    Hi! Sparkyonline here, price is going up by $2 in 30 minutes (11:30am) - we didn't expect this promo to get this big this quick! Is still crazy cheap for fully credited, telbix downlights with 3 year warranty :) Still use sparky123 at checkout for 10% off :)

  • BadGiraffe on 19/04/2016 - 11:29

    So… with these downlights, I take it you can't simply change the bulb if it blows. You have change the entire fixture, right? So would I be able to get something that looks the same from, say Bunnings down the line? Would, say 5 years from now, would I still be able to get something that looks like that so that all my downlights look the same?

    This isn't some industry standard look and feel, right?

    • Timfoo on 19/04/2016 - 11:33

      Yes most kits these days just plug into the plug base and the face looks very similar,
      Most of the time is something dies it the driver and not the led chip they last for long time. If your paranoid buy a few spares ;)

      • BadGiraffe on 19/04/2016 - 12:25

        But what if the spares don't last?

        Paranoia going into overdrive here….

          These LEDs are DISPOSABLE products.

          Would, say 5 years from now, would I still be able to get something that looks like that so that all my downlights look the same?

          Nope. Even if you did find one that matched, the colour of light and the amount of light would never match.

          When one fails, you replace ALL of them in a room.

          The ones that still work become your "spares" for the next room.

          This isn't some industry standard look and feel, right?

          There are squillions of this style at the moment - they are the latest "lowest possible denominator" recessed light that has replaced the GU10 halogen.

          In a few years time there will be something even shittier and cheaper, don't you worry. It's a race to the bottom, and this style of product is the current winner.

        • BadGiraffe on 20/04/2016 - 22:27

          @llama: You, sir, have answered my questions, and then some. I never thought about a replacement lamp not matching the light of the existing ones.

          Well… I guess it's off to IKEA for me then. Things are pretty standard over there. They're like the Apple of home decor.

        • llama on 20/04/2016 - 22:58

          @flaminglemon:

          I guess it's off to IKEA for me then. Things are pretty standard over there. They're like the Apple of home decor.

          LOL WOT?

          A LED lamp you get from Ikea will only be available until that shipment is sold. You won't get a matching Ikea lamp in 6 months time. There is no such thing as a "standard" LED product… it's completely the reverse.

          As LED lamps age, they get dimmer (fade) and theya also shift in colour. This effect was very dramatic in old LED lamps that used 5mm diameter indicator LED Chips, and is still happening even I the latest and greatest ones today. You should expect that the cheapest ones will be poorer performers in this regard.

          Let's say you bought 2 spare lamps and tested to ensure that they were 100% identical at time of installation. If you install one of those brand new lamps to replace a failed one in a room, the new one will not match the remaining ones that have been operated for some time.

          As I said before about LEDs - When one fails, you replace ALL of them in a room.

        • BadGiraffe on 22/04/2016 - 11:36

          @llama: Electrical enginner, I'm guessing? I've got a friend who is, and he does lighting. This all sounds very familiar to me.

          Very well then. I'll get fixtures which allow me to change lamps easily (my current ones don't). Then I'll get some fairly reasonably priced, but reasonable quality lamps when they blow. Even if they're from IKEA, I suppose. Whether I change all of them at once, I guess I'll do that if I see a need to.

          Thanks for the info. It helps talking to people who know their stuff.

        • llama on 22/04/2016 - 13:20

          @flaminglemon:

          I am a LIGHTING engineer. Electrical engineers generally know very little about the technicalities of lighting.

          Very well then. I'll get fixtures which allow me to change lamps easily

          WHY? Those are the worst kind of LEDs, as they contain numerous compromises. There is no standard LED lamps, so the only ones that allow you to change LEDs are the Halogen retrofit lamps.

          Then I'll get some fairly reasonably priced, but reasonable quality lamps when they blow.

          The problem is that the only LED lamps that blow are the retrofit ones. That's because they have the LED Chips and the Driver circuit all in one package. The driver is the thing that most commonly fails, and it fails due to heat. The retrofit lamp forces you to replace the entire thing when the most commonly failing component dies.

          They don't make (proper) LED fixtures what have replaceable lamps because to work properly the LED chips must have a good THERMAL interface to the outside world. That means being screwed in tightly and often glued to a heatsink in the fixture.

          If the LED fixture is designed properly, the LED Chips will pretty much never die. If kept cool enough, LEDs will continually depreciate in light output but this will take many 10's of thousands of hours.

          The driver circuit however is unlikely to last 30,000 hours, and much less if it gets hot. That's why retrofit lamps that are rated at "100,000 hours" only last a few months… they overheat the driver inside them.

          Whether I change all of them at once, I guess I'll do that if I see a need to.

          You are making a choice that is completely wrong, on a premise that is erroneous.

          It helps talking to people who know their stuff.

          It worries me that you have somehow come to a conclusion that is 100% COMPLETELY the opposite to the advice that I was trying to give you.

          What you need is a good quality fixture which creates an environment where the LEDs don't overheat and fade quickly. Second, you need a setup where the driver can be changed easily.

          It is not practical to make a good LED fixture where the lamp can be changed. In fact, it's pretty much impossible, for thermal reasons. The entire idea of LEDs is that you chuck the whole thing away when the LEDs output fades or if they completely die.

          So, you honestly need to get rid of this focus on "replaceable lamps". It is almost completely irrelevant in LEDs, and there are far more important aspects to product choice than that.

        • BadGiraffe on 22/04/2016 - 16:51

          @llama: Yeah okay. I admit I read your posts a little hastily. I was reading it while doing work. Something had to give.

          I have downlights that I want to replace. The current ones are sitting in some pretty large holes in the ceiling. They're… what are they called… gimbal?

          I'd like to have
          - minimal plastering done
          - something cost effective in the long run
          - something that will look good and consistent with the rest of the house.

          So… what's a driver? Are there fixtures that have drivers that are easily replaceable? How do I know what to look for, based on my requirements?

          And I take it, this deal here isn't the deal I'm looking for.

        • llama on 22/04/2016 - 18:44

          @flaminglemon:

          I'd like to have…

          You should seek advice from a few independent lighting stores and bring your knowledge up so you can make an informed decision.

          So… what's a driver?

          The driver is the electronics that provide the correct electrical current to the LED chips. The LED chips themselves are really small and have low output and there are quite a large number of them required to create enough light to be useful.

          These groups of LED Chips are what you might kind-of term as a "lamp" but they aren't ever just a single thing like a incandescent lamp is a single object. What's confusing to most people is that there is no standards for these groups of LEDS.

          Those chips, irrespective of how they are configured, must have a certain electrical characteristic provided to them so they work properly and don't blow up. The critical thing is that the Current (not voltage) must be controlled.

          That is done by the LED Driver. The Driver must be exactly matched to whatever the particular LED array needs, and that means the Current must be "exact" and the voltage will sort itself out providing there is enough of it.

          LED Retrofit lamps all must have have a driver inside them. Lamps that run off 12V halogen transformers still have a LED Driver inside them. The LED lamps get really hot and heat is the quickest killer of electronics.

          And I take it, this deal here isn't the deal I'm looking for.

          The style of downlights in this deal are the cheapest possible way of making an LED luminaire. Not the best way, but the absolute cheapest.

          They have a separate driver so that can be replaced if you can find one of matching characteristics. However the downlights is nothing special - a hollow plastic or cast metal shell with a flat PCB and a bunch of LED Chips that shine onto a white bit of plastic.

          Absolutely no "optics", basically the same as an old oyster light but recessed into the ceiling. The glare will be considerable, but that only matters in some situations.

          So in some situations these might be OK, but in other situations they'd be awful. The fact that the LEDS are permanently mounted is irrelevant - like all dedicated LED fixtures, if the LED array fails then you replace the fixture. Who cares, it's only worth $10.

  • placard on 19/04/2016 - 14:42

    I do worry about this type of light…they are becoming very cheap and used in large volume apartments/houses etc.

    I've seen first hand them not working after 3-6 months…

        At least they just unplug for replacement.

        Still need an electrician to perform the removal and replacement. This is clearly stated in the electrical safety regulations, as the "legality" applies to the whole installation and not just how the electricity gets connected.

        ACL should cover the rest of return cost.

        ROFL, good luck with that.

          @Steptoe:

          I agree.

          These "downlights" are rubbish but they are like plastic shopping bags you get at the supermarket… the cost is so low that it doesn't matter if they get a hole in them.

          I've been in the lighting industry for about 35 years, and I am disgusted by the waste of energy and resources that is part and parcel with LED Lighting.

          We used to have offices illuminated with luminaires where the end user could replace a lamp when it failed. Now we install units that can't be repaired by anybody.

          Commercial Lighting fitouts used to be based on 10 year life cycle but in reality they stayed in for 20 years. LEDs will be lucky to get 1/4 of that life.

  • StevieRay on 19/04/2016 - 15:11

    Just found this site which measures LEDs from various manufacturers.
    Bit of a worry that the (different) telbix tested here flickered quite a fair bit.

    http://www.ledbenchmark.com/display.php?id=351&name=Telbix+1…

    On another note, went to lighting empire and they took the case of the driver off to show the innards.
    Was very interesting to see the difference between a cheap driver and a more expensive one.
    Essentially more capacitors and "stuff"

    • Steptoe on 19/04/2016 - 15:15

      LED Benchmark is a good resource, agreed

      The link is for a different unit, so hardly comparable to the item in this deal.

  • placard on 19/04/2016 - 15:44

    Any reason why these type of lights are not overly efficient?

    For example the Philips standard E27 bulb - 9.5w gives 806 lumens

    This one is 10w and only 650 lumens…

    • Timfoo on 19/04/2016 - 16:45

      Still better than a halogen. apple and oranges Downloght vs battern holder mate.

      • Steptoe on 19/04/2016 - 16:58

        Light temperature/colour and product design effect efficiency.

    • llama on 20/04/2016 - 20:36

      Yes, a very good reason - they are cheap shit.
