Electrical Question 2x1000 Watt Setup

So I have 2x1000 watt ballasts and hoods running in one room on separate circuits. There are two different 15 amp circuits in the room, so it works out. I've been running this setup for about a year now. Never had any problems with it electrically.

Tonight, I was in the room while the lights were on, mixing some nutrients for my veg room plants. All of the sudden, both bulbs/hoods go out at the same time. The fans were still on and when I looked over at the ballasts, the lights for those were still on as well. So basically just the bulbs went out at the same exact time, even though they're on completely different circuits/hoods/receptacles etc. I've never seen or heard of anything like that happening before, and was wondering if anyone knows why that might've happened? After unplugging both lights for about 10-15 mins, I plugged them back in and everything worked just the same as before.

Maybe just as simple as small power surge, and it was just too fast for me to hear the fans dim down, etc.?

are u in a home
15 amp nice someone thought ahead
odds are the power grid had a demand or something got rerouted

the breakers did not pop ?


ummm i know of one other reason they do that but unless u think ghost are possible ....u are not going to care about that possible choice

There are a few determining factors, could have been a power draw elsewhere, but you would generally notice a dimming of the bulb an instant before loss of light....if they are identical hoods/lights check to see if there is to much heat....by that I mean, are the ballasts next to each other, are they (and bulbs/hoods) getting good air venting/cooling? Check your timer also....I once had a problem similar to that with lights going out....took a meter to everything, dismantled the balasts, checked EVERYTHING down to its basic component......and then I realized I was so high it would seem I didn't know which 12 hour cycle i was working with....

Electrical in the US runs on 60 cycle AC....
That means the current alternates 60 cycles a second...
So your power goes out for 1/60 th of a second...
It happens all the time... you'd be surprised...
Fans didn't miss a beat...the motor loosing power for 1/60th of a second you would not of heard....
Ballast lost power and of course go out, then they came on no problem...
A Power Line spike most likely ...
IMO... You are good to go and not worry...

And I might add, kinda smart, cause you figured it out by yourself, and didn't jump to a crazy conclusion....

Although, it would have been cool to hear it was aliens....

It's called a brownout.
