Low Voltage Lighting is the Future of Domestic Lighting

If you haven’t heard of low voltage   lighting  before, you must have been living under a rock or something. First of all because it isn’t really a  new  thing. Halogen  light  systems for domestic  lighting  have been around for decades and you may in fact have one at home. Granted, there are varieties that run on mains voltages, but most do not. Instead, the run on 12v or thereabouts from a low voltage  lighting  transformer installed somewhere in your home. Secondly, there is so much talk all the time about  LED   technology  taking over more and more of our  lighting  needs, that it would be very difficult indeed not to have noticed. But if all this is  new  to you, don’t worry. I will get you up to speed with this article.

First a few words on what low voltage  lighting  can do for you. There are two big advantages that most people will be interested in, and these are the often much lower power consumption possible with halogen and  LED . The other big thing is that often these  light-sources  are physically a lot more compact than most people are used to. This means that an entirely  new  horizon is opening up in  lighting  design, one that allows useful  lighting  solutions to take on completely  new  and compact shapes. A desk lamp no longer has to be a big clumsy thing in order to properly contain a lightbulb and provide enough shading to keep the  light  out of your eyes and onto your desk. A  light-source  like  LED  weighs a lot less than a traditional bulb and is a lot smaller, meaning that it can make do with a smaller assembly to give you the  light  you need. This is also true for halogen  lights , but again, these have been around for years, so you may already have discovered their advantages.

One problem with the  new   technology  is the fact that it still has to live alongside traditional mains voltage  lighting . I expect that not very many people have low voltages like 12v coming out of their wall outlets at home, and this means that every time you want to use something like  LED , you must have a transformer between mains and the  LED . The problem with that, apart from the fact that transformers cost money, are heavy and take up a little space, is the fact that is always a certain percentage of electrical power lost in the transformer. This power never reaches the  LED  or halogen bulb, but is dissipated as heat. You get no  light  from that power then. If you have a lot of low voltage  led   lighting  or other type in your home then, you will also have a lot of transformers, all of them wasting a bit of power as heat. This is still less compared to the old-fashioned incandescent bulbs, but I foresee a future where it will be common to have a single, central low voltage transformer in your home, along with special outlets that carry both the traditional mains voltage along with, say, 12v. This will make lighting fixtures and also consumer electronics a lot cheaper, since they can then be sold without their own mains voltage adapters. But that is all in the future. Right now, you can have your domestic lighting updated to something a lot more sophisticated and sleek, while making a difference on your electrical bill – and the environment as well. Not bad, eh?
