LED light bulbs are moving into the main stream now – anyone looking for energy saving light bulbs for the home, can now choose between CFLs (compact fluorescent light bulbs) which used to be the only alternative to the old incandescent bulbs, and LEDs, the new kids on the block.
LEDs have plenty of advantages – they use much less energy even than CFLs, 30-50%more efficient; they last a whole lot longer, up to 50,000 hours as opposed to 10,000 hours, ten years of more of average use; they are far less fragile, being a solid lighting system – no delicate filaments or glass to shatter when the cat sends the lamp flying.
With regard to the cat disasters – we’ve found that the CFLs that we switched over to several years ago almost never have the life span they advertise. If the cat doesn’t knock over the lamp, scattering shards of glass and fragmenrts of mercury under the fett of kids and animals alike, then the all too frequent power surges or power outages put paid to several light bulbs each time – CFLs just don’t like extremes of temperature or being switched off and on too much. LEDs apparently are much more resilient.
The main disadvantage of LED lighting, now that the light quality is every bit as good, and often better than, CFLs, is price. LEDs still cost considerably more than CFLs. Even though LEDs work out to be the cheapest option long term, once you work out their life span and energy savings, it is still quite an initial expense to equip a whole house with LEDs. So the answer is to do your research before you buy.
While prices are coming down, it doesn’t work just to buy the cheapest brand from a supermarket shelf. As with any new technology there are cheaper, lower quality versions that don’t live up to the LED promise, and which are sure to disappoint. You need to inform yourself about the quality brands of LEDs first of all. In South Africa, some of the reliable brands available are CREE, Edison, Bridgelux and Epistar.
Next work out your requirements – do you need overhead dangling light bulbs, or spotlights, reading lamps or tube lighting. You will need to read the labels attentively to get an idea of light output, whether it is omni-directional or focussed light, warm or cool temperature. Check out this article written by a journalist trying out LEDs in his own home. The brand names available are different in SA but the choice is about as wide.
Next compare prices among the better quality brands. You will probably find they vary a lot, so find a specialist supplier that stocks the top brands at a reasonable price. Bargain basement is not a good idea when you are shopping for a product that you hope will last you 10 years or more.
One of the most reasonably priced suppliers of LED lighting in Cape Town that we’ve found is CandelaLED – they source direct from the manufacturers so are able to supply their LED light bulbs and general lighting at an affordable price. Because they specialise in LED they can also advise on the best product for each lighting situation.
And while replacing every light bulb in the house with LEDs is probably beyond the budget of the average householder, there’s no reason why you can’t commit to buying ,say, one or two LED light bulbs per month and gradually introducing a more sustainable lighting system in your home. That’s our plan at least!
