Jim,
Replacing the switch with a toggle type dimmer will greatly lengthen the
service life of bulbs. I have them in bedrooms and the bathroom. The main
intent was to prevent being jolted awake by bright lights if it were
necessary to get up at night. Because they look like ordinary light
switches,

I dealt with a gentleman by the name of Barry Kennedy and he shipped
the equipment out same day when I needed it. The price was about $3,400.00

In the spirit of trying the simplest thing first, I'll swap the light switch
out for a new one and see what happens.
Thanks for the tip,
Jim

The subject of short life of light bulbs appears often on the
alt.home.repairnewsgroup.
People come up with potential sources of problems like "on the same branch
with the sump pump(or well pump)", and "long lines to the light bulb".
Their solutions were to put in those dimmer switches that c
On the subject of NTC's, please allow me a slight detour from the compliance
world to the real world.
I have a circuit in my house that blows light bulbs far more often than any
other. I can't determine any reason for this - the voltage seems normal and
there aren't any transient-producers on th
I need to rent the following equipment (preferrably in Darlington, U.K.):

* Spectrum Analyzer/EMI Receiver

Anyone know of a company?

I just discovered the Commission's statement on marking in the Sept. 1999

I have seen some design where NTCs are used to limit inrush currents in
motion controllers.
Q. Are NTCs safe and reliable as means to limit inrush currents?
Q. Are there safety considerations to consider for circuits employing NTCs?
Q. Are there any Approved (previously evaluated) N
Richard,
If you look on the Commission R&TTE pages there is a section in the FAQs
which relates to marking.
This states with respect to radio equipment that uses non-harmonised
frequency bands :
"With regard to the putting into service of these types of equipment the
"alert sign" shall be added
from 1999/5/EC article 10;
"3. Telecommunications terminal equipment which does not make use of the
spectrum allocated to terrestrial/space radio communication and receiving parts
of radio equipment shall be subject to the procedures described in any one of

Directive 93/68/EC (Article 5), which linked the CE marking to the EMC
directive, states that the minimum height of the CE marking must be 5 mm. The
Maritime Directive requires a CE marking which also includes the NB number. From
the example drawing in the directive it shows that the he
The DAPS link will get you only the latest release; i.e., 461E (462 is now

yet, so I still see a lot of 461D/462D requirements. You can get 461D, 462D
