Thanks. It would be cap side down in the fitting (a coach lantern), so
most of the light would be pointing upward into the cap. Perhaps I
could line the cap with some alu foil to reflect the light.

I recognise the lantern design. I put half silvered conventional lamps
in mine which works surprisingly well. I inherited a box of them from a
previous owner of the house and that is the only place I can use them.

Putting no light upwards is actually a
benefit in an exterior lighting situation avoiding light pollution.

It illuminates a path so I do need some light out the sides.

It won't put as much light sideways as a traditional filament bulb but
it may well provide enough and will be less dazzling. You would have to
try it and see - I am not easily impressed but I was by this unit.

I might well do that, or try another of the corn bulbs discussed
recently. The first one I got, a couple of years ago from China, is
very poor.

I'd suggest sticking with one of the better known brands.
Samsung have gone up in my estimation recently.
