Is that a question???
Yes, just make sure you match the plug. As with anything electrical, if it has a ground then use for safety.
Check with Home Depot. Most of the time the replacement lens is more than a new light.
This must be hard wired by an electrician.
No, this is not a sealed unit nor is it rated for outside.
Lamp was shipped to the store broken. I was told about it on email. Email offered the option to inspect at store and see if it was ok as is. When I went to the store, the lamp wasn't there and was told that it was returned and another one was re-ordered. I just wished that I was told about this re-ordering so I didn't have to go to the store a second time.
If you do not like the lens, then remove it.
