This is my first time I was wondering about safety. If I have a black tarp surrounding my flowering room, could the bulb burn or melt the plastic?

These lights get very hot if they plastic gets to close yes it can.

Are you running any type of reflective hood with this bulb or is it free hanging? If it is free hanging it should not be hung close enough to touch the tarp wall of your room.

If your tarp is Black/White tarp you would be better off flipping it around and using the reflective properties of the white side on your flower room.
