I am remodeling my home and have a very serviceable light fixture. Would Matthew Ministries be able to use?

They take everything..

I would call them directly.

They don't take lights, as far as I know. Habitat for humanity restore would.

Call them to ask. Its possible they might use it in their big warehouse where they do the Christmas party for special needs kids & families. If not then habitat for humanity.

Habitat for humanity has a store. If Matthew 25 Ministries can't use the light call Habitat.
