It sounds like you need the new heftier D-size lemons. :-) Seriously,
you should try to put lots of lemmons in parallel, to increase the
maximum currant capability. Use as wide a set of plates as possible.
Perhaps you might be willing to substitute a 100 uA meter movement for
your 2.2 mA bulb. It would certainly be easier to drive.

If all else fails, you could always hide a small hearing aid battery
in one of the lemons. :-)
