    Two 5W LEDs in series (6,5V+6,5V=13V), which makses it suitable for connection to a 12V lead battery, which is kept at little above 13Volts with continuous charging. I have used several pairs of these for getting light into a storage room. Use of pairs of 5W LEDS instead of 10W LEDs give better... Read more

    -Good quality on all the ones I've gotten(~10) -Quite powerful, don't look into it even without lens .. It'll hurt your eyes. -Double pads for positive and negative terminals makes for easy wire-routing in more advanced setups. -Most lenses/reflectors seems to fit this emitter quite good, my be a...

    Cheap Very Bright (Even running them well short of 5W) Easy to use Nothing really Have patience while soldering, with the star it takes a little time to get hot. Also be careful because the heating of the star can cause the solder that holds the LEDs can get soft. Almost a pro actually due to Ran... Read more

    The LED's themselves are very bright. I have found the following. Soldering to them is weird, using a 18w soldering iron, the solder would take a while to melt, then when it would melt and stick to the pad it would cool for a sec. I imagine this is because of the heatsink star they are attached I... Read more

    As noted in another review(s), it gives off a lot of light for it's size. I got it in October of 2010 but finally now got around to setting it up. I hope I was sent the right one. All the heat discussed in one or more other reviews is no longer a problem and I can safely touch it after it's been... Read more

    This 5W LED Emitter is better than I figured it would be. I have a tactical flashlight that had a 7 watt led on a star, it lasted less than a week ( think I put the batteries in backwards) (which I think was a Q5 being over driven with 7.2 vdc) I have to say it is almost as bright. I put a 12~24... Read more

    Good bright LED for DIY projects. -Bright -Allmost the brightness of 2 x Q5! -Good value Should come as bare LED. Because when you want to make a multiple LED flashlight you need to get the led of the star. I made a flashlight with 3 of these LEDS inside. Very bright but also very floody. And I I... Read more

    Excellent item. Bought three, all work and they've almost left me blind. They're too warm. Even with thermal compound and a good aluminium disipation plate. I think maybe 50-60 Celcius degrees. I would like to see how long they last. I was driving 2 of them with a 13v power source and a serial I... Read more

    WOW this thing is BRIGHT. I have driven it up to 1A(~7W), and it rivals P7/MCE brightness at the same power levels. However, I don't know if it can handle 1A for extended periods. You can clearly see four dies beneath the phosphors. They're wired 2S2P, which is a great way to wire them since many... Read more
