It's a bit more complicated than that...
Yup, I really like the look of them, and could be tempted, but I can't see they'll ever be the only pair of lights you'll need, especially if you need lights to see by, rather than to been seen with.
They claim to project forward 134 lumens. The Hope Vision 1 (a favourite with night riders) claims 240 on high power - and I know that most don't use them on high power.
My biggest quibble would be that the light they project forward apparently isn't directable.
