Initial indication is that the beam pattern is a bit strange. The beam is strongest in a small square in the center, with a wide pattern without much vertical dispersion. Looking into the lamp is absolutely dazzling.
This first photo is the low beam setting compared to the beam cast by the single 3 Watt Luxeon LED installed in the Sunbeam S7. There's a big difference in intensity. The single Luxeon is feeble in comparison.
This second photo is the high beam setting on the Truck-Lite headlamp. (The single Luxeon was turned off in this photo). There's not tremendous difference as captured by the camera, but in person it is a very intense light. The brightest part is very focused, and the dispersion away from that point is rather poor giving very intense light only at that specific point. Ride to work on Monday morning should provide the practical nature of this LED headlamp.
