Kathleen:
We have a similar problem but for a very different reason. We
are in an old building that was built with lots of windows to
take advantage of natural lighting. Even state-contract
industrial shades only bring the lighting down into the region
of pleasantly-dim.
I would look at nothing below 1000 lumens; at present we are
trying to find 2000 lumen projectors that are within our budget.
Good luck.
