Very easy to install.  The globe on this model screws into the lamp assembly which should make it easier to replace the bulb than the one this lamp replaced.  The old lamp had a set-screw to hold the globe in place and since we live on the ocean, the set screws tended to rust and jamb in place. The only possible negative of this lamp assembly is it is die cast aluminum, my old lamp had a plastic housing.  We will see how well this new one holds up in the salt air.
