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.....

PS If anyone is interested, I can Email you
the schematic.....


What I am interested in is... What's the company name of the dollar
store where you got them?
Is it "Dollar Store" or some other cheap price store like 'Family Dollar
Store', 'Dollar Tree', 'Dollar General', or some other name?
