  • Really excellent value

    posted by AlphageekYVR

    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.
  • Phenominal LED Light bar!

    Does not generate too much heat (but it still really does need a heat sink). Light output is simply unbelievable! Very bright for such a small package size. Great for RV's or campers or any remote place where you only have 12V power.
    Excellent light dispersion from the strip - great for general lighting!
    A fantastic deal for the size and power draw and the amount of light it puts out. Best I've seen so far for LED lights!
  • 10W 3500K LED Alternative...

    very bright 3500 K light when driven at max spec of 12 V and 900 mA... less bright and warmer 3000 K light when driven at 650 mA... cheaper alternative to the other 900 lumen 3500 K LED chips offered on this site...
    you can over drive these chips with slightly higher current... definitely do not try without a heat sink as it will fry even faster and potentially go into thermal runaway... have over driven the chips to 1050 mA with proper heat sinking...
    better value LED chip than the other comparable ones on this site...
  • Nice and bright

    Very bright, does not heat too much, and good solder adhesion. Ver Ideal for diy use.
    Great, glad that I decided to buy this led! Will be using as main light for my lightly planted fresh water aquarium. Therefore will be enclosing it in a thin piece of glass.

  • Very bright LED

    Still experimenting with it, trying to find best way for implementation. Very bright, can be used for study desk for learning and reading.
    I tested it with vaious types of powers, from 12V to 14V, it seems that all values of power leads to same degree of heating.
    I will be back when I finish testing and implement it finaly.
