In the latter case, it turns them all on simultaneously. In the "low power" mode, it lights each candle in sequence like this (example for day 5, 0 being the first day): 0000 0 0001 0000 0 0010 0000 0 0100 0000 0 1000 0000 1 0000 0001 0 0000 0010 0 0000 0000 0 0000 0000 0 0000 (repeating...) In this mode, only one LED is active at any time, though the sequence is not visible to the naked eye (each step in low-power mode is only a few milliseconds). It also lights them out of order since the shamash comes in the middle of the sequence. :-) Looking at the source code menorah.c, it has a “low power” and a “high power” mode.
