I was put off CFL's, however, when I visited the lighting shop & they illuminated one in their 'downlight room'. The light given off was less bright than the LED, which in itself, is much less than the halogens I am already used to. Re: LED Lighting 22Jan 12, 2009 8:43 pm Hammerhead I had a suggestion put to me: just have 1 lite put into all desingnated LED/CFL area's, pass final inspection, have sparky return to install remainder of lights in same areas with halogens......(ooooo, I did say that????) If the "final inspection" you're talking about is for BASIX, then obviously that would be deceptive, and defeat the purpose of the requirements. I recently inspected a new house where the owner presented me with the BASIX certificate which stated CFL and LED lights had been installed throughout, and I roughly counted there to be about 150 HALOGEN globes installed, and only 2 or 3 LED globes (which were a completely different light fitting anyway), with the date on the form not even 2 weeks prior to my visit. Not that I inspect for BASIX compliance, but if the electrician is ******* enough to do this, what other documentation is going to be not even worth the paper it's written (or printed) on? Incidentally, the electrician was unlicenced for some time, and the quality of work and number of defects (and the dangerous nature of them) was the worst I have seen in several years - this electrician doesn't deserve a licence! I think the worst thing was that it was a project home (and no, I wont mention any names!) Another one for OFT... As for your CFL demonstration in the lighting shop, did you leave the CFL globe on for a couple of minutes then come back to have another look - they take a little while to get up to full brightness and everyone I talk to about them didn't know that fact. Re: LED Lighting 23Jan 18, 2009 2:41 pm LED TUBES - that can be retro fitted into fluro housings - or used as a new ligthing method.
http://www.spectrumlighting.com.au/led_tube_lights.php They also have a great range of downlight fittings as well as data stating LED fluro's are about 90% output of fluros and given that fluros reduce their output as time goes by - LED's will not do this as much - a good choice IMO. Steve Re: LED Lighting 25Jan 26, 2009 1:28 pm abhik I am using LED lights in my home from last 8 months. They are really nice looking. Are you able to post up any photos of how they look when turned on? Re: LED Lighting 27Jan 28, 2009 6:44 am amk - I checked out the cost of LED up/down lights for the outside of our house - $290 each After 4 years - we're in! Re: LED Lighting 28Feb 10, 2009 1:24 pm Along the same lines but a different application. Hella have/are developing LED headlights for cars http://www.hella.co.nz/default.asp?a=55 ... y&newsID=6 . Re: LED Lighting 29Feb 10, 2009 2:14 pm stonecutter1309 amk - I checked out the cost of LED up/down lights for the outside of our house - $290 each $290?! I assume that's globe and fitting? Not sure if I've mentioned it elsewhere on these forums, but 2 or 3 years ago I installed a few LED downlight globes which are rated at 12v, and contain about 20 LEDs in them (I know LED downlight globes have come a long way since then) for above kitchen benches and sink, and while they produce a very narrow "spot" beam, they are still quite effective and useful, and also use negligible power. Of course you'd never get the same output as a 50W halogen globe with the globes I installed, but that wasn't the purpose. The reason I mention it is that for your situation (outdoor lighting) I would expect using a commonly-available weather-proof stainless-steel up/down-light fittings, fitted with these types of globes (were $20 each back then) would provide nice ambient lighting for outside the house. The only catch coul be that you might need double the amount of fittings to get the preferred lighting levels, but it would probably still cost alot less than $290!!! I believe the globes were purchased from a "solar" shop (supplies for self-sustainable energy) in Sydney. I can find out the details of the shop if you like. Re: LED Lighting 30Feb 12, 2009 1:45 pm love LED lighting. was in the entertainment industry just as they where beconming a main stay for wash lighting and replacing alot or MR16 lights. now it is good to see them coming off the stage and into the home...

I run 8x6w outdoor brick lights in a retaining wall. they are fine for ambient light but not to see what your eating. I have them on a light sensor so they are on all night. looks great at night. I have also installed the MR16 LED globes in uplights mounted in my driveway. A couple of things to mention here: The light output or lumens is generally lower compared to traditional halogens. The transformer required (last time i checked) is an Iron Core style. residential electronic transformers require a resistive load to operate. Commercial lighting systems can handle capacitive, inductive or resistive loads. Cable size: you can run multiple lights of a smaller diameter cable than traditional lights too. e.g: garden lights once needed 2.5 or 4mm cable per light dependent on distance. LED can run all the lights on 1,5mm any distance (within reason here folks) Here's 20w leds in action Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Re: LED Lighting 33Feb 13, 2009 7:11 pm At the moment, they need to be larger and with heatsinks to match the lumen output of halogens. Then bring in the price and its a little early to jump onboard.
Sylvania lamps do have a MR16 globe with LED's but it runs closer to the equivalent of 20W, and its lifespan doesn't justify the extra cost. Licenced Sparky and Data Cabler If "The Data Guys" is too long to type, TDG will do. Re: LED Lighting 34Feb 16, 2009 8:22 am The Data Guys
Can you steer me in the right direction in regards to a quality transformer to use when using LED lights in a outdoor environment.( Iron core?)Have not heard of this before. I am wanting to use LEDs uplighting plants in the yard and general purpose lighting as you have done. All up around 20 lights run on the same circuit if possible and would love to use a photocell switch or a sundusk switch (is that the correct term?) I am building in Canberra this year, do you know of any decent sparkies that could do a new house also. Interested..... only kidding . Thanks Cheers Michael He wants a dream home theatre - she wants a dream kitchen! Re: LED Lighting 35Feb 18, 2009 8:25 am An iron core transformer is the original style transformer.
Its basically two wires wrapped around an iron core. one wire is connected to 240V and the output voltage is the other wire. The output voltage is dependent of the wire turn ratio. I use a Nelson brand outdoor transformer. Its 450VA. It is quite expensive and overkill for LED's unless you have 70x 6w lights. This is where you need to be careful. The lights power consumption is expressed in watts (W). Watts are calculated by the voltage (V) and the amperes (A) consumed by the light. Power (watts)= Volts x Amperes. A transformer is rated in VA but it is not a direct comparison to watts. The transformer will consume about 10% more than the load. I found my 450VA transformer was running very hot at 400w (8x 50w globes) so I changed to 20w globes, and now 6w LED's to run cooler. I also have 8 6w led's running of a single 60VA Atco downlight transformer in the roof space, and that works perfect. The lights are around the garden wall and are all run in the same heavy duty garden light cable available at Bunnings. Electronic transformers have been all the rage for a few years now as they don't run as hot and last longer. They only last longer because the iron core transformers would pushed to their limit with 50W globes. The iron core transformers would last 3-5 years. Electronic transformers need a resistive load to work. LED's don't work on them as they are different kind of load. (getting into electrical engineering principles here. Way to deep for me to explain) As with most lights in the garden, voltage drop comes into play. The longer the cable run, the more resistive the cable so the light at the end of the cable will be less bright than the first. LED's may just not work as they need a certain voltage to operate. You can use a large expensive iron core transformer and a larger cable size to do the whole garden on one circuit or use smaller cable and smaller transformers and a few circuits. As for the photocell, HPM do a quality unit that is value for money. It needs to be installed away from direct sunlight or it will die in 3 months. They are around 75mm square and 50mm deep. I didn't want to mount that at my place so I bought a Mactec photocell and pulled it to bits, then mounted just the cell and hid the control gear. http://i727.photobucket.com/albums/ww280/aussieIDI-07/DSC02408.jpg I don't know any decent sparkies. not even me. word of mouth is the only way to find someone. I don't advertise my company at all. I have a website but all my leads come from existing customers references. Its easy for me to do a better job at my place because I'm not paying for labour. I still do my best on all jobs within budget and don't walk off a job until I feel its been done without compromise.

PRISMA LED 36Mar 02, 2009 10:23 pm Not sure if this mob has been mentioned yet, but I thought I'd pass on the details in case anyone might be interested. I've driven past this shop hundreds of times but only noticed it today. It is at Arncliffe, on the end of Forest Rd near Princes Hwy. It has a couple of displays in the windows with alot of colour-changing LED lights. The brand of LED lights is PRISMALED - http://www.prismaled.com.au - I think I found the $180 18W 5xLED fittings (which I saw in a shop in the city last year) on their website. Prices are shown on the website (which I think is great as it allows anyone to work out the total price themselves and gives you an idea of how much you might need to spend). And for absolute over-the-top, check out the LED street/flood lights - at around $2500 each!!! Their website indicates they are interstate, so I guess the shop I drive past must just be a distributor/stockist of their products. Re: 37May 03, 2009 10:45 pm Hey Michael For LED transformers I suggest you considered this brand. MEANWELL www.meanwell.com , they are specialised in LED transfomers and have decent quality and reasonable price. They have a local distributor in Melbourne and Perth. The Melbourne one is called ADM System Pty Ltd www.admtech.com.au I am LED lightng manufacturer which only use Meanwell for my LED lighting fixtures By the way their power supply have C-tick sticker as well James paddy The Data Guys Can you steer me in the right direction in regards to a quality transformer to use when using LED lights in a outdoor environment.( Iron core?)Have not heard of this before.

Thanks Cheers Michael Re: LED Lighting 38May 25, 2009 4:26 pm Hi Guys , have a look at this web site www.hafele.com.au once there go to the Online catalogues and look for the reflections lighting catalogue ,this can be downloaded and is only about 2 megs. Keep you eyes open as I was showed a new 9 watt Led ceiling light that is 95 % as bright as a 50 watt halogen .There is a Led driver and this can run one or two lights . It is only 18 watt driver . Remember most of the high power led`s are run on 700 m/a and these will not work with old halogen transformers as they will blow the led`s immediatley. This light is a complete ceiling fitting .There are two types one with a gimble for commercial and a fixed version ( 5 * Star rated for new homes ) Enjoy and hooray for LED lights . Contact Hafele if you need any other info.
