    uses 3 x 18650 batteries

    I became curious about the LED spotlight "globe" and had a look on aliexpress.

    ended up buying a bare 50W cold white 220v LED for US $2.19 delivered which can be wired to mains. and placed in an appropriate enclosure

    •  

      What kind of enclosure are you going to use?

      •  

        have not totally worked that out yet.

        thinking of mounting the LED on an old cpu heat sink i have in the shed similar to this one.

        maybe utilise an old car headlight for the reflective plate.

        surround the headlightreflective plate with appropriately sized PVC pipping (15cm diameter)

        cut some perspex for front glass/ or just a very fine wire mesh to prevent anyone or anything touching the led.

        handle on top.

        some feet on the bottom for stability.

        I have the mock up in my head.

          That looks like it'll break if you knock it over. :)

          @eug: hence fitting it in appropriately sized PVC pipe

        • +1 vote

          @altomic: Careful with using PVC, even with a heat sink you'll likely end up heating the PVC up and softening it so that it could sag onto a really hot bit. That's when the problems start.
          Grab a thin sheet of steel from somewhere (old sign, chopped up old fridge/washing machine) and fold that into something suitable. Just remember to earth it, but you'd be doing that if you have an exposed heat sink anyway.

        •  

          @banana365: i'd be drilling multiple holes in the pvc pipe for ventilation as well. but certainly, propensity for melting the PVC is worth monitoring. cheers

      Yuck integrated chip. Do not expect much from this chip.

      uses 3 x 18650 batteries

      Hmm, at 20W I wonder what the runtime on high is. The 6 hours quoted has gotta be on a pretty low setting.

      I assume the 3x 18650 will be in parallel. 20W at 3.7V would be 5.4A. Assuming they use 2500mAh cells that'd be 7.5Ah, so 1.38 hours without considering any regulator losses?

    •  

      They flicker rather badly

    •  

      Big clive did a teardown of those LEDs with integrated driving circuitry. What's worrying is that the 20W version already runs very hot, so the 50W version will run even hotter:

      https://www.youtube.com/watch?v=KKd2L9Exw0M

      The electronics will probably survive for a while, but LEDs usually have worse lifespan the hotter they're run at. Make sure to use a good heatsink…

    •  

      Let's be generous and see each of these batteries can supply 10Wh before being recharged, then the light would run for an hour and a half, rather than the claimed 6 hours.
      So we can see that the ad specs are wrong, either for running time or power, but most likely for both.

      So many tips for altomic's DIY led light. I guess it's true, many hands make light work.

    20 Watt bright White LED

    Cool or Warm?

    • +12 votes

      depends what you wear while holding the light.

      rayban sunnies = cool
      parker + beanie = warm

  •  

    It's a very good cool Bright LED . Bought the same one from Masters ( what is that ? ) and its been happy with the quality .

  •  

    Does this model have dimmable controls? I bought one off Repco a few years back that allowed the brightness to be adjusted. Thinking of buying another one. Thanks.

    Thanks OP, don't need it but bought one anyway.

    You could try and price match at bunnings https://www.bunnings.com.au/nu-tec-20w-rechargeable-led-work... doubt you could get 10% off of the discounted eBay price, but you should be able to for the sale price.

    I have been using this one for around 18+ months 'til now including a few trips to the sea, it's still going strong. Good solid built, cool white light, easily 6+ hours on 1 charge. The only issue is that there's no charging indication LED (can't tell if it's charging / fully charged).

    • +2 votes

      got mine over a year ago as well. agree with the indicator, but in terms of charging doesn't your have a led on the charger?

      red is still charging, yellow (more like a green and red led on) is almost charged. green fully charged

      love it nice any bright, also carry 3 spare battery if i know im going out long.

      otherwise run direct power from a cig plug to the boat.

        Oh. I've just had a close look at the original charger, it does have an indicator LED there. Thanks for pointing that out :)

      easily 6+ hours on 1 charge

      Are there brightness settings? If it's 6 hours at full brightness, it can't be 20W.

    4 18650s in there.

    Just sent them a message as, as expected, the specs were wrong.

    Hi,

    I received the lights today, however they're not as it says in the ad. You're advertising them as 20W lights that run for up to 6 hours.
    On the sticker on the back, it says that they're 8800mAh batteries at 3.7V. This gives a total stored energy of 32.56Wh. Dividing this by 20W gives us a running time of 1.628 hours, or just a quarter over the claimed time.
    So either, the light isn't going to run for six hours, the LEDs aren't 20W or most likely both.

    Regards,

  •  

    Got mine today also. Sort of agree with spludgey comments but have had mine running strong for the last 4+ hours. Will see if they get to the claimed 6+ hours. l don't believe they are 20w but they do give of sufficient lighting for my camping needs without looking like National Lampoons Christmas. Certainly not worth the $65 but at $36 it is still pretty good value. Back in stock on Ebay for $36 for anyone interested. http://www.ebay.com.au/itm/Portable-Worklight-LED-20-Watt-Re...

    Received mine today. Fully charged it, then opened it up and took some measurements. The battery pack is set of four 3.7V 2,200mAh cells wired in a 2S2P arrangement. Everything is hot-glued in place.

    Power draw was only 6.14 watts - far from the claimed 20 watts.

    There is no regulation or protection circuitry visible, just a current-limiting resistor. You can damage the battery by leaving the light running till it's flat. The charging circuitry is in the mains adaptor so it's very important not to use any regular power supply to charge it.

    Internal photo here.

    At 6.14W, the theoretical max runtime from the 32.56Wh battery pack is 5.3 hours. In reality it'll go for a bit longer, it'll just get dimmer and dimmer to the point of being unusable.

  •  

    You can damage the battery by leaving the light running till it's flat.

    In the manual it states to discharge the battery completely for the first 3 uses?

    •  

      Mmm, either the cells have internal protection, or they copy/pasted that from another light. :)

  •  

    It came in handy after power went down in last night's storm - I had it running for a couple of hours.

    Apparently power hasn't been restored, so will get another workout tonight.
