incandescent Edison bulb is good
the new bulbs cause cataracts Ive heard and epileptic fits etc
The "new" bulbs are just a compact version of the ordinary fluorescent tube. Oddly enough, the country's shops and offices, all of which seem to use loads of flo' tubes aren't noticeably full of blind epileptics.
I have been using them since 1997 all over the house and neither epilepsy or cateracts, and the best way to use them is to turn them on then leave them on until bedtime thus saving on electricity.

From the Epilepsy Action website :
Compact fluorescent lights (CFLs)
There are different types of low energy and energy-saving light bulbs available.
Compact fluorescent lights (CFLs) are the most commonly used. New generation CFLs are virtually flicker free, provided they are in good working order. They are, therefore, unlikely to trigger seizures.
Some of the older generation CFLs can flicker on start up. However, the very high flicker frequency means they are considered to be no more of a risk than [fluorescent strip lights] or incandescent bulbs for most people with photosensitive epilepsy.Â
Note that they are referring to triggering seizures in epileptics. There is absolutely NO evidence for lights of any kind CAUSING epilepsy.
Cataracts are largely a matter of aging, but there are some grounds for thinking that UV light has a role in their development. A full year under compact flo' bulbs will expose you to about as much UV as an hour of sunlight.
Go figure.
if i have time ill get the link from Wikipedia on light sensitivity
i feel im affected by these bulbs
theyre bad for lupus and other things
the old fluorescent lights are bad too unless they are very far up in ceiling and even then bad
the cfl cause pets to leaves rooms ive read
the cfl bulb emits sounds waves as well
at least i demand the option to buy any type of bulb
Bit late now, Norman, unless you can find an old fashioned shop with a hoard of old ones in the cellar.
Do your research on knowledgable sites, don't just rely on hearsay or Wiki. Ask your doctor if you are really concerned.
You can save about as much electricity by using halogens.
BTW - Incandescents flicker too at 100 hertz.
Never mind, there are always candles.
And candles won’t hertz your eyes
This is the History board, not a general chat board.
Candles are historical LairigGhru.
incandescent Edison bulb is good Â
We only associate Edison with the light bulb because he aggressively marketed his bulb. He certainly didn't invent it. Joseph Swan successfully sued Edison for infringing his (Swan's) patent.
Candles are historical LairigGhru. Â
Many women must have mourned the passing of the soft, flattering effect of candlelight. Harsh artificial lighting can make any woman over twenty-five look an absolute fright.
There's a story about Wallis Simpson's presentation at court 1931 - as the royal family walked out in a slow procession, WS chanced to hear a casual remark the Prince of Wales made to his uncle, the Duke of Connaught. "Uncle Arthur, something ought to be done about the lights," he said. "They make all the women look ghastly."
Candles of course were also very dangerous - the tales of huge Pompadour hairstyles catching fire may seem funny now, but there must have been some pretty awful accidents caused by this very romantic form of lighting.
Well candlelight is definitely more flattering on looks but it would have been horrible to read or sew using candles. People's eyesight must have been ruined by an early age, so in that regard better lighting would have been welcome.
Although the poorer, worn out by a days hard labour, generally went to bed very early anyway so possibly they didn't welcome anything such as good lighting that would extend a day.
That so LairigGhru… but with the deepest respect nor is it a board for you to rebuke me for a light hearted comment regarding the use of candles over the compact fluorescent lights (CFLs)…
I say again: And candles won’t hurt (hertz) your eyes. Is there no humour allowed in history…?

the history is the light bulb was invented over a 100 years ago
do gooder" liberals" in USA and uk etc outlawed the old ones for the new ones
some like the old ones
some voted republican because theyre more open to choice
Republicans are pro choice
the republicans may bring back the option to make and buy both
the democrats in usa spew out their green doctrine like a new gospel
i like the old bulb
cfl bulb will give you cataract
google cataract and see if they have risen in past 10 glorious years of green cfl living
i think its true
Where I grew up as a kid, apart from the very major road junctions where they had those dreadfully dull sodium lights that made everything look like it had been tango’ed… everywhere else had gas lamps which were ok, so long as you stayed under them. Mostly they seemed a prime target for the local kids to try playing hoopla with bicycle tyres…
Gas street lighting seemed to me to disappear around the 60’s but when was the last time you saw one… remember that the old lamp post remained as street furniture for a time after being converted to electric lighting.
Are there any gas lamps still in use… I know of one village still using gas, but are there more…?
the history is the light bulb was invented over a 100 years agoÂ
It was. It has quite an interesting industrial history too. Since Faraday first demonstrated that passing current through filaments could make them glow, the race was on to find a way of stopping the filament burning out. Swan and others readily realized that placing the filament in a vacuum would lengthen its life. Light bulbs then had to wait until methods of making and maintaining reliable vacuums coudl be found. Swan beat Edison by the best part of a year. (Others claim to have beaten Swan to it).
cfl bulb will give you cataractÂ
No, they won't. At least not any more than incandescent lightbulbs.
google cataract and see if they have risen in past 10 glorious years of green cfl livingÂ
I tried and couldn't find anything. Can you post the link please?
Cataracts are largely a degenerative disease brought on by old age. Between 1998 and 2008, US life expectancy went up 2.3%, so you'd expect an increase in cataracts corresponding to that without changing light bulbs.

The first town in Britain to have streets illuminated by gas lighting was Muirkirk - close to William Murdoch's home.
The last town in Britain to get natural gas was also Muirkirk.
My apologies to bandick and anyone else who was upset by my remark, but up to that point it seemed to have been predominantly a chat about the merits / de-merits of the new energy-saver lightbulbs.
And none taken by me LG, I suppose in the dimness of a decent light any amount of errors can be made.
As far as my comment on gas street lighting… the village I am referring to is Throop and Holdenhurst, only a few miles outside of Bournemouth… and still they burn dimly.
Are there any gas lamps still in use… I know of one village still using gas, but are there more…? Â
Bristol had a gas-lit pub until it closed last year. Don't know of any street lights.
