Outside fixture use

The bulbs are not rated for outdoor use because they are not sealed and rely on airflow to cool themselves. If you put them somewhere that is sealed then they may heat up too much to operate, and if you leave them unsealed then they can build up precipitation which can kill the electronics.

If you can find a way to deal with both those issues then you might be successful. As you said though we don’t recommend operating the bulbs in outside fixtures, and we cant recommend it.
