What is the difference between this headlight and the Evolution speaker headlight besides the big price difference?

The Speaker headlights just seem to have a bit more focused beam than our Revolution lights. Clearer top and bottom cut off lines. Our light are a great runner up, and are a lot easier on the budget. If you have to have the BEST, buy the JD Speakers, you won't regret it. If you still want great LED headlights, just not the price tag, the WH Revolution light are hard to beat for the price.
