Do you think my factory installation using high bay fittings is bad design? A single high bay fitting is not designed to light an entire factory.
How many halogens per switch?

If you think the comparison is valid, pray explain why the installation doesn't consist of a few thousand 2" diameter lights?
Big room = big lights
Small room = small lights

Small room = small lights

No.
Room = lights designed to light the room, in a quantity related to the size of the room.
Room ≠ a much larger quantity than that because the lights chosen are ones designed to not light the room.
Yes, but you probably can't help it.Simples

They're not in a much larger quantity. They're just smaller and closer together because the room is smaller.
We also use PL downlighters or recessed mods in an office. Medium sized lights in a medium sized room.
They're all exactly the same lighting scheme.
Can you explain why these installations all use lots of individual fittings to give an even spread of light rather than one big bright fitting in the middle of the room?

Like anyone would use wax candles to light a room up these days
, you missed the point of my joke.If that is so, then you would be happy with 1W of LED light distributed over the whole room?
The wattage is NOT irrelevant, you want the wattage to be as low as possible while still sufficiently lighting the room up.
Also BAS how many lumens would you expect to be needed to light up a room 33.5 meters squared.
BAS can you also give me an example of "a light what is designed to light up a room" suitable for a room the size of my kitchen.
Getting back to the original question.
How many halogens on a switch
Some halogen lamps have a very low impedance when cold ( compared to an equivalent wattage non halogen lamp ) and thus take higher currents until the filament reaches operating temperature.
A six amp switch will ( should ) have a long life span switching 1440 watts of lighting (6 x 240 = 1440 ) but may not last so long when switching 1440 watts of halogen lamps.

They are in a larger quantity.
Please read it again.
So if you need X lights designed to light up rooms, and then you decide to use lights designed to not light them up, and therefore have to use Y of them, where Y>>X you have a much larger quantity and that's the offence.
Because one big bright fitting in the middle of the room wouldn't work very well.
So you use lights designed to light up rooms in a quantity related to the size of the room. Why, in these medium sized rooms, don't you use hundreds of recessed 2" diameter ones?
No, I didn't.

But you then repeated the same sort of assertion. I don't think you have ever been in a proper lighting shop, or looked online at proper lighting suppliers - you appear to have no idea that there are choices apart from traditional GLS pendants, fluorescent tubes, and 2" downlighters.
The wattage is irrelevant.
The offence is using lights for something they are designed to not do.
Don't know.
Only if you can show me where I have suggested the use of a light.
They are no larger in quantity that the factory scheme. They are just smaller and closer together.
Why is it ok for offices to have multiple smaller lights spread evenly across the room instead of one or two huge lights, but not for domestic homes?
Because they're medium sized rooms, so you use medium sized lights.
Large room = large lights
Medium room = medium lights
Small room = small lights
BAS you keep saying wattage is irrelevant, but can you justify why the wattage is irrelevant.
IMO while the wattage is not the primary concern and lumens and light distribution is, wattage is far from irrelevant due to if the wattage is to high for a given light output it will cost to much to run and not be economical, equally if the wattage is to low you won't be able to get enough lumns to light the room up properly.
As I said you want a light source/s that lights up the room to the required brightness whilst consuming the least amount of energy.
You get what I mean; ok then show me "lights what are designed to light up a room".
On a side note; would you use 2D lamps over spot lights to light up a room like my kitchen by any chance as well BAS?

The ones in the factory are designed to light up rooms. 2" recessed downlighters are designed to not do that.
It's fine for both to have them as long as what they have are lights designed to light up rooms. 2" recessed downlighters are designed to not do that.
No.
Room = lights designed to light up rooms.
Small room ≠ lights designed to not light up rooms.
They are designed to light rooms.
Because it is not the consumption of 2" recessed torches that's the problem. It is the offence of using them to light rooms when they are designed to not do that.
But it must be a light source designed to light up rooms, not one designed to not do that.
Lots here.
It's OK - we all understand that you are clueless and ignorant of what lights are available, there is no need for you to keep demonstrating it.
