can i wire up a dimmer up to each level of my rack with flexwatt? i want to wire them all together off the same plug but if i do not need the lower levels just yet i want to be able to turn them off. sound possible? sound safe? seems like alot of extra wiring going on but i dont want to get caught with my pants down and need an extra couple levels. i also do not want to have the tape running if i do not need it.
