I have an inverter which is 65 Watts connected to a 12V 7 A-H
battery.  I plug in a light which is a compact fluorescent at 15
Watts, and it draws 1A, which I think is too much.  Is there something
I can do to reduce this, or perhaps anyone know of a great desk lamp
which doesn't draw such amount of wattage? Perhaps, connect the light
directly to the battery?

thx

A 15 Watt load will draw slightly more than 1 Amp at 12 Vdc. This is
BEFORE any loses in the Inverter.

Math: P/V=A     15 Watts Divided by 12 Volts = 1.25 Amps...

 Yes, your correct.  I learn that formula in the 5th grade, but the
question was is there a way to reduce the wattage.

and still use the 15 Watt CFL?????  Watts are watts, Sonny...
Now if your really asking how you can get the same Lumen Output
with from less Watts... then just ASK that.... or Google it up
yourself, and see if maybe LED's might do.....

 Sometimes Old Man, there are many times in our lives we don't know how
to ask a question for we don't know the vocabulary.  No way God made
me perfect.  Oh, and keep in mind we are using Google NOW to look up
stuff.....
