Относно енергоспестяващите, за хората които отбират Инглиш:

Четиво3С една дума защо няма да си сменя всички лампи с енергоспестяващи, поне тези при които винаги се стои. Предпочитам да платя малко повече за ток пред това.
Ето какво пише Род Елиът за тези лампи, кратка извадка:
...Should There be a Ban on Incandescent Lamps?
Health Issues?
The most recent information to hand (from a reader whose wife has Lupus) indicates that there most certainly are health issues. There are several auto immune diseases (Lupus being one of them), where UV light and/or light flicker cause sometimes extreme physical pain. See Wikipedia (Fluorescent Lamp, Other Health Issues) for more on this. A web search will quickly show that there are several conditions that create extreme sensitivity to UV light ... once you know what to look for.
For the remainder of the population, there is no evidence to suggest that humans are adversely affected by high frequency modulated light, but there is also no evidence that there are no long term effects. There is a great deal of concern (and a certain degree of conjecture) that fluorescent lamps of all types may contribute to health problems, in particular cancer. Try a web search for many articles that describe possible reasons in some depth.
Of particular concern is the amount of UV (ultraviolet) light that all discharge lamps emit - it is significantly higher than that from an incandescent lamp. Are these claims real or just s care mongering? Based on the information above, it seems that the claims are indeed real, and will affect a considerable number of people. Some additional scientific study certainly wouldn't go astray - preferably before government lunatics impose any bans on GLS lamps. This is a fairly hot topic on the Net, and a search finds a great many sites (over 1.2 million results) discussing the link between artificial lighting and breast cancer in particular.
Ultimately, it is better to err on the side of safety, but modern realities can make that extremely difficult. This information has been included in the interests of completeness, and the reader is advised to read the available information and make any decision based on that. It may prove that incandescent lighting is no better (or worse) than fluorescents in this respect, but it is not my intention to discuss this in any more depth than has been done in this section. I have neither the research material nor the medical skills needed to be able to make any recommendations, but it seems plausible that the claimed link between lighting and cancer may have some credibility - what we can do about it is another matter altogether.
If a lamp decides to fail and let the magic smoke out, there is definitely a serious health risk. Despite claims that the smoke poses no danger, it depends entirely which component it comes from. A burning polyester capacitor is very bad news - the smoke is toxic, as with most burning plastics. This also applies if the PCB is severely overheated and smokes or burns. Although it is uncommon for electrolytic capacitors to catch on fire, it has happened ... I've seen the results on a number of occasions. The fumes from burning ethylene glycol (part of the electrolyte in electrolytic capacitors) should not be inhaled - ethylene glycol itself is toxic, and the smoke is unlikely to be beneficial..
Never use a CFL as an all-night light for small children. Lamp failure could result in toxic fumes and possible serious injury.
