Steady beam. I opted for the Specter-driving which gives a good side and forward spread.
Worth the $$, hard to say. I mainly did it for evening autumn/winter rides home from work; I am not a night rider. However... I live in a semi-remote area that seems to get less remote all the time. Tonight, I was able to use only about 20% of the time, maybe. Everyone seems to be driving at that time. These lights are so bright that they will blind oncoming traffic. You must be willing to shut these off far from oncomers (a word?). This leaves a long dark gap. Damn; and generally in the worst areas.
When you can use it, it has a great spread. When not, it is irritating. I'll post a comparison.
