They're currently on sale for £6.50 instead of £12.99; eagle-eyed HUKD members report that it was £9.99 a few days ago, so Amazon are clearly in the mood for tinkering around with their price for this.
The Ecozone Moonlight uses a high tech LED panel so there are no bulbs to blow, break or replace.
It has some special voltage reducing something or other that means your Ecozone Moonlight nightlight to run continuously for less than 1p per week; very wallet friendly.
The LED panel is also cool to the touch so it's safe to use in children's bedrooms, it's also very light and portable making it perfect for taking away on holiday with you to gently light up unfamiliar rooms.
The Ecozone Moonlight is guaranteed for 3 years.
