white led module 10w 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
  • maximum light, maximum heat, minimum life

    so much light, so so so shiny, you can be blind, you can think that you can use one of these in a room on evening instead of regular ceiling lamp.
    you have to use it with extra heat resistance otherwise inner small leds in the COB led can easly get burned one by one. Mine Leds got burned.
    it you know how to use it with heat resistance and with low voltage and low amper, buyit they are perfect for you. Otherwise they will be a short life.
  • Bright Warmtone Light Strip

    posted by processman

    Very Bright Warmtone Light Strip . Possibility to dim the light level through special dimm circuit (Current Regulator with LM317)is very usefull. I use it as work desk lamp.
    Very good warm tone color for desk top lighting .good homogene light emission , Only 9. . 10 Watts power consumption but light like 80 W incandescent bulb. Dont look inside it when it lighis at max. power it may disturb your Eyes and over all u see it "I" 's
    I can recommend it for especially those people Who needs bright desktop lamps. Good replacement for 20W fluorescent lighting.
  • Excelent quality power led

    posted by mrdevil831

    Warm white, good light, very good eficienty, starts working at about 6v. I think optimal eficiency would be at around 9.3v.
    Color temperatoure couldbe a little lower.
    A nice high power led at a very good price. I recomand this for hobbyst that like to experiment with low power and high eficiency.
  • So Far So Good

    Incredibly easy to solder due to the extended legs with through holes. Quite bright. Cool runningSeems to be the correct colors for plant response
    I received 4 of these just a few days ago. Currently running a 19.5V constant voltage supply, 3.3 OHM (10 W) resistor, and then two grow lights in series. The lights are affixed to a 3/8" thick plate of Al with an old P4 heatsink on the other side. Ran for 8 hours with minimal heat buildup and the basil seemed to respond well (went from curved towards the window to vertical while on)
    Much cheaper than purchasing a combination of 8 red and 1 blue LED, and so far seem to be functioning as expected.
