I measured
I put a mark on the floor for 31 inches out.
Nose to ground, 45 1/2 inches
Center Horizontal Stabilizer 64 inches (??)
Center of Landing Lights, 65 inches
Center of Taxi Lights, 64 inches.
The bulbs say GE, no other markings. I suspect that because one of your lights is at 80 inches, that's the difference.
I turned off the lights in the hangar, and moved my hand on the tape measure to where it was centered on the on the wall.
Hint, do not look at the light, in a darkened hangar. Bad thing to do.
I had pulled my plane in last time, so it was pointed at the back wall (actually, I just drove it in, my wife had the door opening when I landed).
I checked on HID lights. The conventional GE bulbs are $20-$25 each. The HID lights are $500 each.
