I would the spreader lights to anchor at night. That is about it. Even then I would be reluctant to do so.
They are so bright that using them while sailing or when getting ready to sail would affect night vision. It takes about 20 minutes to get your accustomed to the dark.
You should not use lights that could be confused for navigation lights.
