How Thomas Edison would smile upon the likes of Ryness, which sells everything you’ve ever needed in a bulb or with a filament. Light bulbs, LEDs, energy savers or any other general household lighting requirement you can think of. They also offer a useful range of electrical appliances like vacuum cleaners, bedside lamps, heaters, kettles and toasters. You’ll even find the odd, cheesy disco light and a few computer peripherals. The store itself provides a lot of eye candy and probably uses enough power to light a rural settlement of computer hackers bent on world domination. Still, at least you can help Earth’s plight by upgrading your home’s lights to energy savers, which are available in every shape and colour for a really good price.
