No comparison with both on low beam. The LED equipped bike had more light on low than the standard light on high beam.
What impressed me was the light spread from the LED on low beam.
Like Mike said, the price sucks and until it comes down I'll stay home at night.

That width of projection was something I immediately noticed on Travis's bike. The spread from those side projectors really was impressive. Could live without spotlights with that spread.
The price is high. The 20% off shops are around $420 if I remember right. When the HIDs first came out with the digital ballasts the kits were close to that. The red bike at the time, however, was just dangerous to ride at night. So I sprung for what was the only option at the time that was sure to make it good. But I do ride at night some (enjoy it). So the safety from the improved light wasn't just a conceit.
As much as the cost of this LED light is a consideration I've been significantly surprised by something relative to that cost. A company called JW Speaker is the OE for the light. They sell the same light (or at least a very close approximation of it) themselves. That light and its siblings in their product line are marketed to over the road truckers, military applications and other places where good and/or heavy duty equipment is a necessity. Harley sells it cheaper. Even at Harley MSRP the light is significantly cheaper than dealers for Speaker offer the light to the other markets.
Speaker had products that were comparable to the the dual bulb Halogen reflector on the SEUCs and in the P&A book and a few other pieces we'd find familiar. None of those seem to have the price variation that this one does. Can't help but wonder which happened: Did Harley swing a significant deal in the purchase contract for these lights or did Harley buy some "lesser" version of the light than the Mftr. is offering to other markets?
