If your light seems rather dim than maybe it needs more juice. That’s what I was told by a coworker as he upped my switch to a 20 amp at a bargain clearance price. Although I changed out the 15 amp switch to a 20 amp which allowed more juice to flow it didn’t make the lights brighter or the slight fan hum to dissipate. Besides it wasn’t the lights lack of brightness that prompted the question it was the hum of the fan. But in either case the more juice given the brighter the light or the quieter the hum. Too much juice can cause a short and burn the light out, because lights are not capable of an imbalance in the flow of energy. So this is where balance comes in and churns the cream into butter to smooth on the bread. We churn life and find balance as long as we enter the once empty room and learn to love the calm not boiling till nothing remains except sediment. Hum is a vibration that can be pleasing to ones innards creating a soothing effect which brings about a pleasing Spirit. When ones Spirit is pleased the dim switch is no longer dim, but churns love for life and hums, not being overloaded or out of balance. Energy flow is a pleasing effect on ones body that is not easily understood at times.
