fyi, both Niterider and Cygolite officially announced new lights for this year that double the light output of last years lights at the same retail cost. I know some of the new models are available now, while others are supposed to be available to purchase over the next month or two. For example, my local shop Freewheel Bike just starting letting people order the "CygoLite ExpiliOn 400 USB Rechargable Headlight" -

While REI sells last years "CygoLite ExpiliOn 250 USB Bike Light" for $130.

Just an fyi. I know Niterider doubled the light output on almost all their lights, while pricing the new ones that same as the old ones as well.
