How much power does a 120v 15A lighted switch use anyway?
 
Just bought a dozen Leviton decora single pole 15A 120VAC lighted rocker
switches (model 5611, aka model 105-05611-21S).

Nothing on the box says how much power each of the lighted bulb uses when
the switch is in the off position.

Do you know how much power a lighted switch uses?

About as much as a 110 volt neon bulb. I'm sure you can find specs
for those a lot of places. But it's very little, just a guess 0.01 to
0.1 watts? Let me know what you find out.

I have had a lighted switch at my day job. It had a high intensity neon
lamp, apparently either C2A (NE-2H) or A1C ("mini NE-2H) (hard to tell
through the switch). Figure about 1/4 watt.

A neon uses about 0.15KWH a year.


I had experience with a lighted switch at my day job. The neon lamp was
definitely a high intensity type, probably C2A (NE-2H) or A1C ("mini
NE-2H").

Figure about 1/4 watt for those, which means around 2.2 KWH per year
times 1/100 of the percentage of the time that the neon lamp is on.

That is, until the neon lamp starts flickering (uses less then) after
25,000-50,000 hours. High intensity neon lamps in 120 VAC use tend to
flicker and then gradually completely die as they age. Standard intensity
ones do less of that and more of simply fading from their bulbs being
discolored.

This would be about 9 cents a year, if the light is off all year.

It is negligible regardless what's in there, neon or LED.

You are correct. And if I am not mistaken you get more lumen/watt from

then neon.

It's likely either an NE2 or an NE2H, which a quick web search shows
are rated for .03W and .09W, respectively. The right answer is

Our utility prices are 11 cents (¢) per kilowatt (KW) for the first KW of
the month but 48¢ for the last two or three weeks' worth of kilowatts. I
would guess the average KW out here to then be about 35¢.

So, if I add a dozen of these lighted switches, and they're on most of the
day, say, 20 hours per day for 30 days in a month, at .096 watts per hour,
that comes to about a penny per day, I think.

12switches x 20hours/day x 30days/month x 0.1watts x 35¢/KW x 1KW/1000W =
25¢/month

Using California electric rates, I get, for a single switch, 31¢/year?

1switch x 24hours/day x365days/year x 35¢/KW x .1W x 1KW/1000W

We have tiered pricing out here where the first week or so costs about
11¢/KW, the next week is about double, and the last two weeks of the month
it's more than 4 times as much so I averaged that to about 35¢/KW.

I don't understand the 1/100th the percentage (figure 98% of the time the
switch is off so the neon bulb is on).

What's the 1/100 for?

It looks like it's costing 25¢/month for the dozen neon-lit switches.

What noise would I be worried about? I have the normal stuff (phones,

Using 0.1W, and averaging my electric rates (35¢/KW) for a dozen switches I
get about 25¢/month or $3.00/year.

Yes.

At ten cents per k.watt.hr


The only "problem" is that our energy here in sunny California is nowhere
near 10¢ per KWh. I'm going to get my bill and come back with the actual
numbers, but the first KWh is about 12¢ but that only lasts for a
"baseline" which is about a week. Then the next week is double, then
triple, then more than four times that when you get to the last week.

I'm figuring easily that it's 35¢/KWh here in California. Any other
Californians out there that can help me on the math?

My math comes to about $3.00/year for the dozen switches.

You guys have cheap electricity!

I just pulled out my California PG&E bill to check the numbers (I can't
believe you guys pay only a dime per Kwh!!!!!. Lucky you!)

My baseline is 365.4Kwh at 12¢/Kwh
Then for 101% to 130% of baseline, it's 14¢/Kwh.
For 131% to 200%, it's 29¢/Kwh.
And, for the last few weeks of the month, at 201% to 300% of baseline, it's
43¢/month.

I averaged this to about 35¢/Kwh because I didn't know how to do the math
otherwise (I used over 150 Kwh at the 131% to 200% rate and 256 Kwh at the
29¢ rate).

..1W/bulb x 12switches x 20hours/day x 365days/year x 35¢/Kwh x 1Kwh/1000KW
= $3.00/year

It would be nice to see what others pay for 201% to 300% over baseline 'cuz
if it's 10¢, you have the deal of the century!

Interesting observation. I know that when a single lead from a
neon light touches a hot wire, the neon light will glow if there
is almost anything touching the other lead. Was used as a voltage
checker long before the IC devices were available. If the neon's
lead was touching a hot wire and the other a ground/neutral, then
the lamp glowed brightly, otherwise, there was a lesser glow.

This leads me to the conclusion that neon lighted switches take
advantage of this ability and do NOT require a lead to ground or
neutral to achieve the low level glow seen in a lighted switch.
Perhaps an LED lighted switch would require a grounded/neutral
other lead to work, together with diode to convert the AC to DC.

Well in the UK we pay around $0.25/Kwh. Plus a fixed "meter rental".
Massive rises forecast for the near future. To pay for our
replacement nuclear power stations.
The upside is our electrical appliances are more efficient.v They
need to be.

My electricity bill is about $100/month on average. However I have no
gas/oil bill my house is zero heat needed.

in our area, the rate during the day is 2x the rate for nighttime or
weekends, so we try to schedule our heavy usage for off peak. nighttime
rates are in the .07kwh range.

i run a couple of kilns, at about 8kh each, which can run for 2-3 days
straight, so i couldn't afford to live in ca.

however, i just installed a 7.5kw pv cell array, so my day costs are 0.

I have had a lighted switch at my day job. It had a high intensity neon
lamp, apparently either C2A (NE-2H) or A1C ("mini NE-2H) (hard to tell

- Don Klipstein )



I got my number from the 1 meg ohm resistor your typical neon has in
series with the bulb. Consider an ionized neon as a dead short.


I don't think so. IIRC an ionized neon bulb requires about 60 volts
across it, close to half of a 120 volt line voltage.

And I don't think the "typical" series resistor is 1 meg. 50K to 100K is
more like it.

otherwise (I used over 150 Kwh at the 131% to 200% rate and 256 Kwh at the
29¢ rate).

.1W/bulb x 12switches x 20hours/day x 365days/year x 35¢/Kwh x 1Kwh/1000KW
= $3.00/year

It would be nice to see what others pay for 201% to 300% over baseline 'cuz
if it's 10¢, you have the deal of the century!

more lumen/watt from led then neon.


It looks like it's costing 25¢/month for the dozen neon-lit switches.

What noise would I be worried about? I have the normal stuff (phones,
computer, router, etc.) Which would the neon affect and how?


AM radio, close to the lamp tuned to a very weak station, maybe.

BTW, I didn't see ANY LED illuminated switches at ACE or OSH in town! :(

What is a wall wart?


Power supply (AC or DC) that plugs into the wall and has a cord that
attaches to an electronic gadget. It's a bump on the wall, hence
"wall wart".

I don't understand the 1/100th the percentage (figure 98% of the time the
switch is off so the neon bulb is on).

What's the 1/100 for?


Yeah, Don, what's up with that? Nothing more annoying than unexplained
"adjustments" like that.

You guys have cheap electricity!

I just pulled out my California PG&E bill to check the numbers (I
can't believe you guys pay only a dime per Kwh!!!!!. Lucky you!)

My baseline is 365.4Kwh at 12¢/Kwh
Then for 101% to 130% of baseline, it's 14¢/Kwh.
For 131% to 200%, it's 29¢/Kwh.
And, for the last few weeks of the month, at 201% to 300% of
baseline, it's 43¢/month.

I averaged this to about 35¢/Kwh because I didn't know how to do the
math otherwise (I used over 150 Kwh at the 131% to 200% rate and 256

It's gonna get more expensive soon. Arizona provides about 30% of
California's power, and Arizona is ****ed.

So you use up your monthly baseline allocation in a week? Maybe try a
little conservation, that's the idea. And you're worried about a damn
neon bulb?

Using 0.1W, and averaging my electric rates (35¢/KW) for a dozen switches I
get about 25¢/month or $3.00/year.


Ok on all those numbers but the spec I found showed each neon
indicator using about 0.04 watts per hour.

Based on 0.3 milliamps at 115 volts. Thus wattage = current times
voltage or (0.3 x 115)/1000 = 0.0345 watts per hour.

Per month that would be 24 x30 x 0.0345 = 24.84 watt/hours.

And at ten cents per 1000 watt hours (i.e. per kilowatt/hour) that'd
cost 24.84/1000 x $0.1 = approx 0.25 cents
At 35 cents per kilowatt hour it would be 0.75 cents, per month.
And for a dozen switches 0.75 x 12 = about 3 cents or of the order of
36 cents per year.
Since we are all presuming, it seems, that the indicator light inside
the switches will be off whenever whatever the switch controls is 'on'
the indicators will cost even less than that. In other words if one is
using electric lights, negligible!

there is NO significant RF noise radiated or conducted at all from a
tiny NE-2 neon lamp..
Note, we are NOT talking about neon store window signs that operate at
25kV.

There *is* noise caused by the neon firing. Whether you think it is
significant or not is simply a judgment.

Just a nitpick, but .04 watts per hour is meaningless. It's .04 watt-
hours per hour, or just .04 watts. One watt for one hour is defined
to be one watt-hour.

Based on 0.3 milliamps at 115 volts. Thus wattage = current times
voltage or (0.3 x 115)/1000 = 0.0345 watts per hour.


No, it's .04 watts (if that's the number). You can't do some
arithmetic, throwing away precision, and then come back to the same
units with a different number. In this case you lost energy. At
least you could have made a perpetual motion machine. ;-)

Per month that would be 24 x30 x 0.0345 = 24.84 watt/hours.

And at ten cents per 1000 watt hours (i.e. per kilowatt/hour) that'd
cost 24.84/1000 x $0.1 = approx 0.25 cents

If one is using other appliances, such as refrigerators, water
heaters, or clothes dryers, the lights themselves are (usually)
negligible (if not, the whole bill is ;-).
