No easy way. You are better off with the incandescent bulbs as those
screw type florescence are a mercury hazard and depending on the
instillation they will not last long.
The best use for the energy efficient bulbs are ones that are not
switched on/off often and are mounted upright. That eliminates most uses.
A better system would be low voltage quartz or LED type lighting but
that takes rewiring the house.
Incandescent bulbs release way more mercury than the occasional broken
CFL.
You will have to explain that one.

- Most electricity is produced by burning coal, which contains
mercury.
- There is mercury in the smokestack emissions from coal plants. *The
- extra mercury released by the power plant in the lifetime of an
Edison
- lamp is more than that spilled by a broken CFL. *Simply a matter of
- arithmetic.

to, which can cause cancer.


You get more UV from walking in the sun for a couple minutes.

Some of the CFL's are putting out high levels of UV and should be
avoided. The quality units don't have that problem.

I'd switch brands. I have, in over 20 years of using small
fluorescents, found very few that made electrical noise. What
brand lamps are you using? You're not trying to use them with
dimmers, are you?


Agreed... I've had mini-fluors in a standard lamp and a table
lamp, both within a metre either side of my Eton E1, for several
years with only one instance of a "noisy" tube. That's now in a
lamp in another room where it's seldom turned on.

Those are not the same thing as the CFL's being discussed. The older
lamps have low frequency ballasts where the only radio noise they
generate is at startup. The noise stops as soon as the bulb plasma
is conducting.

The current generation of high efficiency bulbs use a high frequency
oscillator to excite the plasma in the bulb and this is a constant
source of interference depending on brand and location. This is an
insidious problem because it is location dependent.

Er, am I dumb or what?

My response refers to Dave's answer "in over 20 years of using
small fluorescents..." and your own response to the OP McFerg where
you also refer to "screw type florescence" (sic).

This household uses several newer/older (or older/newer) minis, as I
say with only ONE RFI problem.

I will add that my Eton is "mains powered", not battery.

Yes you are mistaken. The discussion is the new energy efficient type.

No easy way. You are better off with the incandescent bulbs as those
screw type florescence are a mercury hazard and depending on the

The best use for the energy efficient bulbs are ones that are not

A better system would be low voltage quartz or LED type lighting but
that takes rewiring the house.

CFL.

You will have to explain that one.

I turn mine on and off just like any other lamp; *no ill effects.

If you use them upside down in any ceiling fixture you will shorten the
life of the bulb.

I use them vertically, horizontally, and at various angles in-between.
Again, no ill effects.

If you are turning them on and off all the time you will shorten the
life of the bulb.

There are LED lamps that run on 110 VAC.

Those have switching power supplies that should be avoided.

Indeed. We found out the hard way with our patio light, it is upside
down. After going through three bulbs in 7-8 maybe nine months, I
switched. Maybe the moisture of being outside also had something to do
with it.

That is true what you said, I've never read that but the two bulbs we
do use in the house are vertical and we leave them on all the time and
as far as I know not one of them has expired yet.
