Need help with light flipper

[mjlover]

So I built a two light flipper using some pretty big relays about 4 yrs ago following someone's diy. I'm not sure if I can find the link or not. My question is they were built to use on 120 circuit. Well I'm currently about to buy some 240 only ballast because I'm getting them for a great price. . I have two 240v outlets installed right now but I would like to flip one ballast on two tents. I'll post pictures of the flipper but is anyone an electrician that could tell me 1. if it's possible to convert my current flipper to 240v or 2. link me to a 240v diy flipper and I could probably figure it out myself. Thanks

I bought 2 ballast that are both 120v and 240v so I can use the light flipper I made on the 120v setting.

Input voltage for ballast doesn't matter, you are switching the lamp outputs, the relay for the flip has a 120V coil.

like hvac guy said... voltage of what ever you are switching does not matter(provided its within the contactor specs).
you just need to buy relays with what ever coil voltage you intend on using.

could buy contactors with 12vdc coils if you really wanted to.

Nice. Thanks guys. I would rather run 240 anyway since I have two 240v lines and would help me sleep better knowing the power is run on those lines vs cramming everything on the 120v circuit
