Can I run lights out for 2 and a half days?

I have a SB reeflight (black box) that has a program in it but won't start by itself when its supposed to. I have to manually go through the buttons and essentially restart it. Can I just go lights out for the 60 hours Ill be gone without ill effect to my corals? Two LPS and then just random softies like Zoas and mushrooms.
Please let me know

Should be fine... when corals are shipped... there in a box for hours... even in the wild if itís stormy and heavy cloud cover... there not getting very much light if any at all. Just make sure the water movement is still going and should be fine

Thanks. The cloudy reference in your reply though is incorrect. In the tropics or out on a boat (been in both) the sun may not "be out" but the UV radiation, and thats the wavelength we can't see, will give you a sunburn just as, if not quicker because the UV rays go right through cloud cover(kinda like when I first got powerful LEDs for my tanks, it didn't look as bright as my other lighting but the spectrum, corals use most is unseen by us.
Man. I hope i didn't come off as a lecturing idiot. It just occured to me and I typed it. I will still use your advice , cause I thought it'd be alright but needed feedback from all the folks on here.
Thanks again. Best reefing to ya

3 days lights out is done all the time as a method to help with cyano problems...it causes no problems at all with corals
