cheapest I could find LED lights store Negotiated for 6 dimmable GU10 (with connectors to change from the MR16s 50W halogens there now)of them for $235 I'll see how they go before lashing out for another 9 that will cover all the downlights in the house. 3x3W CREE LEDs, same thing at Beacon lighting is $75 each min 2. ($100 for the first and 50% off second) Any thoughts on these energy meters efergy loggable via USB several brands on the market, looks like the most reasonable at under $100 AUD delivered Luck favours the well prepared |

Hi Karl Led lights look good, I am using some but found them to be a bit down on light output, savings on power is great though, I run a 12 volt system separate to power so no blackouts. One benefit is the heat reduction in the room it is noticeable. Also using 1 led across the power in each room to act as a night light so no staggering in the dark to find the light switch. The power meter is OK but doubt the logging facility will be useful once the new toy status wears off, I have a non recording one three phase that is handy for checking various appliances, found a faulty fridge that is using 600 watts so that needs replacement. It logs power usage but not to a computer, interesting but not very useful it cost $50 including installation through local gov. It reads the power back into the grid as a reduction in total usage but not as a separate entity. Solar HWS showed as a reduction of 10 kw per day on the average so that's the best thing I put on so far. Still no wind here to gauge the wind turbine input. All the best Bob Foolin Around |

Geez Bob. I was given a Bey Lea solar hot water system complete (including the two 8'x4' panels and all the plumbing and fixtures)... in mickey mouse condition, and it has sat in the shed for months...... but your power reduction figures have given me new impetus to get it up 
Yes... a slack puppy indeed

Hi Oz Go for it mate its a lot easier to save the kws than to generate it it amazed me that the old HWS was using a lot of power 4 hours a day at 2.5 kw and that was on the full rate no off peak. and the part that annoyed me was that even when I didnt use it it would still heat for 6 min in an hour in the summer and more in the winter. I waited nearly 12 months for them to install the new one and it was worth the wait, with subsidies it cost $1500 installed 400 ltr with all the bells and whistles, since it is on I havnt turned on the power apart from the initial heat up, and that is with lots of overcast weather. Its a split system so no huge load on the roof and the little pump only uses 18 watts so I can live with that. Allthe best Bob Foolin Around |

Hey Karl.. hows the lights going ? Ive tried quite a few different types / styles of MR16 replacement LED lights over the years and have been very disappointed in them.. ive resorted to using 20w halogens for the moment until the technology finally improves.. how do the ones you've got compare to halogens ? did you get spread or spot ? Cheers Steve |

Going great. Its like a load being taken off my mind, they work with the dimmers so all six that I replaced are maxed out at 54W the lot and probably 25W when dimmed. I used to despise even turning them on but now, run them lots! they dont crack out quite as much as the halogens but close enough, i'd say 20% down on output over the halogens. $$/lumen these arent as bad as they look and with the prices Jaycar charger for their LED drivers these look cheap. Kick Ass LED downlight Mine were about $30 each but can get them a little less if you dont want dimmable. certainly beats the crap out of $35 each for 3W LED's at bunnings which would be woeful in light output vs the 3x3W crees. The "ultimate" 7x 3W crees at 900lumens and $70 each (with power supply) would be awesome but tough to justify. Oh they were 60 degree jobs, next ones will be 38 degrees, 60 is too much and wastes light Luck favours the well prepared |

Karl, Here in the states we find the led's dont put out as much light. and the life span is not too good for the price they charge. What we are using mostly is the cork screw florescent bulbs. I have been using some of the cheaper brands and they seem to be holding up good. When the led flash lites first came on the seen in this country I preformed an experiment. I took an egg and my mini mag light with 2 double aa battery's and shined it through the egg like you do when you candle an egg, the mini penetrated the egg then I took my new Brinkman led light also 2 aa battery and it did not penetrate the egg! In an emergency Im glad to have either and use a led to make the night time trip to the toilet.

I recently installed some LED downlights in my kitchen and can't say I regret the decision. I know there are some negative words being spoken about LED lights but I think as long as you get some good quality ones you won't have any problems. http://www.ecoledlight.co.uk/led-downlights.asp |

Hi all LED installers Nice to hear some positives about LED's. For my liking the light is usefull but not agreeable. I installed mostly T5 flouros some years ago already and for me it would be difficult to justify anything else regarding power consumption. But I am looking forward to hear some realy positive (price and performance) improvements and may change my mind. The first light I would use LED is on the toilett. Lot's off ON/OFF's and not much light needed. Ideal for LED's. |
