From the LoPresti website, a possible solution to the short life of landing light bulbs…
Advantages listed are:
Longer Life, Lower Power Requirement.
Bright-600,000 candle power, available in spot or flood versions.
Metal Halide - Xenon - High Intensity Discharge Light System. Very white light, close to daylight color - (like the new Lexus, Porsche, Mercury Headlights).
Warranty includes bulb burnout, estimated 5,000 Hour Bulb Life. No filament to break.
Reduces load on alternator, system uses less than 3 amps. Voltage 14 and 28.
Link to AOPA Pilot Product Review, from Feb 2001:
A long lasting, bright landing light would also be nice to have as an anti-collision device in busy airspace.
Any news on the relocation of the landing light in the cowling?
