Again I was hopeing someone might have one and be able to share pictures or maybe someone has built there own. From what I know there is no time delay between the switching but I dont really know I have heard these unit use DPDT Relay's I just dont know what kind. Anyways thanks for all that are interested and your replys I have searched and searched and cant find a how to on these things. I asked someone on another site who was selling them if they would share what type of relay and the person got all pissed and said he could not share that info because it hurts retailers. Well I know these relays cant be that expensive and I told the person that they are way over priced just as many grow supplies are. Oh well guess we will never know I would love to buy one open it up find out what makes it tick and return it.........

What Zandor was trying to say is that, the capacitor and the igniter need time to discharge its current load if not you'll probably pop a bulb. But about a flipflop relay all it is is a couple of relays DPDT relays hooked together so that you can have one in and two outs with the same voltage and almost same amperage. Most electricians could build this in no time, I can write you up a schematic if you tell me what exactly you want.
