1156 draws aprox 2.1 amps at 12.8 volts, for 27 watts.
If the cf, rated at 9 watts is only 90% efficient, it could actually
consume 10 watts. If the inverter has an overhead of 5 watts and a
conversion efficiency of 90%you are looking at 16 watts - just over
half the power consumed by the 1156.
Your lamp and inverter efficiency may vary.

Thin-lite.........that is what I put above the sink in my RV a small double
tube Thin-lite. I cant remember the exact model #. It doesn't give me the
light I want and it draws allmost the same as one 1156. At least my clamp
tells me so.

Just a note.... I put a CF in my photo sensor fixture at my back
door(against the maunfacture rules).......figured it would work fine and it
does. The photo fixture I am talking about has a relay switching method
built in. I can hear it clik.
