Re: compact fluorescent bulbs

["Shapiro, Mark" <mshapiro@EXCHANGE.FULLERTON.EDU>]

I converted most of my home lighting to compact fluorescents during the
California energy crisis more than a year ago.  I used a mix of name
brands, GE and Phillips, and no name brands.  So far, they all are going
strong.  Our electricity usage dropped about 50% after the changeover.
I did notice that a few of the bulbs that have the heaviest usage now
take a little longer to come up to full brightness than they did when
they were new; however, the light output is not noticeably less.

if off brand means foreign, OK.  Osram makes discharge lamps for
Chemists and Physicists.   It appears they "own" Sylvania:

Welcome to OSRAM SYLVANIA, the North American
division of OSRAM GmbH - one of the world's largest
lamp and materials manufacturers.

Not so foreign?
