Other than that, can anyone suggest another alternative to the power
hungry halogens for outdoor lighting?
I dont have the data on them, but LED lighting typically ballparks
around twice the efficacy of filament lighting, so expect similar to
30w filament lamp as a first approximation.

The 150W linear halogens are far, far nicer than the 500W jobs in a
domestic setting if you must have a floodlight, but I've got a variety
of ordinary 'carriage' lamps with 60-100W bulbs in that do a fine job of
illuminating the outside at night.
I actually think the halogens are waaay too bright and simply shut the
iris up more than necessary preventing the eye's natural sensitivity to
low light levels.

Where are we going and why am I in this handbasket?
The LEDs in security lights seem to reach only a few metres, but
that's enough for my purposes.
I'm about to make an imitation outdoor gaslight. It will need to run
on 12V DC and I was thinking of using LEDs. I'd like it to switch off
in daylight.

Even a candle flame can do that for me, at night. I have very good night
vision and cars that drive round in bright sunlight with their head
lights on blind me.

Same here, but they do have to contribute towards pollution and terrorism
and it saves them having to look where they're going.
I like a gentle, warm-white outside light - much easier to see things. The
bulkhead fitting by my front door is just over half lined with ally foil so
that it doen't dazzle any one.

You don't understand Newton's Third Law of Motion?
It's not rocket science, you know.
Oh! I thought they were making the statement of...
'Look how important I think I am.'

Point noted for when I replace the tube in the light we have in the back
garden.

Yes, illumination is better than dazzle. Those damned 'lanterns' that glare
in all directions...! There's a house about a mile from here with 4 of them
and the footpath a couple of hundred yards away is unuseable at dusk.
