My lights are dead (or almost caught fire) how long can I go without lights

I have zoos and a hammerhead.

I used the "blackout" method for a cyano breakout some time ago. 3 full days, complete darkness with a blanket wrapped around the tank. Turned the lights back on slowly over 2-3 days, no harm at att (and the cyano was gone).
I would guess I could have gone longer with minimal effects.
 
You could easily go a week with no issues, during the crazy cyclone season corals can get no light for quite a bit. I've gone 2 weeks before with no problems at all.
