Reply to: Sales of 100W incandescent light bulbs surge

[expat]

There is no 'Law' on light bulbs. There has been no vote in Parliament on this.

The light bulbs are being phased out from this week via a "voluntary" agreement with Britain's retailers.

I'm starting to believe its pointless voting anymore.

A voluntary agreement between retailers and whom? Not me.



IMO a Government initiative that has an effect of compulsion on citizens, even if the initiative itself is voluntary rather than compulsory, requires the assent of Parliament to ensure that the Government is exercising only its legitimate powers (ALL of which derive from the people, who delegate them to Government). I see that HMG has anticipated this attitude, and they describe the initiative as "retailer-led". Oh really? Retailers led this initiative (including the obligation on them to provide a means for recycling used lamps), so the Government is not forcing anything on anybody, so requires no validation. No. No.

Q. How many politicians does it take to change a light bulb law ?

95W floating around your ceiling, the worst place to generate heat. Or even, floating under the floor of you have a light inset into the ceiling.

What, and staying there and never coming out?

Ce qui est vu et ce qui n'est pas vu (Bastiat):

100W bulb: 5W of light. PLUS 95W of heat.

Result: 95W less for your CH to do. Real efficiency not nearly as bad as the oft-quoted 5%.

Plus, I don't normally want any heating... maybe in the winter it's OK but I still like to see when the weather isn't bitter. And in a modern house even the lights could make the house too damn hot, the amount of insulation in the walls/roof.

Open door and wedge with foot - reach back to switch, turn one on, look which bulb is illuminated, repeat.

No.

Bollocks - I bet I could do it like that. My arm span is well over 6ft.

turn on switch 1

turn on switch 2 - then off after a few seconds

leave 3 off


go inside room

1 light on - switch 1

1 bulb warm - switch 2

1 bulb cold - switch 3

Of course. The key is that you only have one bulb too many for the simplest imaginable test (one on/on off), so you only have to think of one trick.

The answer is to do with feeling the temperature of a bulb though?

expat was along the right lines yes

There are 3 lightbulbs inside a room with the door closed and no windows (ie you can't see into it). There are 3 switches on the wall outside the room. If you are only allowed to open the door and enter the room once, how do you work out which switch operates which bulb? (Clue: The lightbulbs are initially switched off).

Yes.

No.

Laconic.

[moorfield]

Switch them on in order, then enter the room before any has warmed up, and observe the order of warmup.

No.

Does each switch operate one (and only one) bulb? Only you didn't say.....

Yes.
