Is 1500 lumens bright enough for a driveway?

It is bright enough to light a porch, doorway or small driveway area. For a large open driveway, expect it to cover a limited zone rather than the whole space.

Can it be mounted in direct rain?

IP54 means it is protected against dust and splashing water, not water jets or heavy soaking. Mount it under an eave or overhang where possible.

Does the motion sensor work in daylight?

Most motion sensor lights of this type only switch on when it is dark, so they stay off in daylight. Check the listing for a dusk-to-dawn or sensitivity setting if that matters to you.

What is included in the box?

Expect the light fixture and mounting hardware. Bulbs are not needed because the LEDs are built in.

Can the light head be aimed separately from the sensor?

The 360-degree adjustable head lets you point the light where you want it. The sensor's field of view may not follow the head, so aim the sensor toward the approach path.
