I've tried some of the other recommended brands but harder to find the narrower beam. I don't wanted spoil it by choosing crappy lights! Obviously we are building new al they don't need to be compatible with halogen cut outs just want that right type of more focussed light. There's also these which is the same brand as elsewhere in a 60degree tilt but is it worth spending the extra on them for the living room, Kitchen and lounge compared to say the starburst which are cheaper..want the light in those areas to be right though. https://www.golights.com.au/led-downlig ... s-lighting Custom knockdown rebuild Newcastle NSW viewtopic.php?t=78271 To be honest, the Pierlite starburst is probably going to be around that price anyway, so maybe just go with the Domus? I didn't even know they did it in a gimble tilt actually... Ok thanks. Have found the pierlite in a 10pk for $490 so it's about $20 per light difference. But need to factor can't buy exact amount with the 10pk http://www.aussietradesupplies.com.au/c ... ts_10_pack Would be nice to have them all the same I guess. I'm pretty sure that link I posted is the right domus anyway. Thanks so much for your help merry Christmas.

Eg up/downs. Husband wants them really bright for some reason, clean, contemporary style etc. merry Christmas!! Custom knockdown rebuild Newcastle NSW viewtopic.php?t=78271 Re: Ask a lighting design engineer - general Q&A 135Dec 23, 2015 7:20 pm When it comes to exterior, because my work is all non-residential the exterior luminaires I'm familiar with are all in the several hundred or even thousands of dollars. However, I had a look on the Domus website and they have some nice looking exterior up/downs. I particularly like the "Block" range - they look quite contemporary and clean, with what appears to be a decent output. From what I can find they seem to retail around the $140-150 mark which seems reasonable. https://www.domuslighting.com.au/exteri ... ue%2319578 Building Services Engineer Renovating our 1960's modernist home in Brisbane https://forum.homeone.com.au/viewtopic.php?f=53&t=82091 Re: Ask a lighting design engineer - general Q&A 136Dec 27, 2015 1:30 pm 1960sModernistHome When it comes to exterior, because my work is all non-residential the exterior luminaires I'm familiar with are all in the several hundred or even thousands of dollars.

Custom knockdown rebuild Newcastle NSW viewtopic.php?t=78271 Re: Ask a lighting design engineer - general Q&A 137Jan 03, 2016 1:10 pm Hi i am currently designing my landscaping lighting plan, can you please take a look at my lighting plan to see if it all makes sense. Also im worried about voltage drop 1.Are my light runs ok,what size cable would you recommend? 1.3mm or 3.3mm? or a combination. 2. would i need to loop back? 3. it is an issue if my LED watt usage is about 35W less than transformer, i have read that this can cause issues? Any advice appreciated. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Re: Ask a lighting design engineer - general Q&A 138Jan 03, 2016 3:43 pm Looks impressive. Can't wait to see it all done. Just a few questions before I respond properly... 1. Are the lights 12 volts AC or DC? Or are they able to work with both AC or DC? 2. Are you sure they are all 12v wired in parallel? (Constant voltage)? Some LED landscape lights need to be wired in series and they are constant current (voltage varies depending on the load and voltage drop). Your lights are all very low power so I wouldn't be too concerned about voltage drop. On face value it doesn't look concerning.

Before i go on, just wanted to say that i wont be doing any of the 240V stuff myself, i know my limits, but i do need to plan it in as i want to pre-purchase all the components. Anyways to answer your questions, i'm pretty sure the lights are all DC but im not sure if any need to be wired in series? I have had to update the plan a i realised one of my lights was not 12V.

Wouldn't hurt to run a ring circuit around just to be on the safe side Re: Ask a lighting design engineer - general Q&A 140Jan 04, 2016 9:12 am Glad you cleared that up about the 240v stuff. I'm happy to give out some advice about 12v stuff because there are no regulations on who can do it as far as I am aware, and also there is no real safety hazard from extra low voltage stuff as it is designed to be inherently safe. Ok so from what I can tell it looks like your lights will function on 12V DC. The 12V power supplies you have chosen will be fine, under-running them should not be an issue. One thing I would suggest though is if you buy a waterproof power supply, don't put it inside an enclosure. The aluminium casing of the power supply is its heat sink so it's best to be left open so that it can keep cool. Otherwise you run the risk of it over heating and failing. With your 12V cabling, you can use a combination of ring circuit, branch circuit and spurs off the circuit. Basically you can run the cables around however best suits your layout. It will help voltage drop if you are able to split the load up into numerous branch circuits and run them back to the power supply. Your end goal is to reduce the cable distance from the furthest light back to the power supply. With 12V LED i'd say if you can keep that distance less than 15-20mtrs you should be right. With a ring circuit, you run your cabling around to all the lights, looping in and out, and then from the last light on the circuit run back to the power supply. This means you feed voltage to the circuit from both ends, roughly halving voltage drop. I had to do this on a previous home where I had 12v 20w halogen lights around our pool - but these days with LED the load is around 80% less then halogen so it's become almost a non-issue to some extent. As for cable type, when I did my landscape lighting here I had an old 305 metre roll of cat5e data cable which I was not going to use for anything else (my house data points are all cat6). So I used that. cat5e has 8 separately insulated cores, so I just twisted 4 + 4 of them together to make it a 2 core cable. Ran everything in rigid PVC conduit in the ground. I got some 12V DC power supplies (they look just like a laptop charger) and all works well. I ran every light back to the power supply on its own cable so that I didn't have any joins in the ground to fail, plus the cat5e cable was free and plentiful... and even if you had to buy cat5e it's much cheaper than 12v garden light cable. The advantage of the garden light cable is that it usually has a thick, tough sheath, but I would ALWAYS install any landscape lighting cabling inside conduit anyway so the sheath is not as important if its in conduit. Make sure all of your cable joins are waterproof, especially if they are near, on or below ground level. You should be able to buy little resin join kits. But just be aware they aren't cheap. You might be able to make your joins inside each light, which is probably the go if you can. Just make sure the cable entry into the light fitting is thoroughly waterproofed afterwards. Your LED controller should work fine with any RGB LED strip. I have used one of these controllers in my ensuite for some RGB LED wall washers http://www.ebay.com.au/itm/TM08U-Touch-Panel-Controller-Dimmer-Wall-Switch-For-RGB-LED-Strip-12-24V-12A-WH-/251681129077?hash=item3a995d4275:g:8x0AAOSwcu5UQIYo and it works well. You can select the colour you want from the colour wheel for statis display, or there are a whole bunch of programs that flash, fade, change colour etc. And you dim up/down with the slider bar. Again I just ran a 2 core wire from the 12V power supply to the controller, and then a cat5e from the controller to the LED strip, and then twisted together 4 of the pairs to make it a 4 core cable. If you really wanted to turn this into an interesting electronics project, you could look at a 12v solar panel, battery charger and a 12V battery. Run it "off grid"... I would like to do that with my landscape lighting at some point in the future.
