Product review (4 stars): Glad I did not pay the list price!
Yes, the clock is a 24 hour mode only!
You can not change it!
Led lights are worthless except for a night light.
They are very dim and are blue in color.

Fan works great, Overall it looks great.
Easy to put up, but I used lag-bolts not
the plastic anchors provided.

I can live with it.
