  • Shiny!

    posted by adlerweb

    Bright! Really. Can easily compete with my other 25W-LEDs. Dimming using PWM works quite well. Input voltage is perfect for car or other lead-acid-battery-systems (e.g. solar).
    Dont forget to add proper heatsinking if you want to use is over extended periodes on full brightness. I used #35816 which is suficcient for my environment. It has only (gold-plated?) pads without holes so you should know how to solder
    If you need a lot of light using not much power this is your product.
  • 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

    very gooooooooooooooood light and so much easy to install . Very bright led .low price .it is perfect to use in DIY system .very low consumption .
    high-power LED is very efficient, Very good luminance compared to normal 70w light bulb don't create a spot like the normal spotlight . The luminance is very smooth.I realized that really, I mean really, diminished the electricity bills by replacing the halogen bulbs with LED bulbs
    very good quality and quite cheap compared to their counterparts of the same quality .
  • Very nice

    Arrived in dark grey foil package. Good price. Color temperature of 3000K seems to be right, warm white light. Measures 10,0 x 0,9 x 0,3 centimeters (sorry for the metric system, I'm from Europe).Connection points on both ends work fine, might be useful.
    Aluminium heatsink might not be sufficient enough. I didn't measure it though.
    Very nice and original DIY part for projects.
