You claim that KosherSwitch® “pays for itself” in under a year. How is that possible?

The alternatives to KosherSwitch® are all relatively wasteful:  1) Leaving the fixture on for the entire duration of Shabbat and/or Jewish holiday.  Obviously, this is extremely wasteful, since much of the time that the fixture is turned on, it’s not in use (such as overnight).  2) Timers and Shabbos clocks: Since they need to be pre-programmed with the anticipated schedule required, they will always include wasteful “buffer” time before and after the actual use.  So while you’re sleeping in the bedroom, the dining room lights are still illuminating an empty room.  (If an air conditioner is active in that room, it will be double the waste, since the unit will continue to work hard cooling a room that’s vacant!)  KosherSwitch® eliminates this waste by allowing the on-demand control of electricity in a manner that’s permitted.  So electrical devices go off soon after they’re no longer needed.  See the Energy Savings section for further information, including a sample calculation of the electricity savings possible.
