Day 61 indoor- Are the plants getting light?

Day 61 indoor- I’ve been feeling a little uneasy about the light inside the tent. I can’t shake this feeling that they’re not getting the 12 hours “on” for some reason. I should make sure to listen to my intuition in the future because the light has NOT been on these past two nights. Apparently the light turns off shortly after you turn it on; I must’ve zipped the tent up before it turned off last night. Tonight though the light is turning off within seconds. I can’t trust the light to stay lit so…one more day in the dark I guess. That 36 hour darkness has turned into much more and I’m pretty upset to be honest. I don’t know if I should bring the plants outside and cut my losses inside? I don’t want to do that because I’ve worked so hard to get to here. It’s really late at night and there’s nothing I can do now; I’ll have until 6pm tomorrow to figure something out. Ugh!!
