cob led module Customers Reviews

  • Very bright and affordable

    posted by gamei56

    Very cheap, very bright, positive and negative terminals clearly labeled, nice notches around.
    Out of the three I ordered, one has failed. Not sure if these are reliable. I use these with an LED AC/DC driver that was somewhere on this site. They are very bright and the viewing angle is not very wide, so for spotlighting purposes, these are good.
    If you need a cheap and powerful LED, get this and get a heatsink with some thermal epoxy or drill it in nicely.
  • strong light source

    Round plate with 20pcs LEDs lit intense warm light. Luminous flux is about 70W clear bulb. Beam angle of 100 degrees estimate. She has a lot of heat, it is necessary to place the radiator. It can be screwed for the center hole. Isolate the screw, there is short supply pads. Covering plastic layer is soft to the touch. Rather put LED module cover glass. CAUTION: do not look directly at lighted plate, it hurts your eyes really shines a lot.
    It is an efficient light source with high power. I will powering 12W LED constant current cource cower cupply driver 300mA (SKU 81770). Lit perfectly.
  • Perfect for ceiling lighting

    posted by TechJunkie2

    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 strong light - 100 emitters

    posted by yarash

    Very strong light, the specifications say it hasOnly one emitter, but it actually has 100 of themEach peace has on each side the (+\-) so it is very easy to solder a few peaces in a row.Very good build quality
    It is not obvious to me that if i buy an LED That i need to add more equipment other than just powering it.
    Very high quality, but needs some way to cool it down
  • Cheap, bright, essy to use

    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
