In a heavily saturated market of headlight led kits it can be difficult filtering through the abundance of exaggerated claims and false advertising. Using power formula Power = Voltage times Current (P=V*I) we can can calculate the real power draw of a globe.
Most headlight LED kits have a current draw between 1.1-1.6A @12v, which equates to an average of 20W. Supernova V4.0 boast a staggering 3.0A of current @ 12v, producing a tsunami of light whilst operating at cooler temperatures than many lower powered LEDs thanks to 

Unlike traditional low powered headlight LEDs, the current is high enough on the Supernova V4.0 to satisfy most canbus systems without the need of further resistors or decoders.
