They believe well they make, and his health If we are to believe the British Agency of protection of health is threatened, some lamps with low consumption issue ultraviolet rays in relatively important quantities. To the point where organism recommends to avoid putting lightings of this type too much near the users. A distance of in - less thirty centimetres is recommended, unless bulbs include a second glass envelope, which makes them resemble in bulbs with incandescence.

The fluorescent-compact bulb is a fluorescent tube, wrapped on itself to hold in the volume of an ordinary bulb. He shows a five - six times as weak consumption as bulbs with incandescence, with equivalent brightness. What makes an instrument of choice in the hunt for the energy wasting in the field of lighting.

Where the pack-saddle hurts, it is that some of these bulbs, certain only (1), issue ultraviolet rays known to cause skin diseases, going up to the mélanome, formidable tumour. Experts of the British HPA measured that in two centimetres of distance, some models of bulb display as much to the ultraviolet rays as the British sun a nice day of August. As soon as they move away, the level of exhibition is equivalent in a sunny winter day in the kingdom of Elizabeth II, what threatens nobody, far needs.

Good news in all that, it is that it is finally rare to think more than some seconds in it is immediate nearness of a bulb. Besides, is recovering the British Agency, all bulbs covered with a glass envelope which conceals the fluorescent tube issue UV only not much. The glass skin indeed absorbs the most part of this radiance. Also, the classical, linear tubes, used to light corridors and offices, do not pose particular problem because of the distance which separates them from users.

Strong in this inquiry, the British government is going to intervene to Brussels to try to influence the texts which govern usage, sale and importation of these bulbs.
