The only problem I've seen with the HD LSs, at least to me, is the X-box beam shape with the collimator. Maybe for others, beam shape isn't high on the list, but I'm pretty judgmental when it comes to beam quality. Other than that, the throw is very good, and a 5W white, being so bright and its die so large, migth reduce the X-box effect...
I wish they would use the acrylic balls for reflecting light (or half an acrylic ball if it still works)... Now that would be an awesome spot from either an HD or LD that really carries...
