cob yellow Customers Reviews

  • Cheap, bright, essy to use

    posted by lechn

    Very good quality spot led device! Must be driven with constant current 300 mA at ~ 30V. Makes a good pair with the driver 102691 (12 W 300mA, 20-48V), although some flickering can be observed when fed from this device. Gives a very bright, warm light, the color temperature is much like an incandescent bulb. Can easily be fixed to any surface with three 4mm screws (and nuts).
    Gets reasonably hot when on, it's normal. Should be tightly connected to any flat metal surface with some thermal paste, not necessarily to the heat sink. High temperatures shorten led's life!
    Cheap, reliable, easy to use, very bright, warm light
  • Very Bright LED

    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.
  • Super bright

    Very bright. Whole lotta light in compact package. Very nice finishing.
    Heating limits use since you have to be able to provide cooling. I tested with 12v and after couple minutes I got some smoke. Might have been also from the surface I tested with and cut the power in that point. Hard to tell was it the item or the surface, since cannot see because of the great brightness :).
    Usable, compact and bright light for short period lighting and for long time usage if cooling provided.
  • Nice

    This led is a really powerfull light source. Well balanced, noflickering, no strange greenish color. It works very well to me.
    Hadle with care, it is NOT a toy led. It is a really powerful led that gets hot and needs to be handled carefully.
    It's really useful for me. I have changed a 300W R7s lamp with 2 units of this led (2x20W) and now I get more light ... When I recover the dimming capability it would get great!!
  • Perfect for ceiling lighting

    Nice very bright light output and nice colour temperature. Leaning very slightly towards yellow it emitts a light similar to that of an incadesant light bulb. I have installed it inside a ceiling light that I purchased from Ikea (2.99). After stripping out the electrics the LED disc could be perfectly seated/Glued with themal paste) onto the metal structure of the light housing. This along with a 15w constant current regulator SKU186293 (Glued in place with epoxy putty) provided a perfect replacent for a 60w incandescent light bulb. It's been running for 3 months now with no over heating problems (Just the light housing to disapate heat) and provide enough light to fill my large bedroom.
    perfect replacement for incandescent light bulb.
    This is a high poered array of LED's housed on the same substrate. It gives of a lot of light (not to be looked at directly) and requires diffusion. Get this if you know what your doing and are handy with a soldering iron. You won't be disapointed
