Bottle-style lights use several control styles: base push buttons, rotary base knobs (including 3-way control), inline cord rocker switches, and cordless models that advertise smooth dimmable brightness settings.
Use ratings vary by model: some bottle-style string lights and novelty lights are rated for indoor or sheltered outdoor use, while many table lamps and decorative bottle lights are intended for indoor/dry locations only.
Some bottle light sets include accessories such as bulbs or spare parts—for example, two LED bulbs with a two-lamp set or replacement bulbs and spare fuses with string-light sets—while other lamps explicitly note that bulbs are not included.
