No more light bulbs! (..after this last expensive one!)

[mistermack]

I don't get it.

The compact fluorescent bulbs that I have, DO have a warm tinge. ( bit yellow ). It's the one thing I don't like about them.
I prefer the "daylight tone" whiter light, but the cfl ones with that whiter tint are more expensive.
( Or I'm too mean ).

And LED bulbs have been around for at least a year. You can buy them on ebay for less than £10.
But I wouldn't pay that for a lightbulb. The cfl ones last for years anyway. And you can still get them in our local 99p shop.

I would prefer LED, and I have LED torches, but I wouldn't dream of paying that much for a light bulb.

Can you find the filter covers that change the light to a whiter shade?

I've never seen them advertised.
I suppose it's possible, but it would soak up some or a lot of the light, so you'd lose efficiency.

Philips was the only entrant for the competition and its design underwent 18 months of testing before being declared a winner.

So how do they know it'll last for 20 years?

[Svartalf]

their eggheads calculated it?
or maybe the project is a lot older than it looks and they had actual date?

Scientifikly. They got twenty bulbs and turned em on for a yur.

Yeah, you'd use a "100 watt" bulb instead of a "75 watt" bulb for the same amount of light.

However, I just exchanged some email that tells me they won't be on the market for at least a year.

Why not get 240 and burn them for a month?

My local Morrisons sells both, you have to check them though since the packaging is identical apart from the lumens info and spectrum info on the back. There should be no difference in price between blue/white and orange/white ones.

Homebase sells them and once a few years back I got a 250 watt blue/white one from B&Q for my study, but it was far FAR too bright for a house. You would have thought I was constantly igniting phosphorous.

Here's a strange but interesting fact.

The Sun is actually almost white, but looks yellow. This is because the blue part of sunlight get's scattered by the atmosphere more. That's why the black sky looks blue, and the white Sun looks yellow.

Remove the blue component from the white Sunlight, and it looks yellow.

But on a cloudy day, the clouds remix the yellow and the blue, and so the daylight is the original white again.

So you could turn yellowish light white, with a blue filter. But you would lose brightness.

You could just paint all the walls in your house blue.

I doubt if they will last twenty years. There isn't anything 'lectrical that lasts as long as that and leds are the first to go.

Collect your worn out CFL's and take them to an official disposal centre - the bulbs contain mercury, not good for landfill...

[Svartalf]

Would be nice if they made disposal easy... I've never seen a used bulb bin in the store where I buy my bulbs, and don't know what to do with them... and since the supposed "green" and "citizenly" sorting of trash for recycling is actually a concealed benny for some industrial lobbies rather than a real effort to recycle, the recycle bin I put, say, my paper products, metallic items and plastic bottles (but for some reason they tell us not to put soft plastic baggies in there, although they are PET like the bottles) is not supposed to accept bulbs either, I don't have an officially correct solution for those.

About time we stopped burning tungsten. It is needed for much more important stuff than lighting

... like armour-piercing warheads.


Ans why is it so difficult to get an energy-saving bulb with the same brightness as a 200 watt incandescent bulb?
