Browse Forums Lighting + Lighting Design 1 Aug 20, 2013 11:43 am Hi all, I am clueless about lights. I was wondering if these lights from beacon http://www.beaconlighting.com.au/energy-saving/downlights-bulbs-globes/ledlux-11w-downlight-kit-in-brushed-chrome-with-warm-white-globes.html would be adequate for general lighting throughout my house, ceiling 2400? If so, what kind of spacing would you need? How would I work out how many I would need. These are ~$60 per light is it worth spending the extra money on a better light or would it be more cost effective to get something like this http://www.beaconlighting.com.au/energy-saving/downlights-bulbs-globes/ledlux-9w-brushed-chrome-cree-led-downlight-kit-in-warm-white.html and have more of them?

They have better light diffusion and stuff whereas the cheaper ones only kind of light a lesser radius. So you would need less of the expensive ones then the cheap ones right? They are 11W 600 Lumen ones with 150 degree radius. The cheap ones are 9W 400 Lumen 70 degree radius. That seems like a big difference but I don't really know. The space I need the most help lighting is the open plan living, kitchen, dining area which is about 30m2 in area. I want to be able to effectively light the space with downlights and use pendants only as features/ occasional lighting.

There are numerous here, with many varied views, along with recommendation of various light brands. Compared to what I bought that price is dearer and 4 light an area 8m x 7m with a claimed 1400 (others state it is less but still more than others on the market). I cannot be bothered mentioning the brand due to the crap that normally starts with it. Search the threads and you will gain much information.

You have 4 downlights in an 8x7 room? How much did you pay for your downlights? I tried looking on the other threads but most of it gets pretty technical and I thought I understood it basically which is why I posted just to clarify. Obviously I don't understand though. You can probably find an 11W, 600 lumen, 150 degree downlight cheaper at a different store/ website, I'm sure. All I really wanted is a comparison between the cheaper and more expensive on the same website so that I can figure out what is worth paying more for and what specifications make a difference. I'm probably not actually getting them from beacon, it was just an example of two downlights at different price ranges and with different specs.

"Incandescent & halogen downlights??" and go to page 1. Photos will indicate what the LED lights we have are like. We run them dimmed 95% of the time. They are a 90mm light. a DL-9. The 70mm is a DL-7. To check prices simply go to their online store, or search on the forum for wattsaver. There have been quite a number of people on here now that have purchased them. As for "claimed 1400", a "lighting expert" disputed this figure although admitted they were the brightest on the market. I do not believe Brightgreen LED's are as bright, and nearly twice the price.

These are rated at 1400 lumen. A normal 50 watt halogen is rated about the 700 lumen, so these are about twice as bright.

I want to be able to effectively light the space with downlights and use pendants only as features/ occasional lighting. Our open plan living, dining, kitchen is 11.3m long by 5.8m wide (raked ceiling also) We have 6 (2 rows of 3) 11W downlights over the living area, 6 (2 rows of 3) 11W downlights over the dining area a single row of 3 11W downlights over the kitchen, but the kitchen also has 3 pendent lights over the island and LED strip lighting under the overhead cabinets. All on, probably a bit more light than you really need BUT the trick to all this is to put them all on dimmers (as delatite13 mentioned) - total control over the look you want. The other thing to worry about is what colour to use where? (Daylight, warm-white, cool-white, etc) Best thing you can do is go into Beacon (or any other lighting shop) and have them explain (using lights in the shop) what it all means. Good luck! ----------------------------------------------- http://pab34newdigs.blogspot.com.au/ ----------------------------------------------- Re: LED for general lighting and estimate on spacing? 9Aug 23, 2013 10:27 am Thanks everyone I think I have a pretty good idea now.

Yep - The entire house has LED's (about 110-120 total + 9 strips of LED strip lighting) Bedrooms all have 4 DL's Bathrooms have a central 4in1 unit with at least 1 LED DL over every shower head and bath and 1 LED DL over each vanity basin. ----------------------------------------------- http://pab34newdigs.blogspot.com.au/ ----------------------------------------------- Re: LED for general lighting and estimate on spacing? 13Oct 30, 2013 12:34 am I realise this thread has been inactive for a while, but I just came across it and wanted to add, for anyone looking at spacing of LED downlights... Brightgreen website & app allow you to enter your room dimensions and ceiling heights & it will tell you how many downlights it recommends. This is a very useful tool for people without experience in lighting design. My entire house is going to be LED, including external lights, feature lights, rangehood lighting. The different LED brands vary in their effect in a room so designing with them can be difficult. Re: LED for general lighting and estimate on spacing? 14Jan 08, 2014 6:31 pm Hi Guys, Some great advice here. Generally speaking, LED's vary in so many ways, and it comes down to lumens per watt. If you can find a high quality LED downlight which produces high Lumen out put and at a good beam angle, I would suggest in going for something like this. Because after all, you will be paying the electrical bill, and the more watts used, they higher the bill. especially if you have 120 downlights in the house.

But don't you think that LED is not good for rooms as it has very sharp light? Buy Lighting Online In Australia @ Wholesale Prices. Re: LED for general lighting and estimate on spacing? 16Mar 01, 2015 7:31 am One major thing you need to consider is glare. Any LED downlights punch out a lot of lumens through a very small opening. If you have an LED downlight with an extremely wide beam like 80 degrees or more, this means that the LED chips need to be very close to the face of the downlight, and normally covered with some sort of an opaque diffuser. These have uncontrolled light output and are generally the cheaper style. What happens is this creates extremely bright and glarey spots on your ceiling. This is what we call "visual discomfort". It's not good for your eyes, but it also makes the room seem smaller because the perception of the room is limited due to the glare. A far better way to light rooms and lounge areas is to use low-glare light sources and try to illuminate the walls. You can do this in several ways, one of which is to use tilt adjustable low-glare downlights shining onto the walls. The light will bounce around the room as it is reflected by the floor and ceiling. Light coloured finishes reflect light much better than dark ones. Low glare downlights usually have the LED chips set back a long way into the luminaire so that when the lights are on and you're moving about the room, you don't really notice any bright glarey spots on the ceiling. Personally, I wouldn't buy lights from beacon. I think they are over priced for what they are (rebadged made in China low quality). For the prices they charge you could buy decent brand lights from an electrical wholesaler (well known lighting manufacturers like Philips, Sylvania, Pierlite etc).

Thanks 1960s, you just made me pull out the last few strands of hair that I had lol. I have looked at the diffused down lights and actually thought they were better? Or is it they just "look" better. God damn.. I think a normal light and simple globe might be easier haha.

Re: LED for general lighting and estimate on spacing? 19Mar 01, 2015 9:36 am It depends on the room. I have some of the cheaper wide beam diffused downlights in my hallway, 1) because they're rarely on, 2) because we have cupboards in the hallway and the diffused downlights do a good job of throwing light around indiscriminately into the cupboards. They might be ok in bedrooms, utility areas etc. But personally I wouldn't. But I wouldn't have them in my living areas. Also consider other forms of lighting, wall lights, curtain pelmets and ceiling coffers with LED strip lighting, LED strip lighting concealed under/over kitchen cabinetry etc. In other words - other ways of indirect lighting to create even ambient glow.
