So far I don't think anyone has been able to mate BSF in artificial light. I'm pretty sure some have done it in greenhouses though. BSF mate in flight so they need at least a little flying space. I think I've heard about 10 X 10 ft enclosures being successfully used.
Even without indoor breeding there's no reason you can't compost with BSFL. They should do well in the summer up north and you can extend the function of a colony right through a cold winter with some simple insulation. If you're curious you can read about winter bioconversion at ESR's website:

During the hot summer months, overcrowding can easily occur, and this overcrowding gives rise to relatively high temperatures within the unit. In order to cool down, some actively feeding larvae are forced to exit the unit. This migration continues until the density of larvae and temperature within the unit drop to an acceptable level. But during the winter months, larvae can thrive in very large numbers without overheating, and as the mass of larvae increases in winter, so too, the amount of waste consumed within a given unit. Paradoxically it would appear that this bioconversion unit functions far better in winter than in summer.
