DealExtreme says: led 12 volt 10watt.
Power = Volts * Amperes
Amps = Power / Volts
Amps = 10 / 12 = 0.83 Amps
With my multimeter I measured 12 volts and 1.56 amps.
Power = 12 Volts 1.56 Amps * = 18.72 Watts.
Theoretically, the LED is 20 watts.
I have bought 3 and all are 20 watts.
This is really strange.
Remains a good LED
