Regarding those solar powered small lamps that are useful for outlining a
driveway: HD and Lowe's has them from several mfg's; usually in packs of 6
or 8 for around $ 30 or so. Do they really work ?

Yes, though the batties they require are lithium so cost a bit more.
replace them annually.

After a summer day soaking up sunlight, will they illuminate all evening ?
Reasonably bright ?

Depends on what you need. *They normally last til sunlight comes back but
dimmer come early morning. *They are enough to see the driveway and walk
along a sidewalk. *This isnt a main streetlight level light, but a dimmer
addition for safety.

For 30$ for 8 of them, we find them useful.

Live in New England.
What happens in the winter with considerably less sunlight ?

Here, with fewer leaves to block the light, they work a bit better.

How do they actually work ?
Just by using a solar cell to charge a capacitor, or... ?

They charge a little battery inside that you get. *AA cell type, lithium if
i recall. *Once one goes dead (doesnt light at night) first put it in full
light for a day and see if it lights that night, and if not, replace
battery.

I got a set almost 2 years ago. *All still work fine though most have had a
battery replaced.
