I'm still deciding whether to order this immediately, so as a comparison I checked to see what my P7 set up costs:

Aurora AK-P7-3 SSC P7-C 900-Lumen 2-Mode LED Flashlight $47.75
2 x TrustFire Protected 18650 Lithium Battery 2-Pack Blue $20
UltraFire 3.6/3.7V Battery Charger $12.46
Universal Bicycle Mount for Flashlights and Gadgets $2.89
Total - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -$83.10

I thought the new cycle light looked a little on the expensive side, but after checking the price of my current set up, I reckon it's not bad VFM. Also, as the Aurora AK is on the heavy side for a P7 torch the DX cycle light could weigh less and has better runtime to boot.

Could well be a no brainer
