[Boatanchors] New light bulbs

[kim.herron at sbcglobal.net]

Hi Gang!!
    I've got a bunch of these installed in the house.  They all came 
from a regional big box store here, and if memory serves, they are all 
Sylvania.  They are very quiet after start up.  That was the first thing 
that I did was check them with a broadcast band radio to find noise. 
Even the shortwave is quiet on the Kenwood and Collins. Love 'em!! 
They're especially great in a service lamp because I don't get burnt any 
more. I've also refitted a bunch of my four foot fluorescent lamps with 
new electronic ballasts and found pretty much the same thing.  The lamp 
ballasts aren't quite as quiet, but their pretty good.  I can run a 
dozen four tube units and still have a fairly quiet SW spectrum.  BTW 
the ballasts are made by Sunpak, the same people who make the electronic 
flash units for your camera.
