I did the LED headlight conversion, and both sides of this debate are correct. The LED bulb is brighter and pulls less watts than stock bulb, BUT the reflector housing must not be designed to focus the LED light in the same manor as stock. When looking at the LED headlight on, DAY or NIGHT, it's bright but NO focused beam. At NIGHT the LED headlight bulb will NOT have a directed beam of light out in front of you at all, its USELESS. At night if you would just hold the LED bulb in your hand and power it up, you get the same amount of light out in front of you....... NOTHING.
The LED headlight bulb definitely has a much whiter light compared to stock bulb, so it looks COOL!!!
Here is what I do......... depending on my riding plans..... if I'm riding during the daylight I have the LED bulbs installed, if I'm riding at night I switch the bulbs back to stock so I can see where I'm going. I can switch both bulbs back and forth in less than a minute. I have 2 old prescription bottles that both the LED and Stock bulbs fit into and just switch them out, and carry the non used bulb in them in my front storage compartment.
In the picture below, the 80 watt LED is on the left, all the light is just scattered, on the right stock bulb, you can see on the wall how the reflector housing directs the light out in front of you in a focused beam of light.
