Personally, with a collection of roughly the same number of plants, I just use the LED lights that Ray sells on his website. They screw into any normal type of lamp used with regular bulbs... I have one of those 5-armed bendy lamps so I can adjust where I want the light centered. It works quite well for now to cover two tables of plants. Once my collection grows I will need to adjust to something bigger, or just more of the same type of thing. 2-3 bulbs should probably work well enough.
Here's the link to the bulbs:
