  • Very bright LED

    posted by flopezr

    The intensity of light produced is surprisingly high.
    Increases battery life because it consumes very little electricity.
    Its size is incredibly small.
    Its price is cheap at DealExtreme.
    I wish it were warmer white light it produces, though of course this is a matter of personal preference.
    The order took a long time to get home.
  • Best/brightest LED emitter I had so far !

    Extremely bright.Very nice color, not greenish like other "warm-white" LEDs (like the 50W Prime emitter), but I would call it more daylight-white. Looks like hot halogen lamps, very nice and pleasant to the eye.
    I bought 4 pcs to replace my halogen uplights, because one of them exploded and covered me and my gf with hot glass debris. I used a heatsink with 200x200x25mm and added a 60mm fan at extreme low speed, otherwise I got over 90°C on the heatsink. With the slow fan I get about 60° on the heatsink and about 90° on the LEDs, which is perfectly fine.
    As bright as a 250W halogen lamp. Really the first LED emitter capable of replacing halogen uplights !Make sure you buy the matching LED driver and a really big heatsink, you have to get rid of 75W of heat (at least the Cree specs say that only 25% of the power is producing light)!After these I also bought some of the 50W emitters (with only 10 LEDs) for the bedroom.
  • Very bright, and pretty good quality

    The led is really bright, the shell is solid which gives the led a more tough feeling feeling. The light color is pure white.
    Pretty good led, easy to install. (+ = the side with a litte nib out of the metal.) You should go for something around the 3.7volts and 0.65amps for a power supply. I used 3 AA batteries and a 1.5ohm resistor.
    Worth the money I am probably buying more of these soon.
