    Good quality. Very bright LEDs. White LED draws the recommended 1.05A at 11V and warm LED at about 11.1V but this depends on their temperature, I recommend suing a constant current source for full performance. Also a very good heat sink and thermal paste is required as these LED get very hot very fast, even on a large heat sink the LED will reach over 50°C.

    was a little shocked at how bright this led is. It would rival say 3T6. It is operable from about 4vdc on till 12 vdc. It can go much higher but it gets extremely warm. when one grid goes down it does not disable the entire array. However you look at it, there is some differentiation in the output of cells within the array and no 2 cells fail exactly the same. I had 3 fail at 13vdc on startup and several more fail at 12vdc while the temperature was stabilizing.

    Good LED. I try it with PWM controller, on 12V input, D=3/4 is very hot, over 70°C (with small heatsink).

    Ottimo prodotto, testati tutti i led e funzionano perfettamente, luce molto potente ma scalda davvero molto, necessario dissipatore in alluminio. Banggood ottimo per gli acquisti e spedizioni veloci!

    Nesvítí tak silně jak předchozí led.

    Fonctionne très bien, prévoir un bec puissant les led consomment plus d'1A sous 12V.
