For example, VQ (6) + LFL 10 S means 6 very quick flashes followed by a long flash, during a 10-second
interval.
The amount of power your lantern draws through the night depends on the duty cycle, i.e. the amount
of time on as a proportion to the timing cycle. For example, 0.5 seconds on and 4.5 seconds off equals a
10% duty cycle.
It is best to operate at the lowest duty cycle appropriate to the actual needs of the application.
