These are almost exactly the same as normal tungsten bulbs, save that inside the large glass envelope is a smaller quartz glass enclosure, with a halogen lamp in that. <br /><br />They run at a higher temperature than the old tungsten lamps, so a lesser wattage of power is needed to produce the same output of visible light (a lesser fraction is emitted as infrared; not wasted, for it just heats the room). The ones I have are marked as "Energy Saving"; the small amount less power used, 42W instead of 60W, is apparently enough to satisfy the great god of Global Warming.<br /><br />Get shut of the fluorescents and buy halogens; they're better by far (at least until decent LED lamps are produced).Danhttps://www.blogger.com/profile/02618328278732100203noreply@blogger.comtag:blogger.com,1999:blog-3875365454966245098.post-36281163246746334082011-04-21T09:55:27.377+01:002011-04-21T09:55:27.377+01:00And, of course you can't dim them, something w...And, of course you can't dim them, something we normally do whilst watching TV.English Pensionerhttps://www.blogger.com/profile/15271488641341955140noreply@blogger.comtag:blogger.com,1999:blog-3875365454966245098.post-82505489888407094202011-04-21T06:33:35.035+01:002011-04-21T06:33:35.035+01:00Oh and I forgot to mention they flash 100 times a ...Oh and I forgot to mention they flash 100 times a second (unlike incandescents where thermal inertia stops the flashing effect). They also emit pure ultra violet (nasty for the eyes) which is tempered (changed) by using fluorescing powders (hence the name), which emit visible light.

And, this is a kicker, they consume far more electricity per lumen. Why? Because they have a lousy power factor (unlike standard bulbs which have a perfect power factor)so they are more difficult to supply and they make your electricity meter whizz round a helluva lot quicker. Power generators hate 'em.<br /><br />They were brought in to benefit two companies: Phillips and Siemens (who make the chips they all use) and had nothing whatsoever to do with energy saving.<br /><br />You just gotta love the EU, putting big business over the consumer every time.Kevinnoreply@blogger.comtag:blogger.com,1999:blog-3875365454966245098.post-78022240915670679072011-04-20T19:54:12.921+01:002011-04-20T19:54:12.921+01:00And that's in addition to the migraines which ...And that's in addition to the migraines which many people suffer as a result of their use. I've put the old lamps back in our lounge as Mrs EP,who would normally have suffered an evening migraine about once a month started to have them about twice a week. Her GP admitted that he'd had more patients lately who had mentioned migraines but that she was the first who had identified a possible cause.English Pensionerhttps://www.blogger.com/profile/15271488641341955140noreply@blogger.com
