The Blaster VI direct drive has a broader beam which lights up a much larger area, although not as far as the Spaceneedle. Outside at least, I get to light up a larger area, so if illuminating a larger area without panning the light is important,then the Blaster VI is for you. The hot spot on the Spaceneedle II (second) is brighter, but not as useful as an all around light, but its' good for seeing something specific in the distance. I think they are both nice for what they do, but if I had to choose, I would choose the Blaster VI especially when it's set up for 6 aa nimh batteries. But, I'm sure you will find just as many people who like the Spaceneedle II for it's longer throw and the brighter hot spot. My Blaster VI DD is much brighter after taking out the resistor.
