If the pilot lamp is a neon lamp of C2A/NE-2H or A1C or similar type,
the power consumption of the neon lamp and its associated dropping
resistor (for 120 volts AC) is usually around 1/3 watt.
I don't remember too clearly what I found in terms of current and power
numbers for one with an LED pilot lamp, though I do think that .4 watt
sounds about right. This can be halved with noticeably increased LED
light output if an LED costing a few cents more and much more efficient is
It appears to me that the USA national average is about 11 cents per
KWH, maybe now closer to 12, and at least will be 12 soon.
1/3 watt at 12 cents per KWH for 1 year costs about 35 cents per year.
An InGaN green LED that gets plenty bright at half a milliamp (.06 watt
at 120 VAC including dropping resistor losses), plus dropping resistor and
bridge rectifier, in production quantities may cost 15 cents more than the
neon lamp. Add some more for likely a little circuit board and assembly.
I guess the retail cost goes up a couple bucks, maybe just one buck should
they sell by millions, to save about 30 cents a year (plus however
electricity rates inflate in the future).
I would buy them at that rate. Sadly, too many people won't even spend
extra up front two years' worth of electricity savings for a more
efficient model when shopping for refrigerators!

If you can even measure the difference...
And, of course, by disconnecting the range clock you've also disabled
the auto-on/off feature...
As an aside, it would seem quite unusual for a wall-sourced electric
clock to not be pretty accurate since grid frequency is normally pretty
The clock in our old range stopped working 10 years ago but it was still
right twice a day. New range has no clock, no electronics, no circuit
board, just plenty of power to cook with. www.bertazzoni-italia.com We got
the black 30"
OTOH, the clock in our (roughly 25 yr old) range still functions as
accurately as any in the house (including the electric which dates from
1948 when we first got grid REA power). I'm quite certain my wife would
not do w/o the auto-start feature and am even more certain she'd never
accept black. :)
What convenience? I can think of very few things you'd cook in an oven
that could sit un-refrigerated half the day before the oven turned on,
and not give you food poisoning. Timed start is a feature looking for a
problem, timed shut off does have some utility however.
Very nice. How/why did you decide on this instead of Blue Star,
Viking, or Wolf? FYI, my sister selected Wolf because she felt it
would be easier to clean than Viking (don't think she looked at Blue
Never looked at Blue Star. One reason was price. $2500 versus $4200.
Bertazzoni has a more direct distribution system, thus a lower cost. In my
case, we have propane. The serviceman for the propane says Wolf can be
difficult to get setup right. One place had a Jenn-Air on the floor that
listed for $3900. Looked like a $900 range that they tacked on some fancy
grates and big price tag.
I had never heard of the brand before, but they have been in business for
over 125 years, still family owned. They are family new to the US and I
suspect that is another reason for the price as they want to build market
share. We though tit was a good value and we really liked the styling.
Yes, they can, and do.
Haven't you noticed that even the power companies themselves (like PG&E
here) are running ad campaigns advising people to get rid of all those
"phantom" electricity users?
A guy here at UC Berkeley has done research showing that all these
things--wall warts, devices that power LEDs, etc.--use a trememdous
amount of electricity when added up.
The best argument against democracy is a five-minute
conversation with the average voter.
I don't believe ovens have had delayed start for a long time due to
safety reasons but most have cooking length timers. We use ours all of
the time mainly as a reminder when to remove the food. But it wouldn't
be a major deal if it didn't have a timer because there are lots of
inexpensive windup or electronic timers that could be substituted.
