Some fixtures use standard replaceable bulbs with E12 candelabra or E26 medium screw bases (bulbs often not included), while others have integrated, non-removable LED modules.
Many listings are rated for wet/outdoor use; common examples include ETL listing for wet locations and IP65 waterproof/weatherproof ratings.
Common options include dusk-to-dawn photocell sensors, motion-activated sensors, and fixtures with remote or smartphone app control. Some models combine motion sensing with automatic dusk-to-dawn operation.
Dimensions vary: compact fixtures can be about 6.9 inches high by 3.1 inches wide, while larger lantern-style fixtures reach roughly 19.7 inches high by 7.1 inches wide, with multiple sizes between those extremes.
Many listings are hardwired—several state “Requires Hardwired Installation: Yes.” One solar security-style fixture is designed to operate without wiring and installs using its solar power system.
Some smart fixtures offer remote and smartphone app control for brightness and color. At least one security-style fixture lists full-range dimming, and several models use motion sensors to change brightness when activity is detected.
