These indoor and outdoor battery festoon lights feature a new and improved design, with a higher quality construction and brighter LEDs. They're perfect for adding soft, ambient, decorative lighting to your home, garden or event and, thanks to being battery-powered, they're great in places that are hard to reach with mains power. These lights are so easy to install since the battery box comes complete with a pre-mounted hook. There's also a handy timer function which allows you to leave the lights switched on: they'll stay lit for six hours, before turning off for eighteen hours and then turning back on at the same time as the previous day, it's that easy! This is brilliant for two reasons, firstly it saves you having to remember to switch your beautiful lights on/off every night and, and secondly, it conserves the battery life. If you want your lights to stay on for longer, simply set the switch to the On position and turn off when required. This set has 10 waterproof, golf ball sized frosted bulb caps, placed 50cm apart on a black cable. Each globe measures 5cm in diameter, contains a single warm white LED bulb. The 10 bulbs are fitted along a set 4.5m length and are not connectable. Please note: to switch the lights on, press the 'ON' button for 3 seconds. Press the 'ON' button again to engage the timer function - the LEDs will flash on and off 5 times to let you know the timer function has been activated. Requires 3 x AA batteries (not included).
