If 60.00 is drop dead price, I would look at getting a romisen light w/ 18650 cell / charger which will still be under 60.00 in price w a lockblock to mount the light.. a 250 lumen Q5 will still blow away a 2watt led..

The new romisen is quite nice.. the RC-C8 II Flood to Throw light.. Fully adjustable from wide flood to tight spot.. Long run time, 3 modes.. High - Low - Flashing.. This light also can use 3-aaa cells.. Have not done runtime test on 3aaa cells..

The flash mode is very useful, about 120 flashes per minute, not close to seizure inducing like many other lights.. The light itself is a little big for helmet light but is still doable..
