I think it is a 10x16. I store the bigger stuff up top in the rafters and the smaller pieces in a cabinet underneath my spray adhesive pull out drawer. That is under my assymbly table. I just use 13 watt energy saving bulbs. I have various lights around the shop from like lamps. It is pretty cramped in there. And hey slowcutter, my new shop- vac does the trick good, that's why you don't see any saw dust.
