sirquack: Computers are different. If CPU core temperature is not kept cooler than a certain limit the CPU will burn out.
bridgeman: Both my dad and the person who I sold my old infocus X1 has higher numbers and years with their first bulb than for instance my cousins X1 who has already changed the bulb once. I have told my dad and the guy I sold my X1 to cut powr off on the projector. There is still working fine.
Please note these are my personal observations and this is what I do for my setup and it works for me. I can not be responsible if you diminish the life of your bulb by using my methods.
