XeVision selected state-of-the-art high-power LED chips and optimized TIR optics together with a protective high visible light transmission hardened AR (anti-reflective) glass. After several years of development and extensive testing, we established that the light fixtures were producing more than 96% of brightness even after days of continuous operation under ambient conditions, around 25ºC. Fixture and heatsink temperatures stayed well below 60ºC thanks to our proprietary no-compromise active cooling design for the LED light engine including the supporting control electronics. The XV36-LED-7UN LED landing light is an extreme powerhouse in regards to luminous intensity and a benchmark for a lamp with a par 36 form factor generating > 320'000 cd (Candela / Candle Power) of light at 100 W power input, more than double what the closest competitors currently claim for initial output. The landing light easily reaches 800 m (1/2 mile) of range at a comfortable 9.5 degree primary beam angle, 15+ degrees useful Field Angle. The visible areas are quite uniformly illuminated allowing excellent clarity of view. The size and range of the beam pattern are a good match for both fast and slow landing aircraft. This landing light beam is also quite effective for taxing purposes. The light’s High intensity XeTREME power provides a great enhancement for "See and be seen" during all phases of flight. XeVision's proprietary strobe mode, dubbed XeStrobe™, is purposely designed by their engineers for better recognition. The XeStrobe™ pattern and high brightness light beam of this LED landing light is a perfect solution to mitigate bird strikes. Used together with the LED taxi light version, the wider taxi projecting angle helps to reach flocks of birds over a wider range. By using both Landing and Taxi fixtures with the XeStrobe™ pattern selected “To be seen” is a no-brainer even for birds. XeStrobe™ is far superior to the traditional wig-wag pattern. |

Reviews
Love this Landing Light. The Install in our PA28 was fairly simple. Light looks great and is amazing at night. Will also be installing in our PA32 very soon. The most amazing part of this product is the customer service from the manufacturer.
We installed this light to enable better visibility when landing at night. It works extremely well, can easily see all the way to the end of 3000+ ft grass runways when landing at night. This light is brighter than any LED and HID landing lights we have previously used. The light maintains consistently extreme bright light output even when left on continuously for 3+ hours. Highly recommended if you want the best possible runway visibility during night landings. The light also provides a great daytime flying risk mitigator with a unique strobe mode which can reduce the the risk of bird strikes.
I think I was the first to buy a set from Spruce when I first saw the add pop up. I have installed them and they are no doubt the brightest most powerful light available for GA. A little heavy compared to just plug and play new bulb technology but the power these have if phenomenal. I have had trouble seeing the taxiway turn offs at airports an night, that is no longer an issue. They draw about 7 amps each on my 12 volt airplane, in landing mode (brightest).

Please note, Aircraft Spruce Australia's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce Australia assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.
This light is currently non FAA approved. Any install in a certified aircraft would need to receive a form 337 field approval. The manufacturer is seeking FAA STC approval for these lights.
That depends on the system nominal voltage, 14 or 28 VDC. @14 VDC input: 7.5 to 7.75 amps for High, strobe ~ 2 amps (avg), Low 4.25 amps | @28 VDC input: 3.75 amps for High, strobe < 1 amp (avg), Low 2.25 amps. Full power mode is about 105 total watts at any voltage from about 12 to 32 VDC.
For the actual Landing Light version, "XeVision -7UN" model, the primary beam width of 9.5 degrees (Certified optical Lab proven sustained Center beam Candela of 320,000+ Cd) see the comparison graph with the photos. Beyond the primary beam 9.5 degree edge (typically only needed for Taxiing), output is still 150, 000 to 160,000 Cd - Candela / (Candle-power) and reducing gradually from there out to and well beyond 15+ degrees. The "-7UN" landing light version being used for taxiing (depending on conditions) offers more than 15 degrees (secondary beam angle) of useful illumination but realistically not more than about 20 degrees. The XeVision LED landing light offers plenty of light at 15+ degrees beam width offering very effective taxiing performance as well.
No need for a compromised "all in one" - dual Landing/taxi light currently being offered by some, optimized for neither landing nor taxiing. The others and very best performing competitors only provide about 150,000 Cd at their beam center, ie. peak output (Candela). However, after being on for only 5-10 minutes their outputs are ALL reduced by about 50% (1/2). If their LED light is also located in the hot engine compartment, its already having a significantly decreased output when first powered, due to their heat controlled brightness throttling from ambient high heat exposed engine compartment temps. Note: a GE 4509 incandescent bulb beam angle is 12 degrees wide X 8 degrees tall and quite dim by any and all comparisons, claimed center beam 110,000 CP or Candela.
The Landing light "-7UN" version offers a circular and uniformly round beam pattern so there is no "up" orientation to follow for the Landing version "-7UN" lights. Because of this the power connector can be oriented (rotated) in any position (360 degrees) desired for clearance or other reasons / preferences.
