  • Good buttons for a low price

    posted by Bullback

    For 20 pieces they are really cheap, and I have till now still a lot of fun with them.
    The spec says that they are 1,4mm x 1,4mm this are the upper ring dimensions, NOT the actual hole to fit nice and tight!
    At this moment I don't use them a lot, so I don't know how long these buttons last.But they are nice little buttons for not so much money.

  • Very good. worth its price

    posted by emzi01

    Packaged in 2 plastic bags, might be useful to prevent damage during transportation.Build quality is good, as usual for these devices.Color temperature is warm, but not too yellowish, to me its more than 3000K.
    Used sku.54004 to power it up and PC CPU heat sink to keep it cool.Regular aluminum CPU sink is not enough for long-term usage (may need active cooling).Radiator gets very hot (>50C) after ~30s.
    Compared to other similar devices this one definitely worth buying - price/quality is outstanding.If only it lasts the same time as it should.
  • 20 Watt white ledchip of good quality.

    posted by lasermanathome

    This type of chips is own by me in several wattages, This one, the 20 Watt version is less critical in its cooling demands as the 30, 50 and 100 Watt but still, it needs GOOD COOLING!!When that is in order, the hughe amount of pure white light -like sunlight- is produced without problems for a long, very long time.Even some more than 20 watt is no problem, just keep the chip nice cool
    These leds must be shielded , so you can"t look right into them, the 20 emmiters are long time in your vision when you look in the working led, it is awful bright.
    Best buy, ther 20 Watt version can be cooled more easy than the 50 Watt version.They are ideal fur using them in the kitchen or places where is worked with colors.You can build them in uplighters or armatures wich diffuse the light, they are to bright to look in to sodo not use the bare emitter where it ban be seen directly.Because it's lifespan you can build it in completely.When good cooled and with about 15 Watt, you propable never have to replace it!!
