I ordered 10 watts. After checking, I can say for sure that these are not 10 watt LEDs. Really 3 or 5 watts. At 8.5 watts, the voltage across them becomes 33 volts, and it is not realistic to cool them to an acceptable temperature. If you give 5 watts, (voltage 30.8 volts, current 0.16 amperes) then the led diode becomes more or less acceptable temperature. So the conclusion is that they sold me either 3 watts or 5 watts LEDs, but they wrote that 10.
