I was able to nicely light up 4 15 w CFLs in parallel. The difference in
effort is obvious as you go from one to three to four bulbs. I have in mind
using this with kids. I am going to lay it out with open wiring and knife
switches so the parallel circuit is visible. The bulbs are polarized in the
sense that they are an open circuit (probably a diode in the ballast
circuitry) when you turn the crank backwards. The bulbs use ordinary light
bulb Edison style bases so you have to be sure you don't inadvertently
connect them to 120 VAC.
