  • Very Bright LED

    posted by csei

    The LED strip was brighter than I expected it to be. Gives a nice warm colour. Easy to solder to pads and has pads each end so was able to connect multiple units easily.
    I do wonder how long these will last without heat sinks as the heat cant be good for the LEDs.
    If you wont them buy them, good value.
  • Very Bright White Light

    posted by valveman6146

    Light is very bright. When operating fully, you cannot look at the light. Has even spread. Does require a heat sink or it may burn out quickly. I operate these at just under 14VDC and about 1.4A. Adequate heat sink is require if running at this level of current. A great item for a worklight and even video/photogaraphy. Lowering the voltage will change the colour temperature into the 3000K.
    An excellent LED at an incredible price. Very loow power consumption for the amount of light it puts out.
    You have to get these if you are interested in running lights that require low power consumption. Great for RVs, Camping, Trailers, video and photography.
  • lots of light

    a lot of light comes from this strip. Dimmable with dc dimmer.Works fine with 12DC
    Maybe it's possible to make the light warmer with yellow or orange filter foil.
    Energy saving strip with a lot of light, even with only 10Watt. Personally I wont use it in my livingroom because the color is too cool, too white. But somewhere else it wil be a perfect light.

    posted by Tareka

    Great light output.Does not need special driver ~900mA @ 12.3 volts.Good compact size, Far more useful than the size suggests.
    Will be great as fixed lighting in my camper trailer.Will also try encasing the unit in epoxy resin to make connections waterproof for under water lighting.
    Very good value for money
  • Warm white sun

    Bright! The light gives off a pleasant warm white.Made a ceiling lamp from five of these and it's almost too bright.The shape of the element is especially suitable for making of light sticks suspended from ceiling.
    These LED lights require mandatory cooling. You need to make sure to keep the LED element under 50C to maintain low current consumption. At 100C the current doubles, but emitted light stays the same. You need to provide about 100cm2 cooling surface per lamp of minimum thickness 2mm. Use silicone heat paste to improve heat transfer. A viable option is 30mm square aluminum tube with 2mm wall thickness, allow about 20cm of the tube per LED light, 5 elements per meter, temperature stays about 45C (25C over ambient)
    The prototype worked out excellent. Just bought more elements for two more lamps.
