Accepted Answer

Yes, as is often the case with electronics, there will be a slight draw even in the “off” position. This fixture has a parasitic loss of 0.002 amps (tested at 12.6 VDC).

To safeguard against battery drain, typically a battery switch is used in marine/RV applications to protect the batteries during extended periods of storage.

Will it be a problem for you? As a simple exercise, a typical RV deep-cycle battery is rated at 80 amp hours. Using 50% rated capacity or 40 amp hours, one reading lamp would deplete one battery to 50% in 20,000 hours or 833 days.

Accepted Answer

The same switch controls both. Touch once and the night light turns on. Touch again and the reading light turns on (and the night light stays on). Touch again and both lights turn off.
