IIRC its due to the fact that low energy bulbs are compact flourescent tubes. For reasons I dont understand these "strobe" (flick on and off very very quickly 100s of times a second) For the majority of people it isn't noticable but some people can find it uncormfortable.Annpan wrote:

I think it's a matter of getting used to the tones that they emit.
You're absolutely right, low energy bulbs are the only way to go to save the planet. I completely agree with you that dictating what other people should do is repellant. Some times though for the good of public health banning something has to be done, take asbestos as an example.DominicJ wrote:I use energy savers, but thats because I'm tight and lazy.
I usualy always find forcing someone to behave as someone else dictates repellant, so I'm against banning incadescants.
clearly there will be situations where energy saving light bulbs of the 'tube' style are not suitable, for medical or industrial uses. There is an alternative though, LEDs (Light Emitting Diaodes). As far as I know they don't flicker, can be very bright if required, and the colour spectrum could be adjusted to just about any situation.Brod wrote:Annpan wrote: It was found (the hard way i suspect) that using tubes over a spinning lathe if the frequency of the tube and the RPM of the lathe coincide the strobe effect of the tube caused the lathe to appear stationary, enter hand of the unwary....
They have. Not all, of course - but we had an asbestos factory in the town where I grew up, and there was more than one case of - sometimes quite late onset - severe respiratory suffering.DominicJ wrote:I'm going to get slated for this, but I think asbestos is the most overblown "crisis" ever.
Please, correct me if I'm wrong.
People have worked with asbestos there entire working lives and not died from it.
I know this a a rather late reaction - but I didn't see it before. Ann, tell her to get a daylight bulb; they use a little more than the normal savers bulbs (about a quarter instead of a fifth), and they cost a lot more, but they are brilliant. I bought one exactly for that purpose, as I couldn't see my navy blue knitting under normal light.Annpan wrote: My sister - who does alot of sewing, knitting, etc - hates energy saving ones, she can't focus under the energy saving light, and gets headaches.
That is an excellent suggestion, when working as a graphic designer we always has a daylight 'box' which was a drawing board cased in on three sides and a ceiling, which has just daylight fluroecent ligthing so we could always check printers proofs under guarenteed 'daylight' so the colours were correct, no nasty surprises when the books were in the shop window.
