Hi
I built a double balast with a switch that let me chose between Mh & Hps + 120v output

Then I add in my CoolSun reflector a light bulb socket.

So i plug my timer to the ballast the ventilation on my 120v output so my bult & ventilation is control by the timer.

I put my switch to Mh for vegetation & Hps for flowering

Mh

Hps


Now I don't have to touch the bulb anymore

I also include the electrical plan


Enjoy

Nice work. Can you run both lights at the same time?

Yeah man that looks like a killer setup. If you can run both of the lights without heat being too much of an issue I would do that. It would be like a full spectrum of color for the plants. They would love it to say the least. Great work

Tom
