Prior to installing AeroLeds landing and taxi lights on my Husky, I did a comparison test:
This is the halogen Q4509 sealed beam on the left, the AerLed 36 on the right . . .
Q4509 on the left, 55 watt HID on the right . . .
This is the AeroLed taxi light (wider beam than landing light) . . .
I also compared my AeroLed installation to another Husky with Whelen Parthmeus LEDs at the Root Ranch Husky fly-in in Idaho (across a large dark meadow). The AeroLed totally trounced the Whelen (not surprising as AeroLeds is double the wattage).
Aviat provides the option for full AeroLed LED lighting (landing, taxi, nav, and strobes) on new Huskys.
LEDs have a number of advantages over other types of lighting, longevity, effeciency, fast rise and fall time (i.e. instant on and off for flashing, wig-wag - - more attention getting). HID can often be flashed too, though you typically have to turn it on steady first, let it warm up, then turn on the Pulselight (or other flasher). Incandescent bulbs have a slower rise time - - not nearly as good at being seen with peripheral vision.
Hope the photos work . . . haven't tried posting them here before,
