If you are just doing tabletop smaller object photography, using more than one light complicates things greatly... (One light more tends to overpower the other and is harder to get good lighting ratios...)

The basic lighting rule is; Key/Fill/Effect, which one light is dominant that provides and brings out the form of the object (Key), then spots of contrast that are too dark (and can exceed the film's range are balanced (Fill), and if some other lighting modifier is considered, like a light with a color gel, a background with a pattern, accents etc (effect)...

With a single light, you would choose a light angle that brings out the form of the subject well, but since the light is close, you can fill the holes with different reflector cards from hard/bright (foil), white, grey (for slight low level) even black (so reflective areas "see" something dark to reflect)...

I have a lot of pro lighting gear, but will use a cheap reflector clip-on painters light on an inexpensive microphone boom stand with just a LED or CFL bulb (for B/W) as a small set key light, and use reflectors for the rest... Easy and does not overpower the subject... And does not get hot...
