Purchased two Galaxy 4553 28V landing lights to replace GE4553 bulbs. The Galaxy lights have three bumps on the back and a curved front lens. GE bulb has a flat front lens and single bump for indexing on the back. The Galaxy 4553 bulb will not fit where a GE4553 bulb was installed. Do not buy as a replacement for the GE bulb
Purchased a Galaxy 4313 for installation on a Bonanza A36 Taxi Light. The outside diameter on the Galaxy bulb is 4.440 while the OD on an original GE 4313 is 4.340. The Galaxy may not fit because the tolerance is not the same as the GE bulb. Otherwise looks like a good, robust part, for applications where size isn't such a factor.
Per the manufacturer, no they are not FAA Approved.
While the Galaxy 4591 is a great landing light, it is not FAA approved.
No, they do not hold a FAA/PMA approval.
The 4313 bulb is a PAR36 bulb, with a diameter of approximately 4-1/2 inches. The 4522 bulb is a PAR46 bulb, with a diameter of approximately 6 inches.
