3w emitter Customers Reviews

  • So very cold and bright

    posted by llasher

    Cheap
    Cold white light
    A good price for a 3 emitter cold white LED. The strip is a good form factor: attaches easily to an aluminium strip heatsink type deal that you can DIY (I bought some alum L shaped stock from the local hardware chain).
    They call these street lights. I call it street life, like in the song. I had to dremel a bit, I can't understand why the lens screw holes don't align with those on the aluminium base of the LEDs.
  • perfect rgb lightsource

    posted by lasermanathome

    A almost perfect lightsource to make almost every color of light you want.
    Very bright.
    This led can be used for almost every lightapplication.
    The blue chip has the most overkill.
    You can make your light, when you want white, about every colortemperature.
    The red color in not 650 but about
    630 nM.
    No possibility so use the leds in serie if you want to be able to adjust the color.
    With resistors however you can
    program every led differently.
    Therefor it is a little inconvenient to make your own highoutput RGB controllable spotlight.
    Collimation is also difficult, the lightspot is not homogenic in color.
    For this price however.......
    The price and the possibilities are
    great, to reach the expected result is tricky and not easy.
    When you keep trying, you will find the way to make any kind of light you want with this RGB powerled.
  • Good 12v LED warm light bar for projects

    posted by Wudan

    Easy to power with 12v sourceLight has a nice warm colourVery bright for sizeSolder pads (-/+) on each side allowing for variety of wiring configurationsPre-drilled holes in aluminium base for mounting or attaching heat sinks
    I run these through SKU: 168324 to easily control brightness.
    Decent LED light bar for project use.Price still a bit expensive considering other alternatives.
  • Not Bad

    posted by jasonlepak

    The light is very bright and very low cost compared to what you'd find trying to buy something like this in the states.Easy to solder leads or wires to and can be chained together to make a very bright multi strip light.
    None
    I'm definitely going to be buying more like this one in the future.Might even do my whole house with LED's through DX.com
  • Great Micro Led for the light output

    posted by chrisal

    - Extremely powerful LED- Easy to assemble - any one of the thre terminals from each site powers up the three led pads.- Very Small- Good color temperature! Not blueish... Reminds Mercury vapour HID lamps...
    - Generates quite heat, so USE ONLY with heat radiator. I am using a single passive with 4cm x 2cm and it reaches easily >60C degrees.- Use thermal compounds to improve heat transmission to radiator;
    It´s excelent led emitter for those who enjoy assemble your own led lightnings. Need technical skills otherwise will burn this unit.
