TOP! Exceptionally 5 * (even by me)

All expectations were met with Duracell.
The beam covers the entire table, except for a small radius around the base.

2.): Although not with candlelight / bulb comparable, but pleasant.
At 3): They can be infinitely adjusted down so far that it is even suitable as a night light. The Dimmregler simultaneously serves as an on / off switch.
To 4.): Not too small, not too big, easy, but not cheap-acting
5.): high-quality plastic (otherwise it would be difficult)

The Duracell is very bright, so that it is bright enough to light up a big tent from. (I know, too, is subjective. ;-))
A charge has held three weeks but was now not very used in summer because of the late twilight and in the caravan, and home by the patio table.

Tip: Have the three baby cells replaced by adapter, with which I can use 3 x 2 AA batteries. (Of course, "Eneloop")
They are easy to charge by many compact chargers and bring 4000 mAh / adapter (baby cell)
