I bought the Supernova e3 symetrical because I wanted a light that would display the road signs also and the assymetrical didn't look like that would do it very well. I also choose the e3 over the LightOn! because of the 5yr warranty and the fact that I could upgrade it later, either to a new single LED, or even to the triple LED system for (at the present prices) less than you could purchase the current triple for.

I had my first test ride last night (55 miles on dark back county roads in the woods) and while it isn't as bright as a floodlight the difference between this and battery lights is tangible. The difference between this light and a "to be seen" light is the fact that the light doesn't wash out due to streetlamps, or after oncoming car headlights pass you (I always had a problem picking the line back up after a car passed me, not anymore) Also cars actually dimmed their lights when approaching from a further distance away so I didn't get blinded by them. The only problem I have is with the skewer mount and that is because the front wheel throws a shadow going about 20 degrees to the left. On a straight road this isn't a problem but on a sweeping left hand turn you tend to drive into the dark spot. Other than that I wouldn't change my light choice.

I will probably upgrade in the next year or two to the triple light. As much light as the single e3 puts out I would still feel more comfortable on the road with more light. But I have to admit that this is probably adequate for my needs. I would not want any less light so I am glad I didn't go with the B&M lights.

I wish I knew someone around here that had the LightOn light because I like the Hi/Lo switch and it would be nice to make a personal comparison.
