  • great back-lighting solution.

    posted by dustooff

    SMD 5050 standard package layout.each LED has 3 point sources of light,each on a separate pin,this could also be a con.Use as a 3 pixel element.Relatively low height compared to other SMD LED's.
    having 3 LED's in one package could allow for further matrix/multiplexing setup.maybe allows 3 pixels for each LED.Can be 'dead bugged' to make a lighting strip. This eliminates the need to prototype on a PCB.
    will probably buy more of these given stock holds.
  • Very Bright!!! seems like more then 270Lm

    posted by TIPtheTOE

    Very Bright Seems like more then 270 Lumens, Has a very Bright White Light And don't look into the light too long very blinding intense light
    Very Small, Can fit any where A real Good place would be Under the Trunk & inside car & House lighting, will fit just about any where
    Gets kind of Warm,May Require Heat Sink Possible if on for long Operation or On for a long time
  • Luz espectacular ! Bajo consumo

    1- Luz ultra brillante es increible la luminosidad de este emisor de luz.2. Precio bajo por debajo de la calidad del producto3. Calidad de los materiales es adecuado4. Rapido envío a mi casa.5. Bajo consumo de energía.
    Estoy muy contentento con esta compra, compré 3 de estos productos de diferentes potencias y los instalé en mi terraza. Volviendo de día las noches.
    Compra 100% garantizada.
  • Really excellent value

    This thing is as bright as advertised, and lemme tell you, that is BRIGHT! I accidentally looked at it for a split second and I had retina burn for 5 minutes. Seriously, it is so bright, that for my application (above bed reading light) I had to insert a 2W 30 ohm resistor in series to bring the luminosity down.
    Contrary to what others have posted about these strips (there are quite a few for sale here on DX or varying sizes and specifications) these are "LED modules" and have a built-in current limiting resistor so they can be driven directly (they're 12v so that should tell you something). Consider carefully your choice in brightness on these (lumens) as I opted for too bright. A typical 60watt incandescent puts out about 800-850 lumens, BUT that's in a near-spherical light-cast. This means, that because this is a strip, it is much more directional and you get (for this one) 1000+ lumens radiated to a much smaller volume than an incandescent bulb of similar luminosity.I have also affixed a small strip aluminum heatsink to the aluminum backing as this thing gets very hot quick quickly.
    These things are awesome for general lighting applications.
  • LED module 100W

    posted by Luc6580

    This module delivers a lot of light when combined with the power module 100W.It's easy to fix with four screws on a cooling element.
    The combination with the power module 100W is very good.The module delivers nearly no heat and is very small (120 x55x35 mm)
    The efficienty is very good, i estimate 80 lumen per watt, but is not better than a good TL light.When the efficienty still increases,it will be worthwhile to build it in fixture's for living purposes.The color of the light must also be improved.
