120v LED vs CFL vs 12v Lamps Results
Following up on another thread discussing using inverter and 120v lights with LEDs or CFLs. I have been using a CFL for a reading lamp for some years, but now have an LED bulb to make a comparison. ...

So if I understand correctly, using 120v inverter is 1.7 amps + .5 amp for 120V LED bulb?
To clarify--
The LED case of a 2.2a DC draw was:
-0.7a standing parasite draw, plus
-1.0a with 3000w inverter on (which has a small standing load doing "whole house" from the 120v power centre circuit breakers-about 0.1a DC each) making that 1.7a draw before turning on the LED reading lamp.
- 0.5a with LED on (that is not all "light bulb"--it is in a socket on a wire circuit that has some R to it--your rig's circuit might have more or less load to it as seen by the inverter than ours.)
Depending on how your wire your inverter to the batteries, what inverter you use, and and how you power your LED light from the inverter (whole house through the power centre or ?), you can get different results from mine.
It seems some of those big inverter/chargers have much more no-load DC draw with all their display "features" etc, sucking power, than my simple inverter has, so the inverter-120v reading lamp trick would be more for a simple inverter I think.
