Aim is important - too many are aimed to dazzle the housholder and the
people across the road and to light up the sky. The design assists this bad
practice.

I found one, earlier in the year, where the solar panel is on a long cable
away from the light. This means the light itself can be mounted where the
sun never shines.

Sounds uncomfortable!

Strange, unless the 70W sodium was on the way out. When new, the latter
gives around 5000lm, compared to less than 3000 for a 30W led.


It wasn't on it's way out. But yes, it is strange. It could be
perception; yellow light versus white light.

That was my thought.

A string of low power lights from the house to the shed sound more
ideal, a little catenary with a 12V feed from the house. We've been told
it is just 5m away too.

A floodlight on the house would be a better bet.

The OP isn't helping by not giving us the true picture of what
management is trying to achieve. It could be to simply draw the moths
away from the house? We don't know.

Although if getting power to the shed for the light on it, you may as
well also stick one in it while you are at it.

I guess so. But (if I remember correctly) it makes me wonder why - maybe
30 years ago - there were recommendations for using yellow-coloured
glasses when driving at night to improve vision, particularly when it
was foggy.

A particular problem if used in a WC used by gentlemen.

Someone very near has recently put up a small, PIR light which spills over our fence. Walking towards it (as in down the drive to the front door) night vision is totally wiped out - but it doesn't light the ground, so doesn't help in safely walking.

Management is asking for a light on the garden shed. It's around 5
metres
from the house with a paving slab patio between the two. There is a
possible route round the edge under some block paving and then under a
gravel run.

Could the supply be taken from, say, a fused spur fed from the nearest
internal 13 amp socket (the utility room)? If so, what cabling and
protection would be required between the two?

This is not necessarily DIY but I would like an idea on what to expect
if
we go ahead and put it out to a professional.


If it's just for use as an outside light to show you the path, look at a
battery powered LED security light.
As it's LEDs & only on for minutes at a time the batteries last ages.

I found one, earlier in the year, where the solar panel is on a long cable
away from the light. This means the light itself can be mounted where the
sun never shines.


Battery powered, not solar, which allows them to be mounted where most
convenient.

Of course it will depend on whether the OP considers them a suitable
solution or even a partial or temporary solution.

Last year I installed 3 for different OAPs. 2 over their back doors to show
up any callers & give a little light to the path. The third was mounted on
the inside of the gate on a 20m long pathway to show the way when she came
home after dark.

Battery powered, but solar recharged. Like a great many devices.

They're not bad in cutting out the blue light from HID or LED lights.

I have used clip-ons to some success in an otherwise well lit area.

No 'cause unless the house is a bungalow you can have the light much
higher.

Tell me about it. There's a fram across the valley 3/4 of a mile away
and 275' lower than us that used to have two(*) LP sodium lights on
when every it is dark to illuminate up their yard. We get enough
light from them to cast very decernable shadows, in fact you can
probably read by them!

The design assists this bad practice.

Most flood light are badly designed, they all ought to be designedso
that you have to make special effort to send any light above the
horizontal. WTF this farm wants to light up half the valley and sky I
can't imagine. It's wasted light, tilt the fittings down and they'd
have more light in their yard.

(*) There's only one now, perhaps one has failed...

That's very bright.

For an LED, yes, but about the same as an old R7 120W halogen (and at
least you can change those when they fail).

There are many places where 30W LED is held to be more or less
equivalent to 300W halogen.

Got any links for those? From what I've seen, available 30w floodlights
are around 2400 - 2900lm
(https://cpc.farnell.com/c/electronic-electrical-components/optoelectronics-leds-displays/leds/led-floodlightings/30w-led-floodlights?pageSize=50)


300W R7 halogens are around 4600 - 4900lm. Screwfix appear to be doing
230W R7 halogens which give 4650lm. Their 120W bulbs give 2250lm.
https://www.screwfix.com/c/electrical-lighting/light-bulbs/cat8350001?lightbulbtechnology=halogen


Plus, typically, LEDs have at least a slightly higher colour
temperature which changes effective vision significantly.

I assume "floodlight" leds are usually supplied at that higher colour
temp, rather than the choice you get with, for example, GU10s.

You can still get them in a range of temps from Warm white through to
daylight.

FWIW I replaced a 150W linear halogen with a 30W LED flood[1], since it
gave a similar theoretical lumens output. In reality I find the LED is
actually quite a bit brighter, and a 20W would probably have done.

I did similar but following advice from a denizen of this group I paid
about a fiver for two of the cob lights direct from aliexpress and
mounted them on an offcut aluminium extrusion clipped to the ceiling.
All run off an earthed 3 pin plug.
