Re: LED Lighting for a Standard House ? 25Jan 04, 2013 12:01 pm MR2 ohh! right fingers crossed! I figured they say hot water takes 30% or more of your electricity costs and the solar HW will save about 80% of this. So ... using my wattage, lumens, LED math skills I worked that out to be about 25% of the overall bill. Re: LED Lighting for a Standard House ? 27Jan 04, 2013 8:19 pm Danois I see you're sorted now! Sure ... Its an unbelievable subject. AND - no-one really seems to have a clear answer. Even all my calculators don't give the right answers for all of the available lights. But- LED is more efficient than halogen, and halogen is more efficient than incandescent. Thats a good start ... Re: LED Lighting for a Standard House ? 28Jan 04, 2013 8:22 pm it's funny you know, this is such a huge topic and there are so many parts to it, no one forum in Australia really seems to be cornering all the various ins and outs of solar, Whirlpool are good but there are really very few subtopics to make it easier to find specific questions etc... we have eco-living and then creative lighting...so you get a spread of everything between the two Slooowwwwly getting a Manhatten 35 in Middleton Grange Re: LED Lighting for a Standard House ? 29Jan 04, 2013 8:26 pm There might be a fortune in someone coming out with a "standard" LED downlight kit - with the equivalent markings on it and in cool or warm varieties. But - they do have solar outside LEDs don't they. Re: LED Lighting for a Standard House ? 30Jan 04, 2013 8:30 pm well, they are all pretty standard really, they all have a transformer and they all connect that to 240v, just getting the LED guys to tell you what reasonably priced dimmer works is really the trick bit... not sure where you are but Beacon lighting here in NSW demo something like 30 LED lights in their shop so you can go and have a gander Slooowwwwly getting a Manhatten 35 in Middleton Grange Re: LED Lighting for a Standard House ? 31Jan 04, 2013 8:34 pm Yep - Beacon are on my list - thanks. They are at the upper price range though. Re: LED Lighting for a Standard House ? 32Jan 04, 2013 8:36 pm yeahhhhhhh we got that too! but atleast you should be able to get an idea looking through all that they have what direction you want to go (so what colours and brightness etc) Slooowwwwly getting a Manhatten 35 in Middleton Grange Re: LED Lighting for a Standard House ? 33Jan 10, 2013 8:16 am Another interesting issue. When you have dimmers. We are planning to split the house with lights (sets) - ie lounge x 4, dining x 4 etc etc. So if they are dimming ones - you need the right driver and globe etc. Many new globes are dimmable I gather. BUT - you apparently need a dimming unit for each "set" so as they are connected together and then to the switch. So if you have 5 sets in the house (lounge, dining, etc) you also need 5 of these units too. Any comments on this ? Re: LED Lighting for a Standard House ? 34Jan 10, 2013 8:24 am What you said is exactly as I understand it as well, there are quite a few types of Dimmers so make sure you get the right one for the LED's your using Slooowwwwly getting a Manhatten 35 in Middleton Grange Re: LED Lighting for a Standard House ? 35Jan 10, 2013 8:27 am MR2 What you said is exactly as I understand it as well, there are quite a few types of Dimmers so make sure you get the right one for the LED's your using Can't believe I'm giving advice on LED lighting ... I guess free advice is worth what you pay for it ... Some dealers have not even mentioned these units. Amazing !!! Re: LED Lighting for a Standard House ? 36Jan 10, 2013 8:41 am Well, you have two issues there, I don't know why but most sales people seem to have very little idea of what they are selling (or more, very little technical information) also Dimmers are not required, more a suggestion or creature comfort... I can't find it but there was a story saying that shoppers are now preferring to get information over asking the sales staff edit: http://www.smh.com.au/small-business/ma ... 2cfm6.html Sums it up pretty well.

After much research I find I have more information - but not necessarily the "right" answers. I don't think you can go too wrong, but its worth thinking about the subject before just rushing in and spending a fortune on LED downlight kits. "Yes the numbers, wattage, lumens, height, throw, ratio is interesting. None of them on their own are a real guide. The wrong angle can ruin the right lumens etc. Clearly the sharper the angle the less wattage is needed as the "spot" of light will be stronger where it hits - for the correct height - BUT - smaller angles might mean more lights needed - while a greater angle might mean less "light" where you need it. The higher the ceiling the sharper the angle may be needed as the light loses intensity too from a wider angle as it travels (its "throw"). So more wattage may be needed. The lower the ceiling the opposite. A 2.5/2.6m ceiling could be considered high I guess ? So - maybe 9w globe w/- 60 (90?) degree angles are best - but you might need more to cover the area ? But - what about a 15/16w w/- say - a 120 degree angle - throwing out 1200 lumens. In the kitchen your bench is about 900mm high ? Your work bench. If you had 3 x 120 degree, 1200 lumen, 15 watt lights above such a bench it would seem to be OK ? The light is only about 1.6m above the bench so the throw is not that far. Then - what about colour. If you take "warm" you're losing "light". While neutral might be "harsher" it might be a better option ? In a new house where people love light for example. Not for a house where you want to "hide" things. I guess you can just have a go and change the globes in the spots where you were wrong. Making sure of course your infrastructure can handle the new globes ... " Re: LED Lighting for a Standard House ? 39Jan 13, 2013 10:19 am There is no simple answer and no standard kit is going to work for everyone as you have figured out St Mike. There are just too many variables in ceiling heights, how far apart the light fittings are spaced and the reflector design. Lighting designers have software and can work out how many lux you will be getting at what height (bench/floor/etc), but unless you are going for task specific lighting you electrician should be able to tell you how many lights you need in each area just working off their experience. What I would consider a standard LED downlight for housing applications would be 45' angle, warm white and about 9W.

Many might like neutral light - not yellow - but I agree in basic terms. You might have to just go for it and change globes if necessary in some areas after the event. An interesting topic alright.
