John Lewis & Partners 240 LED Firecracker Lights, Pure White, 10.7m

A string of energy efficient LED bulbs on a fine, flexible copper or silver wire.

Each of the LED bulbs is topped with a cap that gives the light a flickering, candle-like effect.

With 8m of wire between the transformer and the first bulb, the 240 LED bulbs are spaced 5cm apart, making them suitable for a 4ft to 6ft tall tree.

When the low voltage transformer is located inside, the design of the wire makes these lights suitable for indoor or outdoor use.

• Consume up to 90% less power than incandescent bulbs
• Long LED lifespan
