    Cree XHP70 test

    I got a XHP70 N2 bin ad made some quick testing. (In 6V configuration)

    -Soldered the heat pad to 1/8 square copper tube.
    -Built a crude lux meter with a LLS-05A linear light sensor
    -Ran the test with icy water cooling.

    Here's the data:




    At 9A the LED is eating a whooping 63W.

    The 1/8 copper tube is a bit narrow for the heat pad, next, I will solder the LED on three 1/8" tube side to side so the + and - pads are sinking heat as well.

    Made a better heat-sink:



    And the results:



    Pushed the LED to 10A, the heat-sink topped at 32C and Vf was 7.28V

    Theses preliminary tests look good for my next project:

    Excellent work, Hugo! So mind blowing that you're pushing over 70 watts through a single LED!! Who would have imagined this would be possible just two short years ago??

    4000lumens each long reach spot lights with optional aspheric attachment for ultra long reach. The pictured pair weight only 120g including wiring and driver (RC6Flex). Built for SAR drones or similar applications.

    BEAUTIFUL! They look very polished and ready for production. You ARE selling these, right? And the RC6Flex driver is built in, I'm assuming?

    Not yet, but will. Now the RC6Flex is standing alone with a length of cable between the driver and lamps. The driver could be build-in as well.
