I tried it with a larger filament bulb but couldn't get that one to light (both bulbs are shown in the attached image). Not sure how significant this is, the bulb lights to the same brightness when connected directly to the charger output so this is sort of a round-about way of doing the same thing. I was surprised it would work this way though and would be interested to hear any thoughts or comments.
cheers,
