The Q4509 stands for quartz. Per the supplier: only difference is quartz version has a 100 hour lab life vs 25 hour lab life of the non-quartz version.
The difference is in the brightness. The bulbs with the X designation are brighter than the standard bulbs. In this instance, here are the specs: GE-4559 (Max Beam Candlepower = 600000) / GE-4559X (Max Beam Candlepower = 765000)
The GE-4596 bulb is still being manufactured and we still carry it. Use our part number 11-03806 (GE BULB GE-4596 28V 250W).
The difference is the beam angle. The landing light has a 10 degree angle while the taxi light has a 40 degree horizontal beam pattern.
Yes. The GE-Q4509 Quartz version is no longer manufactured. We recommend part numbers 11-12157 or 11-02220 as an alternative.
The halogen bulbs have no way of producing both a landing and a taxi light. These lights are designed to replace one or the other based on the GE part number of the bulb. If you require a combination light please see our LED landing/taxi lights.

GE bulbs were OEM parts on many production certified aircraft. The bulbs themselves do not have FAA Approval, however they are many times approved as replacement parts under the airframe approval. Please contact your local aviation authority to confirm the GE bulb can be used legally in your aircraft.
These are drop in replacements.
