Battery Powered, Copper Wire — Placement Freedom Without Cable Runs
The practical advantage of battery-powered fairy lights over mains-powered strings is placement freedom. A wine bottle centrepiece on a dining table, a cluster of lit bottles on a shelf, a vase on a mantelpiece — none of these positions have a socket nearby, and running a cable to them creates a visible wire that undermines the effect. With 3×LR44 batteries in the controller, the lights sit wherever the bottle or container sits, with no cable to manage. The copper wire is thin and flexible enough to thread through a bottle neck and coil inside the glass — the light refracts through the glass and creates a glow from within the container rather than from a visible light source. The waterproof construction means the same string works outdoors on a terrace table or in a garden lantern without any additional protection. Browse the full Fairy & Festoon Lights collection.
The 7 colour options cover the full range of event and interior uses: Warm White and White for neutral, versatile settings; Green, Blue, Red, and Lilac for themed events and seasonal decoration; RGB for colour-changing effect. Choose the length based on the container: 10 LEDs/1m suits a standard wine bottle or small vase; 15 LEDs/1.5m suits a taller bottle or medium vase; 20 LEDs/2m suits a large vase, lantern, or multi-bottle cluster.

Common questions
Which size should I choose for a standard wine bottle?
+
For a standard 75cl wine bottle (approximately 30 cm tall), the 10 LEDs/1m string fills the bottle comfortably with enough wire to coil inside the body. The 15 LEDs/1.5m string gives a denser fill or suits a taller bottle (Champagne magnum, 1.5L). The 20 LEDs/2m string is better suited to a large vase, lantern, or a cluster of two or three bottles wired together.
How long do the batteries last?
+
Battery life depends on the number of LEDs and how long the lights run each day. With 3×LR44 batteries and the 10 LED string, expect approximately 40–60 hours of continuous use. For event use (4–6 hours per evening), a fresh set of batteries will last several evenings. LR44 batteries are widely available in supermarkets and hardware stores.
Can I use these outdoors?
+
Yes — the waterproof construction makes these suitable for outdoor use in rain and damp conditions. For outdoor table centrepieces, garden lanterns, and terrace decoration, they work without any additional protection. Keep the battery compartment facing upward or sheltered if possible in heavy rain to extend battery life.
Does the RGB option change colour automatically?
+
Yes — the RGB variant cycles through multiple colours automatically. It is not remote-controlled or app-controlled; the colour change is built into the LED sequence. If you prefer a fixed colour, choose one of the single-colour options (Warm White, White, Green, Blue, Red, or Lilac).
Can I thread these through a bottle neck without damaging the wire?
+
Yes — the copper wire is specifically designed to be thin and flexible for this purpose. Feed the LED end through the bottle neck first, then gently coil the wire inside the bottle. The battery controller sits outside the bottle at the neck. Avoid sharp bends at the same point repeatedly, as this can weaken the wire over time.
