Long runtime is extremely valued in lights during emergencies. Super bright lights that last one hour become useless.
Having a number of levels doesn't have to be painful. My hotwire regulator has about 100 levels, and all you have to deal with is up and down, so you don't really care how many levels there actually are.
Why do people keep having difficulties grasping the fact that HIGHER DYNAMIC RANGE = LOWER EFFICIENCY?
The higher the difference between the highest and lowest level is, the less efficient the driver will be. That's just the way things work, folks. You can't have the cake and eat it too. It's either-or.
I agree with orcinus and AardvarkSagus 100% and another reason this light would not be my first choice when trekking to the bathroom at night,imagine dropping the L2 on your bare little toes ouch!!:laughing:
Why do people keep having difficulties grasping the fact that HIGHER DYNAMIC RANGE = LOWER EFFICIENCY?
This light was designed to be efficient at high output, which is why there are 3 cells in series powering it. As you lower the drive current to the LED, the efficiency will go down, due to losses in the driver circuitry. Even a small amount of dissipation in the driver becomes more and more significant as the voltage across the driver increases. The math (and physics) are not very complicated here.
Hey guys?
If it's so easy where are all the high powered MC-E/ P7 that have a 1 lumen or less low and ranges up to and beyond 500 lumens,I don't see any and I doubt you will see one any time soon :devil:
Exactly! therefore it would be pointless at this time to add a 1 lumen level for the sake of efficiency IMHOLooking at energy consumption it might also be pointless to make it, because the control circuit might use more energy than the led at low power levels.

I'd bet there'd be an equal amount of people whining how inefficient the light is if it were the other way around - i.e. if the light did 1 lumen to 750 lumens. Just look at the Arc6 threads.
