Entryway Fixtures
Remember to use the right size bulb for these kind of fixtures. If the bulb extends below the bottom of the fixture, the fixture is no longer "fully shielded."
Path and Landscape Fixtures
While some uplighting is permitted under Nantucket's outdoor lighting bylaw, the most dark-sky and neighbor friendly fixture is fully shielded.
Patio/Garden String Lights
Fully shielded are the most dark-sky and neighbor friendly. The limit on unshielded string lights, all bulbs combined, is 2000 lumens for residential properties and 4000 lumens for nonresidential properties, and the brightness can't exceed 50 lumens per linear foot.
Svater Globe String Lights (28 lumens per linear foot)

Floodlights
If your floodlight has an exposed bulb, it may be possible to add a shield to convert it to a fully shielded fixture. However, keep in mind that the fixture would have to be pointed down to be considered fully shielded.
