Lighting question...how much is a 5 LED 4.5v battery spotlight?

Last year we made the mistake of running an extension cord to the coop with a small floodlight and the hens knocked it down and created a fire.

This year, no electricity...have no desire to ground wire.

Just bought a set of 4, AAA battery powered muli-use spotlight lamps for gazebos, etc.

Each lamp has 5 bright white LEDs, and uses 3 AAA batteries (total of 4.5 v) per lamp.

One lamp looks pretty bright in a dark closet, could read a newspaper from it, although dimmer for my eyes.

Would one be enough for a coop that has I'm guessing has about 25 square feet total (has a top story prefab coop of 11.25 pre-fab sitting on a 4 x 5 x 1 1/2 foot floor/nest box base).

Birds nest on the poles of the pre-fab, and I would hang the LED on the ceiling rafter.

One or two lamps be enough? (Trying not to needlessly burn through AAA's).

The purpose is merely to get enough lighting so the chickens continue to lay well during the winter.

I'm not worried about any heating as we live where the winters are generally mild enough.
