Finally got the LED right

Just read this a Cyclingnews.

Dinotte Ultralight

Dinotte's aim with this compact, high-power single-LED light was to make the ultimate front light for road bike use. While mountain bikers like the huge light output of HID and multi-LED designs, what you need for road cycling is lots of light, in a compact, low-weight assembly. To that end Dinotte uses a five-Watt Luxeon LED powered by four rechargeable AA cells that sit in a pouch under your handlebar stem. The whole shebang weighs just 200g, leaves spots in your eyes for several minutes if you're foolish enough to look straight into it and has a claimed run time of 180 minutes in low power mode and 100 in high, with 2300 mAh cells./JS

MSRP: US$249.99 (with 2300mAh AA cells & charger), UKP119.00 (without batteries or charger)

I think is the wat to go for road cycling, commuting and night cyclocross training. BTW. I'd go with the version without batteries. You can pick up NMih batteries and charger for less than the difference at many places.
