2 room flipflop relay

[kushman45]

Hey like I said go ahead but i got my electronic technician certificate from the military and hid bulbs is what we used for perimeter security so i did deal with both HPS and MV system everytime we had to setup a new perimeter for the systems i dealt with. But goodluck too you.

well you are correct checked with some one and you could possibly harm your bulbs and ballast if you dont let the ballast cool down so you would need 2 timers and have the ballast shut off first say at 12:00 then at 12:05 have your second timer flip the relay to the other bulb/room. then at 12:10 have your ballast kick back on and would work good.........
