I recently bought some blue LED nite lights from our local
Dollar Store ( for $1 USD each ) and find that , while they don't
give out as much light as the 5 or 7 watt nitelights I have been
using, they are perfectly adequate for keeping me from
stumping my toe on the dresser on the way to the
bathroom at 2 am......
They are advertised to draw only 0.4 watts ... That would
mean if plugged in 24 hours a day, they would cost me only
35 cents a year ( 10 cents per kwh ) . I kind of like that...
So I took one apart and made a schematic. The
limiting is done by a series capacitor.... I then fed the
network into a PSPICE simulator and checked out the
claim..... Truly, it uses only 0.4 watts of real power.....
I went back and bought a sackfull..... If anyone else has
experience with these items, please post your experience....
Sure, the light is weird ( kind of cool, actually ) and it is
only useful if you have been in a dark room for a few minutes,
but that is nomally the case for our household.....

Can't find a link for the darn luminescent night light we have had going
for more than 20 years. It is a 2" diameter flat disc in a very thin
housing that glows blueish/tealish at night. The info on it is
Intermatic Inc, GN GOOD NITE LITE, E 187141, Model GN141, UL listed 8G25
and ML-003, Made in Taiwan.
Han, I have seen those electroluminscent lights... The blue LED
puts out a lot more light.... If you like your electros, you would
LOVE the blue LEDs..... I don't know the power your electro uses,
but I'm sure it is quite small.... I have used that technology for
backlighting displays in the past..... I found that they are great
for marking a place on the wall, but don't put a lot of light out
into the room to avoid stepping on the grandaughter's roller skate
in the middle of the hallway... ....
Thanks for the reply.

Des, I'm pretty sure that Han's wife made him put the light in
so he could have better aim at night, and not wake her up
by turning on the bathroom light......
Been there, done that... :>)))))

LEDs built into kitchen and bathroom faucets are way cooler than lighted
=======Another innovative design of kitchen faucet that has illuminated LED

different colors....----- a rainbow of cleanliness,....
a caucophony of toilet potpourri....?????. If it ever gets to
the Dollar Tree, I'll buy one !!!

Not claiming you should have bought LED versions back then just
mentioning that I saw poor results with the devices you mentioned. And
come to think of it they are gone from the various other places I have
seen them being used.
Yours seems to be a lot like that light bulb in the NYC firehouse that
has been burning for the last 89 years (or whatever).
A small capacitor will have a very high resistance (Impedance) at 60
Hz, so it is effective. The LED probably only needs about 50 - 100
milliamperes, and no power is lost in the capacitor, so everything

Yeah.. It seems that the power factor shift ( around 80 deg from
but don't hold me to it ) means that the power is reactive, and
register on the TXU meter..... That's how I figured it ...
