I'm trying to hook up a lamp of growth to an export bus but it doesn't seem to be working. This this expected? can i hook up my lamps to my thaumic/ae network and pull essencia out of it to power my lamps?

Lamps use the suction mechanic to refill themselves. Two options:

1. Export bus -> Warded Jar -> Tubes -> Lamps
2. Essentia Provider -> Tubes -> Lamps
