Most options use the standard Edison medium screw base (E26). Some fixtures, however, list non-removable integrated LEDs rather than a replaceable bulb.
Many listings show a warm 2700 K color temperature. Lumen outputs vary by model, typically ranging from about 415 lumens up to around 800 lumens depending on the bulb.
Listed lifespans vary across items and use different units. Examples from the listings include values expressed in years (e.g., 1.4 years, 13.7 years, 22.8 years) and in hours (one night-light is listed at 30,000 hours). Note that some products report life in years while others use hours.
Some items are marked as UL Listed. Other products explicitly state they have no certifications or are not listed/certified.
Dimensions vary by item. Example listings include a pendant at 19.25" H x 27" W x 27" D, a pendant at 114" H x 15.25" W x 15.25" D, and vine curtain lights described as 5 ft x 3.5 ft.
