Tyler Perry Sues -- Heller!!! Y'All Tried to Burn Down My Studio

Tyler Perry is blaming bad lighting for a disastrous fire at his massive studio complex in Atlanta ... and now he wants the producers of a sitcom to foot the bill.

Perry filed a lawsuit -- obtained by TMZ -- claiming the blaze broke out in May 2012 during production of "For Better or Worse" ... because a white hot light was placed too close to a facade on the set.

Perry -- who obviously knows his way around a studio -- is suing the show's producers for negligence ... saying they should have had better lighting guys.

He's demanding $1.8 mil to cover the total damage to the studio.
