Do these have a setting to choose white vs color changing, or are the outfitted to only change color?

Sorry, this product is color-changing mode only. It doesn't come with a setting to change modes.

What size are the screws?

I don’t know the length of the screws. They are small but long enough to secure the light. I have had mine applied to the deck for a year and they are working well. Love the ambiance the lights give to the area. I have three sets for my deck. I would purchase them again and for other areas.

Does the manufacturer cover a warranty if some are bad? And how long is the warrenty coverage?

Idk but pop off cover battery is lose I had a few really like these they work good 4 money waiting 4 next sale 2 buy 2 packs 2 put on fence n deck

What type of batteries do these take?

They include batteries but are single AA type battery.
