  • So Far So Good

    posted by jlinnema

    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.
  • Daylight LED...

    high-output relative to the colour temperature... convenient cob panel allows for easy heat-sinking when driven at maximum current... good light beam divergence...
    used two of these to retrofit a burned out standing torchiere lamp... powered by an old 12V 1.6A switching power supply from an old networking appliance... if you've got standard ceilings, two is probably all you'll need... might need to add a third panel or a diffuser to spread the light out more if you have very high ceilings...
    great component for retrofitting to LEDs...
  • Really excellent value

    This thing is as bright as advertised, and lemme tell you, that is BRIGHT! I accidentally looked at it for a split second and I had retina burn for 5 minutes. Seriously, it is so bright, that for my application (above bed reading light) I had to insert a 2W 30 ohm resistor in series to bring the luminosity down.
    Contrary to what others have posted about these strips (there are quite a few for sale here on DX or varying sizes and specifications) these are "LED modules" and have a built-in current limiting resistor so they can be driven directly (they're 12v so that should tell you something). Consider carefully your choice in brightness on these (lumens) as I opted for too bright. A typical 60watt incandescent puts out about 800-850 lumens, BUT that's in a near-spherical light-cast. This means, that because this is a strip, it is much more directional and you get (for this one) 1000+ lumens radiated to a much smaller volume than an incandescent bulb of similar luminosity.I have also affixed a small strip aluminum heatsink to the aluminum backing as this thing gets very hot quick quickly.
    These things are awesome for general lighting applications.
  • Very bright and very hot

    Very bright, does not heat too much, and good solder adhesion. Ideal for diy use.
    Will be using one of the main light for my lightly planted fresh water aquarium. Therefore will be enclosing it in a thin piece of glass.

  • 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.
