    During our night time travels across the desert... we stop frequently to rest for about an hour. Have some coffee and go over maps & compass readings.
    During this hour we have two options: ( Camp Lighting...not to light up our journey )

    1) Install an " Inverter " on the rig to use 120v clamp lights.
    OR
    2 ) Put 12v, 60watt lightbulbs in the clamp lights & change out the plugs for battery clamps.
    I have seen these lamps at RV places also...
    My question is:
    If the 60watt, ( AC-120v ) use draws 0.5amp...…..but on the Inverter and the 12v-lamp, ( DC ) draws 0.50amps. ( Considering that there would be amp draw from the Inverter even when just " idle mode " ).
    Flashlights are combersome
    Colman Lanterns break Glow Bags & need VERY flammable fuel
    Battery powered lanterns...well just get tossed around & broke.
    My main concern is vehicle " Battery Life "...?

    Our whole adventure is navigating the sometimes rough, rocky, sandy, dangerous travel by night only.
    During the day; we get needed repairs done... repack...reload... and go again for sometimes three or for days at a trip.
    I have packed in a small generator but that is just more lost space & weight.

    All ideas or thoughts would be greatly appreciated..!
    Side Note:
    We discuss this almost EVERY night someway.... :)

    Thanks,

    George

    Incandescent or florescent?

    Either way there's no free lunch-

    A 12 volt 60 watt lamp will take 5 amps, not .5.

    An inverter powering a 120 volt 60 watt light will draw around 5.5 to 6 amps from the battery depending on it's efficiency at the load you're drawing.​

    I would go with LED 12 volt lights, about 1/10th the power draw of incandescent or 1/5th of florescent for equivalent light.

    Good point...and I stand corrected..!
    Got my math screwed up....again.
    The LED idea sounds promising....
    Will do some " Garage Tests "..... :)
    We have a two-week trip planned soon coming.
    Would really be nice NOT to screw around with stuff that does not work.
    Thanks..!

    My first thought was LEDs as well. Coleman has a number of LED lanterns available. Lots of other options out there too.

    I wouldn't draw from my main Jeep battery with an inverter, unless you intend to leave the engine running? I had a small inverter in our truck while we traveled, and even that ran much better when the truck was idling.

    I have a medium inverter in my Tahoe for when the wife and I do road trips up north. Kinda nice to have the Mr. Coffee at the rest stops... :)
    As for the off road trips...looking to try decluttering of gadgets and stuff. Less to find, fix, or toss once back.
    I have two batteries I use in the rig because of the all the off road lighting at mostly idle speeds + a separate Lithium 12v for the two radios. The Lithium gets charged by a small solar panel I throw on the sand during our stop during the day.
    Just have a female socket on the body panel I plug the solar power cord into.
    Thanks..!

    I would look at something like a led cordless trouble light. I've taken my snapon one camping and it lasts all weekend on 1 battery. They usually have a hook or magnet to hang it up with and are way brighter than an incandescent bulb. Whether you convert a trouble light to clamp on the auto battery or get one thats self contained it will still be packed somewhere.
