Anonimus35, the number of actions listed for Khanate lightbulbs seems low. Also, the actions taken to convert the coins into lightbulbs really lowers the efficiency. Instead, the same coins produced in the Black loop can be exchanged for Crackling Devices for no actions at the Midnight Market, sold at the Rat Market with a markup (same with the Vital Intelligence), exchanged for Lamplighter's Beeswax, and upconverted to MoL.
