Yeah, I originally got the Magicshine because the 45 minute to 1 hour runtime on high for the P7 flashlights turned me off - not really quite enough for my commute. However, as it turns out, 1/2 power mode on a P7 flashlight is more light than I used to get out of a 20 watt halogen on a 12v SLA, and is plenty, and at that rate I can get close to to hours on high, or easily cover my 48 minute winter commute even with the battery degraded by the cold.
