I have now experimented with the Zongshen LED headlight, and three different bulbs in the stock headlight.
I have used the stock HS1 bulb, an H4 incandescent bulb, and my latest experiment is with an 18W, H4 LED bulb I bought from eBay.
You can purchase this LED bulb from China for $14, delivered. Because I didn't wish to wait, I purchased the bulb from the United States for $21.
Cyclops is selling this LED bulb for $60, plus shipping, with a 1-year warranty.
