    I know that my planned application was probably not what this light was made for. For human eyes the light is good. But for a camera the powerline frequency reflects in photo taken. You can see this by the 3.5 dark--bright-dark transitions in the photo taken by smartphone camera. Since I only turn on the light for seconds, or less than 2 minutes, the missing heat sink is no problem.

    Led de 50w en 220v direct de très bonne qualité très puissant donc prévoir un réfrigérateur alu voir ventilé le produit est conforme à la description

    Good light output. A properly sized heatsink is needed if you want the chip to last. Fast shipping. Will buy a few more of this chips.
