LED technology offers numerous advantages over conventional Halogen and Xenon bulb based aircraft lighting technologies. These advantages include:

Long Life
When integrated into a well designed lighting system with adequate heat sinking and solid-state mounting, LED based lighting products will easily last over 50,000 hours of continuous operation. Unlike most other light sources, LEDs do not have their lifespan reduced by on/off cycles. AeroLEDs products are designed to keep the LED junction temperatures well below their maximum rated values to ensure that the manufacturer’s rated life projections are achieved, and all of the LEDs are hard mounted to avoid stress failures. Halogen bulb landing lights typically only last 100 hours, and Xenon strobe tubes typically only last 2000 hours in the aircraft environment.

High Efficiency
The LEDs used in AeroLEDs products have high lumen efficacy ratings, and as a result our products typically use less than 1/3 the power of halogen bulbs. This significantly reduces the electrical load on the airplane’s battery and alternator system. On final approach, low engine RPMs result in a reduced output from the alternator, so halogen bulbs typically brown-out the electrical system and produce less than their rated light output at full voltage. AeroLEDs LED lights maintain their full light output even at lower battery voltages

Shock and Vibration Resistant
The LEDs in our product are solid-state mounted devices that can tolerate high levels of shock and vibration without failing. The primary driver of Halogen bulb filament failures and Xenon tube lead failures is airframe vibration. Our LED lights are designed to tolerate this high vibration environment indefinitely.

Less Weight
Our LED strobe products utilize built-in power supplies and are very lightweight. Traditional Xenon strobes utilize large, heavy power supply boxes. Converting to a pair of AeroLEDs wingtip strobes can remove 3 pounds of weight from an airplane.

Low Drag
Our LED strobe products are streamlined designs that take advantage of the small size of LED light sources to create an aerodynamic profile that produces less drag than traditional Xenon strobe housings.

Built-in Pulse Mode and Synchronization
All of our landing light products have a built-in pulse mode that blinks the light on and off at a 1Hz rate when power is applied to the pulse mode power wire. All of our landing light products and synchronize with each other regardless of model to create a wig-wag alternating flashing pattern for enhanced in flight visibility for air to air and air to ground collision avoidance and recognition.
All of our strobes have a synchronization signal that can allow them to flash in unison when connected together.

Higher Color Temperature White
Our lights use 6500K (sunlight equivalent) color temperature LEDs for superior visibility as compared to yellower halogen sources. The higher color temperature light stimulates all of the cones in the fovea of the human eye, which is the area of the eye that provides the highest resolution vision. 6500K is also superior for air-to-air recognition since it looks like sunlight reflecting off of a mirror, where yellower light sources are not as attention getting.

Comparable Landing Light Performance
Our Sunspot PAR36 light produces 1500 lumens inside a 20 degree cone as compared to the 1500 lumens produced by a GE4509 bulb while consuming just 45 Watts of power vs. the 100 Watts of the GE4509. The narrow beam Sunspot PAR36 has a slightly wider beam pattern than the GE4509. The center of the GE4509 beam is about 100,000 candela while the Sunspot is 50,000 candela. This may seem to be a large difference, but the human eye is a non-linear detector so the linear scale of candelas does not represent the actual perceptual difference. To accurately show the perceptual difference, the candela profile needs to be plotted on a log scale as shown below. This is comparable to the decibel scale used for human hearing. Note that the Sunspot covers a wider and smoother angular range which makes it easier to see the full width of the runway on short final. We also have a wide angle version of Sunspot for use as a taxi light as well as a wider angle recognition light

TSO Compliance
We have designed our Pulsar and Suntail LED Nav/Strobe/Position lights to comply with the optical requirements necessary to achieve the FAA TSO requirements for Nav/Position light candela and Strobe 400 effective candela requirements.    The products that have a part number staring with a 11- are TSO approved by the FAA.
