The LED is finally able to produce enough light to be a viable headlight bulb. Instead of placing surface mount LEDs around in a circle, our design uses dual 180 degree CREE emitters on both the top and bottom of the 'bulb'. The center of the LEDs are in exactly the same place as where light comes from in a standard Halogen bulb. So what does that mean? It means that the light projected from the LED array will hit the headlight reflector exactly the same way your halogen bulb does. This is important.
The regulated power supply uses an H4 connector and is plug and play to the bike. This unit supplies power to both the LED array and the fan. The fan is simply to create a small amount of air flow, not to chill. The fan screws on to the back of the 'bulb'. A spacer is included for the fan to keep the blades clear of the headlights rubber cover.
The LED design is instant on, no flicker and unaffected by temperature and power cycling (when your headlight is turned off by pressing the starter button).
So how does it compare to the stock Halogen bulb?

I just ordered this and will be doing an install report when it arrives.
