Bright Energy Efficient 3mm LEDs Whereas most lights have 10cm bulb spacing, we've designed our tree lights with 2.5cm spacing. With more bulbs per metre, they produce a super bright, sparkly, and magical display. Plus, we've used low power and energy efficient LEDs, making them low cost to run. | 8 Flash Features with Memory Function Love a bit of festive sparkle? Press the button on the transformer plug to select from 8 flash features, including twinkly effects and a static glow. For fuss-free operation, the lights have a memory chip to memorise the last setting you selected when they come back on. | Timer Function (6hrs On/18hrs Off) Remembering to turn the lights on and off need never be a problem. Thanks to a timer function, you can set them to automatically light up at a time of your choosing. Once set, they'll light up at the same time every night. Plus, they'll automatically turn off after 6 hours. | Mains Powered with 5m Cable The lights are mains powered with a UK transformer plug and 5m cable for easy placement. Although the plug is only suitable for indoors, you can display the lights outside should you wish to. A green cable makes them great for adding a festive glow to garden trees and bushes. |
