Cateye Double Shot as main headlamp?

I already have a Blackburn Quadrant as an LED headlamp with various
steady and flashing modes but it's not bright enough for dark roads or
off road at night. I need another light and am tending towards a Cateye
Double Shot. Can anyone say if this combination is good enough to go
off road or on dark country roads safely. I'm happy to use it as a
helmet light if that's the best position. Wish I could afford the Pro
model, but that'll have to stay a Christmas wish.
