It meets my criteria of having low glare properties and reasonably good build and light output quality. Trade price is around the $40-50 mark depending on spec.

Thanks for the great info and thanks in advance for your help. I've just completed a draft of our lighting plan (see below). We were originally going to go for a ~$3200 lighting package with the builder until I came across this thread and realised that the downlights they supply are the LEDLux Vivid from Beacon Lighting with 105 degree beam angle. Now that I've gone through this thread, I'm convinced to go with low glare downlights instead so we are going to be supplying the lights ourselves and the electrician will install. We don't have a big budget, I'd say $5-8K for lighting/electrical. Also, our ceilings are 2.7M high. I haven't decided on a downlight model yet as I don't know which ones are bright enough for our home. As you can see from our plan, I don't have as many downlights as a lot of other plans in this thread, but I'm hoping its enough. My concerns/questions are: 1. BED 1 and Media not sure if its enough light? 2. Only one downlight in bedroom hallway is that okay? 3. Can I get rid of the middle downlight in the entrance hallway? 4. Can I get rid of the top most light in the kitchen? 5. Single downlight to Entry Porch okay? 6. Alfresco lighting sufficient? 7. Ensuite Lighting okay? 8. We'll put a dimmer in Media, wondering if its beneficial to put a dimmer in BED 1 and/or Meals/Family? 9. We're interested in a mirror light for ensuite only, deciding between downlight or above mirror horizontal wall light (dont want pendant), whats better for make-up/shaving purposes? 10. Other feedback? Thanks so much for your help!

As you can see from our plan, I don't have as many downlights as a lot of other plans in this thread, but I'm hoping its enough. My concerns/questions are: 1. BED 1 and Media not sure if its enough light? I'd probably go with four downlights 2. Only one downlight in bedroom hallway is that okay? I'd probably go with two, one of them in front of the linen cupboard so you can see what you're looking for 3. Can I get rid of the middle downlight in the entrance hallway? Yeah probably, that should be ok 4. Can I get rid of the top most light in the kitchen? Yep, ditch it. And shift the two that are left so they are more above the bench, either side of the rangehood. You want the downlights to light up the bench and cupboards, not the floor 5. Single downlight to Entry Porch okay? Yep 6. Alfresco lighting sufficient? Probably, but consider where you might position a BBQ. Need decent light over the BBQ to make sure you don't over-do the steaks! 7. Ensuite Lighting okay? See item 9 8. We'll put a dimmer in Media, wondering if its beneficial to put a dimmer in BED 1 and/or Meals/Family? Totally up to you, Personally though I think if you are on a fixed modest budget you might be better off spending that money on a few extra lights (as per items 1, 2 and 6) 9. We're interested in a mirror light for ensuite only, deciding between downlight or above mirror horizontal wall light (dont want pendant), whats better for make-up/shaving purposes? I think mirror lights or "glowing" pendant lights are best because they throw light directly on your face. Downlights obviously shine down and can create shadows on your face. I'd suggest shifting the two downlights around over the shower and toilet, and installing a wall light above your mirror. 10. Other feedback? Maybe go with a standard oyster light in bed 2, 3 and 4 to claw back some cost savings, then use the extra points left over for some extra downlights as for items 1, 2 and 6. Maybe another light over that little utility area in your garage. Add an extra downlight in the study, and position them so they are directly over the desk location. Thanks so much for your help! Hopefully these few little tweaks help out!

Should I work out the total required lumens for a room first? Then do I need to decide which brand of downlight we'll be using? I'm fine with working out colour and angle but I'm at a bit of a loss as to how many downlights I will need per room if I don't know the wattage and lumens.... Just at a bit of a loss re where to start.... It seems that a lot of the lighting plans here just have downlights on the plans but from initial research I thought you needed to know what type of light (make) and bulb. And, should I be looking at MR16 bulbs? SOrry, this is probably really basic stuff...... Re: Ask a lighting design engineer - general Q&A 227Mar 19, 2016 6:10 pm Hi again, I was having a look at some of the lights Ikea has, and noticed they all seem to be at 2700K. Will it be obvious if I have them in some rooms and 3000K downlights in others or will there not be a visible difference?

I went to look for this bulb at Beacon today and they sales rep says as far as he knows the production of that bulb has stopped about 12 months ago. I've bought 8 light fittings which required that bulbs and I just want to confirm whether his statement is correct or not before I returned them. Thanks in advance for you help.

And, should I be looking at MR16 bulbs? SOrry, this is probably really basic stuff...... Hi As a very loose and general rule of thumb, you could work to something along the lines of around 150 lumens of output, per square metre of floor area that you're wanting to light up. For kitchens, laundry and other areas where you want it nice and bright, I would work more towards 200-300 lumens of output per square metre. If you're using LED luminaires, they typically have a lumen output around 100 lumens per watt. So using the rule of thumb above, if you had a bedroom 3 x 3m = 9m2, or around 1350 lumens. If using LED luminaires that equates to approximately 13-14 watts of lighting in that room. That could be an oyster light in the centre, or multiple small downlights. A bit more wouldn't hurt. I know this thread now has quite a few pages, but if you read through from the start you'll pick up some good tips, as well as having a look at other poster's lighting plans and the feedback I have provided.

Possibly one of the most ridiculous things I've heard in a while. There are millions of light fittings out there with T5 circular tubes, discontinuing manufacture of the tubes would be like discontinuing brake pads to fit Ford Falcons just because they're about to stop making Ford Falcons. Beacon get their lamps from a factory in China I think, perhaps that factory stopped production, but if you go to an electrical wholesaler you'll find them. The globes they sell at Beacon are of questionable quality anyway, try and get something from Osram, Philips, GE or Sylvania. A quick warning though, the tubes probably cost near to what you paid for the entire light fitting... https://www.lampreplacements.com.au/Products/LAMPS/FLUORESCENT/CIRCULAR-TUBE/T5-(2GX13).aspx 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 232Mar 19, 2016 7:56 pm Hello 1960s
So glad I come across this thread, it contains good and valuable info. Quick question, we recently bought one piece of lifX bulb just to test. It is so amazing! As we are currently building, we are now planning to buy this for the majority of lights throughout the house. Have you encountered this bulb before, are they any good in the long term use? Thanks in advance. Re: Ask a lighting design engineer - general Q&A 233Mar 19, 2016 8:02 pm EPaul888 Hello 1960s So glad I come across this thread contains, it really contains good and valuable info.

As we are currently building, we are now planning to buy this for the majority of lights throughout the house. Have you encountered this bulb before, are they any good in the long term use? Thanks in advance. I've never heard of it, but just Googled it and had a look. The idea is kind of cool I guess, but the price seems to be around $100 each, and it also sounds like a really easy way for someone to hack into your Wi-Fi network. I guess it's kind of cool as a gimmick or toy to show your friends, but will it really add value to your life as opposed to flicking the light switch? (rhetorical question) Might be handy in strategic locations, like your front porch light or outside security lights so you can turn them on from your phone when you drive in, or maybe if you're in bed and hear a noise outside you can turn them on. I guess it can have merit. I don't think I'd go to the expense of having them everywhere though.

Majority of our ground floor are led downlights so we may leave them as it is and will just do the first floor rooms with the lifX bulbs. Re: Ask a lighting design engineer - general Q&A 236Mar 20, 2016 10:43 am http://www.trendlighting.com.au/product/XDR10-IP Hi...if you have time can you have a look at the above downlights and let me know what you think about using them for everything-ish.... maybe higher watts/less lights for the hallways. I'll use 3000K and our ceilings are high - 35 course generally in living areas and bedrooms, and raised to 38 courses over enertaining/dining areas, then lowered to 31 courses over kitchen. I'll put tiltable downlights where needed.... I just need a starting point for a good downlight. We are custom building and haven't signed with a builder yet, however, one of our preferred builders said 'Trend' lights.... I'm trying to do this to get an accurate quote and get the PS out of the contract. Not too worried about budget... This downlight is 'medium beam' which I'm just assuming is 60 deg or so.... Also, is there something you've already recommended earlier (the Domus ones, or the Versilux) which is similar? I'm also half thinking of supplying all the lights myself so I know my plan will fit with exactly what downlights go in.... and to buy a bit of time. Any quick answer is fine...I will keep researching!!!

I like the Domus deepset downlight 75 because it's deep set. However, it's only 650 lumens and our ceilings are over 3 metres, so I'm assuming i'll need a lot of them.. Plus, there's no handy distribution graph to help me work out how close together they should be (given ceiling height). Maybe if you tell me what you have in your house I'll just do the same!! I'm getting information overload.......... Re: Ask a lighting design engineer - general Q&A 238Mar 20, 2016 4:10 pm The Trend is a fantastic choice, I would go with that one personally. As for supply, choose the lights you want and get a quote from the builder to supply them, and then see what price you can get them for. Sometimes builders or electricians have good pricing deals set up where they can buy significantly less than a retail customer, which means they can add a reasonable margin and still sell them to you cheaper than you can buy them - a win-win situation.

I've incorporated most of your suggestions into my plan. I've also decided on some downlight models for now, which you've mentioned: I'll use the: Domus 60° 13W 810lm LED Downlight 3000K $53 https://www.golights.com.au/led-downlig ... s-lighting and also to save money, I'll use some 90° angle downlights: Domus 90° 13W 850lm LED Downlight 3000K $26 https://www.golights.com.au/led-downlig ... s-lighting Please see my updated plan: Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Questions 1. I'm using the 90° angle downlights in some points as a way of cost saving, but in case I decide to spend more and get more 60° downlights, are any of these light points actually more suited to the 90° light and left as is? 2. Wondering if any of these Domus deep-set are better choices for any light points as the prices are all similar: https://www.golights.com.au/led-downlig ... s-lighting https://www.golights.com.au/led-downlig ... s-lighting 3. The 3 in 1's in the bathrooms, I realise I don't like the light they produce in the current home I live in (wondering if its just the light bulb brightness/colour?) .. I just did a Google Image search for 'bathroom lighting' and don't see these units in any pictures, are they outdated? Wondering what other options there are and if the exhaust/heat lamps are necessary? 4. Since I've changed the BED 2,3,4 lights to Oysters lights, I'm wondering how easy it is to upgrade later on? I'm thinking maybe replace oysters with ceiling fans and 2-4 downlights per room. And would there be marks left on the ceiling from the Oysters? 5. Back hallway positioning okay? I put one in from of cupboard and other one at T junction. Thanks so much for your help! Much appreciated!!!
