  Hi OP,

  A couple of questions for you please:

  (1) Building a new home, what type of LED Downlights would you recommend? Preferably between 12-15W so the spacing can be higher, Cool White, gimble and dimmable. Would you recommend SMD and COB ?
  (2) Why is this Revo range so much cheaper than the rest? Is Polyamide body better than Aluminium for heat dissipation? Would this be suitable for a new home? Understand it is slightly lower lumens and non-gimble.

  Thanks,

    I bought a few of these last year (http://premiumlighting.com.au/product/ruby-downlight-series/)

    I plugged it in and after 4 hours of having it on they were so cool (not as cool as a cucumber)

    There were 8 of us friends who bought them in bulk so we got them for $20 each with the chrome finish and the 10 watt ones. I used to have 8 hallogens in my kitchen with a total over 100 watts and just 5 of these Leds are so much brighter.

    COB will give much less glare than SMD. Some good explanations on Whirlpool here, here and here. Also COB will give more consistent colour during its lifetime.

      COB will give much less glare than SMD

      A COB downlight with a baffle will give less glare than these white diffusers with SMDs behind them.

      COB is far more difficult to control the glare with. Larger source needs larger optics to provide same level of glare performance and beam control.

      These downlights that have a white plastic disk (ie: zero optics whatsoever) are pretty much the most glare-producing "downlight" available.

      Also COB will give more consistent colour during its lifetime.

      Almost certainly not. COB gets hotter, and heat is what causes the colour shift in the LEDs.

      The colour shifts of individual chips inside a COB might not be as noticeable as the colour difference between (say) 5 or 8 x SMD, however nobody will ever notice it as nobody (can or will) look up and compare.

      In any even half-decent LED chips, colour change during life is not really much of a concern. This certainly affected old 5mm indicator LEDs and many of the cheap garden lights, as the LED packages have no way of keeping themselves cool so they change colour and fade away extremely quickly. If you are seeing colour shift from any modern interior lighting product, then the luminaire has some serious heat issues and colour is the least of your problems.

    no clear winners for SMD vs COB, depends on application. COB downlights usually are recessed to give beam angle of 60, hence lower glare. A low quality no brand COB will definitely be worse than a branded SMD chip.

    Revo is cheap since its not Al. Nothing beat a solid piece of Al for heat dissipation. Also driver sits on top of the light, making them smoking hot. The Capacitors in the drivers will go before anything else. Stability is also poor since it's impossible to integrate some components into a tiny space. Spend $20 and buy a quality one with a separate driver.

    I wouldn't go over 10W (from a quality brand) for standard 2.4m ceiling, else it will be too much glare. Also get dimmers for bedrooms and living rooms.

    Hi Batrarobin,

    Congrats on the house! To answer your questions:

    (1) Just to clarify, SMD have multiple chips on the circuit board, such as our rondo and flat downlights, as well as these ones on the deal, the Revos. COB - are single chip, (chip on board), and are found in our MDL range.
    Choosing which one is better for you really comes own to personal preference - you can take into account the features of the house, woodgrain, design, ceiling heights, colour of the wall, its really where personal preference and design comes in.

    (2) The Revos are our flagship product, and so buying in bulk allows us to sell them at much cheaper then everybody else. Aluminium is better then Polyamide, but Polyamide is where the industries headed as its cheaper then aluminium as a heat sink. Saying that, Telbix has sold over half a million Revos, they are a fantastic little unit, as well as being Australian certified.

    In response to an earlier comment, the Revos don't get "smoking hot" - there are downlights out there they get to 85-90 degrees, which is at the very edge of what is acceptable in terms of heat. Like all of our lights, we have had the Revos independently tested by a lab and it puts out heat at 43 degrees.

    Hope this helps, good luck with the house!

      Interested to see how you get 43 degrees considering these SAL ones run at 75 degrees in 26 degrees weather.

      (2) The Revos are our flagship product,

      Geeze - you sure set the bar pretty low. I shudder to think how bad your low-end models are! ROFL

      I just checked the website, and the REVO is your lowest grade, cheapest downlight product. Your flagship is the "Tornado" at $109.24 each, and in domestic your flagship would be the MDL403.

      Like all of our lights, we have had the Revos independently tested by a lab and it puts out heat at 43 degrees.

      The test report on your website shows that the maximum temperature under normal voltages (T4) when tested to AS/NZS 60598.2.1 "New Zealand Only" tests for IC (covered in insulation) is 62.3°C in a 25°C ambient.

      Which just goes to show why the plastic material is chosen - it's a far better heat insulator than aluminium. So, the outside of the downlight stays cooler, but the LEDs run hot as they have no way of conducting heat away.

    (1) Building a new home, what type of LED Downlights would you recommend?

    The ones that best suit your requirements. Contact a lighting specialist and get some impartial advice.

    Preferably between 12-15W so the spacing can be higher,

    That is a really really bad decision. Are you proposing to use downlights as your main lighting for everything? If so, why?

    You realise that downlights are for lighting the floor, or angled at artwork etc… not for illuminating spaces? Do you realise that the farther apart they are, the worse the shadowing and vertical illumination (for example on peoples faces) will be?

    Cool White, gimble and dimmable

    Why cool white - want it to look like a supermarket?

    Gimbal is useless unless the product has have a beam angle that is defined enough to be worth "aiming".

    How dimmable do you need them to be, and how do you propose to dim them?

    Why is this Revo range so much cheaper than the rest?

    It's the absolute lowest form of LED downlight possible to make. The cheapest and nastiest. The opposite of "the best".

    Is Polyamide body better than Aluminium for heat dissipation?

    No, it's cheaper for the manufacturer.

    Understand it is slightly lower lumens

    Compared to what? Lumens is irrelevant, it's performance that matters.

  Sunny ecogem are the best in my opinion. (5 years in lighting industry)
