Just that "normal" LED lamps expect to be hanging down in a pendant so the
light mostly shines down, where a bulkhead fitting often has a reflector
(which would be at the top when ceiling mounted) to reflect the light out
of the side of the bulb downwards.

No

It's screwed in a horizontal position with two fittings for bulbs - one
pointing up and the other down (or one pointing to the right and one to the
left - or something in between)
