I am new on the projector scene so please forgive me if this is a silly question. I have a BenQ W2000 and on the data sheet it states... Lamp Mode (Normal/Eco/SmartEco/LampSave)* 3500 / 5000 / 6000 hours In Smart Eco mode the lamp timer goes up by 1x, Eco mode by 1.4x and normal is 2x In SmartEco does the lamp timer progress evenly at 1x or does it vary depending on how bright a scene is? I.e does the timer progress by 2x on bright scenes and 1x on dark scenes? Also how safe are bulbs? I don't want to use SmartEco and stretch the bulb timer to 6000 hours and risk the bulb exploding and ruining the projector. But on the flip side the manufacture must deem it safe to stretch the bulb timer this far in SmartEco?
