Six years ago, I bought a remote, primitive, water access only, cabin in coastal BC. After selling my house in Portland, I carried all my stuff out on to the front yard and tried to sell it….Not really my style, but I did it.
“Noooo!. Not Grandmother’s lamp,” my sister howled. I told her she was welcome to take it, but without electricity, I couldn’t justify carting a lamp around with me and I have no room in my life for sentimentality of things. 
Now, after all these years with a headlamp strapped to my head, I have purchased a lamp and a 12 volt DC bulb to go into it. The guy at the solar shop wired up an outlet, so I can run an ordinary AC lamp off of my DC power system.
I ordered two 12 volt bulbs: one 2.4 watt 3-LED luxeon in warm yellow and a 7 watt warm florescent– in case I need more light. I got them both from Backwoods Solar. The 7 watt one lights up the whole cabin but the bulb extends past the shade and looks a little odd. The LED one, is enough to read with and looks good.
When I first plugged it in, it didn’t work. I reversed the wires on the outlet and now it does. I think I should have reversed the polarity on the lamp, if that’s possible. But I will work it all out and post a diagram and a “how to” on plugging an AC lamp into a DC system, soon.
Anyway, it’s working and it’s very cheery.
