How long does it run on a full charge?

The listing claims up to 12 hours, or 5 to 16 hours depending on color and mode. Expect less in winter or after cloudy days, since charging takes over 8 hours of good sun.

No. The light and panel connect by a 4.66 m cable, and the light mounts with the included screws. You only need a spot where the panel gets direct sun.

Can I set one color and leave it?

Yes. Use the remote to lock a single color instead of the automatic cycle. The 8-step timer can also switch it on and off on a schedule.

Is it bright enough for security?

It is a 50W flood light, so it lights a yard or driveway, but the colored modes are decorative. For motion-triggered security, a white-light flood with a PIR sensor is a better fit.

Can the battery be replaced?

The lithium battery is built in and not designed to be swapped by the user. When it wears out, the whole unit has to be replaced.

How far does the remote work?

The listing says over 12 m, but it needs a clear line of sight. Walls and thick foliage cut the range.
