Is my grow jeopardized?

I went to check on my plants this morning, only to find out that my neighbors left the incandescent light on all night. (They have a switch in their portion of the house also. I have removed the bulb so this won't happen in the future.) My plants have been in flowering for about 5 weeks now. How detrimental is this going to be to my grow?

If it wasn't on for more than 2 days I don't think it will have any impact on it besides a 1 day delay at most.

Awesome, thank you.
