You should get the story of the various "competitive" ordinary electric light bulbs (with life span up to 10 times what GE manufactures) but which were "bought out" rather than marketed......

Dayton" Newsgroups: sci.engr.lighting Subject: Fluorescent Lamps vs the Utilities - 60 years ago Date: 16 Feb 1998 17:32:31 GMT The fluorescent lamp was first marketed in 1938. The introduction of fluorescent lighting was initially very disconcerting to the utilities. You may pay your Electric Bill but your parents and grandparents payed their Light Bill. For many years, the major business of the utilities related to lighting. The utilities projected a drop in power requirements due to the lighting efficiency of the new fluorescent lamps compared to incandescent lamps. The utilities proposed to carry over to the new light source the principles which had been developed for incandescent lamps. Despite the low surface brightness of the fluorescent lamps and greatly reduced glare, they insisted that all fluorescent lamps for general lighting should be shielded. The fixture manufactures complied in many cases and the lamp efficiency was reduced by as much as 25% and more lamps and power consumption were required for a given level of illumination. The final objection by the utilities was that the fluorescent lamp had a low power factor, which would tend to limit the capacity of the installed wiring and was in general costly to the electric companies. The objection was valid but all that was necessary to correct the problem was to add a capacitor to the ballast circuit. The lamp producers met the demands of the utilities and on May 1, 1939, General Electric issued a statement of policy which included the sentence "The fluorescent Mazda lamp should not be presented as a light source which will reduce lighting costs." Westinghouse stated "We will oppose the use of fluorescent lamps to reduce wattage." and then there was harmony. Now of course, lighting is a small fraction of the "electric bill" Dave Dayton Archive provided courtesy of WaveGuide, http://www.wave-guide.org Reprinted with permission of Roy Beavers, http://www.feb.se/EMF-L/EMF-L.html
