50 Bright Warm White LED Blossom Bulbs 5 Metre Lit Length 6 Hour Timer Function Fully Waterproof Steady & Twinkle Settings Great value LED battery operated blossom fairy lights. This set features 50 bright warm white LED blossom bulbs on a 5 metre green cable, waterproof battery box, twinkle/steady setting & a timer function. Ideal for outdoor trees, bushes, hedges, decking & for all events: including bbq&0s, weddings, Christmas, parties & festivals. We almost forgot...of course you can use them indoor as well! The plastic battery pack is both robust & waterproof ensuring the batteries, function switch & timer survive all that the British weather can throw at it. When the lights are set to the timer function via a switch on the battery box they will stay lit for 6 hours. After being lit for 6 hours they will turn off for the next 18 hours & then come on again. This is brilliant for two reasons, firstly it saves you having to remember to switch your beautiful lights on/off every night & secondly it conserves the battery life. The battery lights take 3 x &0AA&0 type batteries (not provided). The blossom caps are also supplied but will need to be inserted onto each bulb. So to sum up... you can have the ultra bright led lights you&0ve always wanted but with no need for an outdoor socket & as a bonus you can have them twinkling & set on a timer function.
