If you exceed that, you need to wire the pole to something (even if it's a bigger panel somewhere.)
Given the LED lighting composition made up of individual LEDs, it should also be possible to position LEDs and lenses to make trail lighting that lights a rectangular area of the trail, rather than the usual fully circular area, where much of the light is "wasted" on the trail surroundings. This, in turn would reduce the power requirements (and battery capacity requirements) for lighting the same amount of trail.
I don't know whether anyone makes such trail-optimized lighting, though.
