The 10A one fits easily into the front pocket of (my now 4 sizes too big ) cammo jacket, if you have a lanyard on your lamp then it's easy as you like to jump in and out of the car with the lamp and battery ready to go.
The only thing that slows me down now is brushing my dog and wiping his feet before I let him back in the motor :kiss:
I've been well happy with mine, yes they are expensive, but they are as light as fook! Technology costs I suppose.
If you take me out one night, then I'll let you play with mine ................
