Low voltage lighting benefits
In my extension most of the new rooms will be having the small lights
inset into the ceiling - but I don't know whether to do it with low voltage lamps or use the mains powered small lamps (Wickes currently are doing packs of 4 mains powered lamps for =A313.99). Can anybody tell me of the relative advantages/disadvantages of going low voltage or mains voltage for this lighting?

oups.com... "Can anybody tell me of the relative advantages/disadvantages of going low voltage or mains voltage for this lighting?" One of our rooms have a light fitting using 4 mains powered GU10 bulbs and I can guarantee a bulb will blow every 3 or 4 months. Surprisingly the bulbs that have lasted the longest so far are the cheap twin packs I got from Poundland! If I fitted another one I'd pay extra go for a transformer low voltage type. |

Are the LED downlighters available yet? How do they compare on
brightness and energy efficiency? I imagine that they can be fitted into the same fixture - that is they are GU10 spec. CM. |

They're both horribly inefficient at general lighting, and won't meet the building regs requirements for lighting energy efficiency if they apply to your extension (I can't remember off-hand when they kick in on a building project). The building regs may require instalation of a certain number of "low energy" light fittings as a part of the build. The number required being dictated by the number of habitable rooms you are adding. Note however that these fittings do not have to be the only fittings used... so you can make your ligting as energy inefficent as you want, so long as somewhere you can point to the required number of LE fittings to satisfy the regs. Even if the LE fittings never get used! -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

In article .com,
"Charles Middleton" writes: Are the LED downlighters available yet? How do they compare on brightness and energy efficiency? Roughly same efficieny as LV halogens. However, semi-conductors would be destroyed at typical LV halogen temperatures, so they're all much lower power, with resulting much lower light output. To make them look bright, the light is usually concentrated into a very narrow beam. I imagine that they can be fitted into the same fixture - that is they are GU10 spec. There are 7W compact fluorescents in this format now. In theory, they should give the same light as a 28W mains lamp, but that's probably reduced a bit as the tube and reflector combination is not going to be as effective as with a filament lamp, and they will be wide angle only. -- Andrew Gabriel |
