     Like I said, they serve as the cranking battery for my generator, which is
an Onan, which takes lost of starting current so gell-cells would hardly do.
They are (now rather elderly) AGM's.  Don't remember the make.

     I don't understand why they are not more popular.

which is

Yeah, I was trying to figger that out myself...
My theory is that its the "base" - not an RV
type guy, but most RV's don't have regular
Edison (standard bulb) base sockets, do they ?
For me if was great - took a few of them clamp
on aluminum cone lights you see at HomeDepot
or the hardware store, hacked off the plugs, and
put on cigarette lighter plugs. Use em in/on/with
the truck and boat. They are just great! - love em.

$2 for a 13W 12-volt CF that draws .86 Amps @12v is bad ?
hummm.  Better go back and rethink this I guess.

No idea what this is.  I'm a DIY guy, hot glue gun, hobby battery's,
12-v CF's, old lamp sockets, miniture decoverative lamp shade...

Have you, or can you, actually measure the imput
current and voltage for one, or more,  for a sample? I,
for one, would be interested in the actual power
consumption of the inverter.

JoeSp stated:
"The 1156 incandescent draws about 2.1 amps at 12.8V
'W, and provides about
400 lumens for an efficiency of 15 lumens per watt.

An F8T5/CW Fluorescent draws about 0.8 amps at 12.8V
.2W, and provides
about 400 lumens for an efficiency of 39 lumens per
watt. That's over twice
the efficiency of incandescents"

This indicates a regular incandescent is about the same
efficiency as the 1156 at 400 lumens per watt. There
must be a typo, wordo,  or matho there.

More data needed if anybody has it please.

It's not 400 lumens per watt. Both produce 400 Lumens (brightness)
Incandescent = 15 Lumens per watt. (less efficient)
Fluorescent = 39 lumens per watt. (more efficient)
