With this fantastic item, you're never left in the dark... When the power fails in a power cut, the re-chargeable internal battery in Safe T Light takes over and automatically illuminates the torch... As the only light in the dark, the torch head is easily located and can then be lifted from the base unit. You now have a torch that will last up to 4 hours. No scrabbling around in drawers or falling on the stairs in the dark looking for candles or batteries.. But thats not all... it is also an Economical Night Light gently illuminating your stairs, hallway, landing or your bedroom, the unit is consuming less than 0.5 watt of power and is the ONLY product of its type to achieve the prestigious ERP Eco Design Directive Phase 2 Award... This is far more economical than any other emergency light on the market or conventional 7 watt night lights, in real terms it will cost less than 50pence per year to power this item.... a tenth of its next nearest rival... The recommended positioning of a SafeTLight should be near stairs, on landings and optionally for the young or elderly, in bedrooms. Did you know that falling down stairs in the dark is a common source of injury for the elderly and our SafeTLight is leap forward in safety in the home. Also Great for Caravans, Boats, Sheds, & Garages and makes a perfect gift for that difficult to buy for "someone who has everything" we all know....!!!
