I hate the damn things - made worse now with LEDs. I want to see the effect
of a light - not the light source! Seeing the source just makes everywhere
look darker as you eyes try to cope with the bright source.

It used to be that the bulb was shaded so the light would actually only light
its area. I tin-foil my bulbs after finding the light's stronger and covers
almost twice the area.

Ali drink cans can be cut open to give reflective al sheet, this fits well into some light fittings, much improving output.

With bulkheads I put ally foil under the cage or, if no cage, inside.
My latest outside luminaire is the upsidedown-type lantern with a 120 deg.,
6000K, R63 LED lamp. It's actually visible from 30m away and slightly above,
but not dazzling at all.
I've since turned the bulkhead onto its end and used the same sort of lamp.
This arrangement is also dead easy to shade with a miniskirt aroung the edge
of the lamp.

This reminds me of the problem with some of those high pressure Mercury
vapour streetlights they used to install. Plenty of light but everything
looked like it was cardboard cut outs and the dazzle was terrible from the
lamp.
I thought bulkhead lighting was mainly for use in emergencies or in certain
exposed outside places?

I'd say it is meant to be used where you can't fit an overhead light. Due
to a low ceiling or whatever.

LEDs do make things worse as they appear brighter if viewed directly.
Sadly, this doesn't translate into useful light.

I was using a generic term Brian for the type of fitting that is basically
a transparent box for a bare lamp mounted - typically around the walls of
commercial buildings. The light just spills everwhere.

I recommend amber driving glasses, or clip-ons.

They conveniently cut out the intense blue of the 'cold' xenon lights.

Lots of better choices are available - but I suspect electrial Contractors
just fit what suits without much thought to light spread or pollution.
Likewise domestic floodlights aimed horizontally so that 50% of the light
is wasted.
