A seriously overlooked segment of home decor, most of us just live with whatever we can get hold of whenever. Because once you get started, there are really quite a lot of things to consider. Do you want to illuminate your home in white, yellow or LED multicolour and then how bright or dim it should be. Thereafter, we may want to add a dimmer/timer switch. Just remember the bulbs have to be energy-saving.
Lots of websites with online lighting catalogs but you can only buy online with Qoo10, even 3M lists their goods there officially.
