Superb and useful / energy saving LED lighting set. Light where you need it in hallways, garage, shed, attic/loft, cupboards, bookshelves, under kitchen or bathroom units, caravans etc. Each unit has 5 bright white SMD (Surface Mounted Device) LED’s which are around 20% cheaper to run than standard LED’s. Flat LED\'s give a wide beam angle and a diffused and even spread of light - incredibly bright too!. Comes with a 4 button remote control unit (works 5 to 10m away). Remote unit measures L8xW6xD2cm and has a handy wall bracket included. Remote works all 3 lights at the same time providing they are within range. The remote will also work each unit individually where the other units are somewhere else - so the lights can be used in different rooms / independently. Remote requires 2x AAA batteries and each unit needs 3x AAA batteries (not included). Light unit measures 9.4cm in diameter and is 3cm in depth. Twists off back to reveal the battery compartment. Units can be mounted on ceilings or walls using the included double sided pads or screw into place using the holes on the back plate.
