I have had some CFL bulbs last over 25,000 hours of operation. And yes, they were operated as abnormally as the ones he cites which were turned on & off every 2 minutes. Mine were low wattage (6W or 8W usually) and were almost never turned off. I mark all CFL bulbs with the date when installing them. I regularly get years of calendar use. Operating hours varies. Few fail within months. If you want best output per Watt, buy brands made by people who know what they are doing both in CFL manufacture and other areas. Philips' Gloeilampenfabrieken* is one such but there are others. The Philip Tornado CFL's were top ranked for output in tests arranged by an often reputable consumer organisation here and about 2 x brighter than bottom contenders. Philips publish lumen per Watt (when new) data on the packets and elsewhere. I'm adequately convinced that CFLs make economic sense in most domestic situations. And I've yet to find an incandescent equivalent to the 100 Watt electrical input CFL in my dining room light fitting that will fit directly in the fitting - or a daylight white incandesecent. ie CFL's are not perfect and not as good as some claim, but I deem them as adequately good. YMMV. I have no financial interest in Philips ... - just like their products generally. They even do an OK job of 'badge engineering' things. If they sell it with their name on it's more likely than average to be OK - here anyway. Russell McMahon * name changed in 1991, alas. I visited their original factory in 2003 - even though it had been utterly destroyed in WW2. Nicely rebuilt as a 'corporate monument'. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
