I'm still fairly new to projectors and was wondering if I should limit my daily usage on it..I understand the bulbs only last for so long, but will I cause more harm by using it 5-7 hours a day??..I'm a huge movie buff and watch at least one movie a day, plus do some gaming and regular tv watching as well...Should I be giving it breaks, to cool down between movies?? Also, I unplug it every night..Is this good for it, or should I just leave it plugged all the time? Thanks guys!!
