I've recently got myself an Infocus 4805 with which I'm very pleased. Reading reviews etc. suggest that bulb life in economy mode can be up to 4000 hours. Trouble is, the internal timer will stop the thing working at 3000 hours anyway. So presumably you need to reset the bulb hours timer before the 3000 tottal is reached? What are the risks in doing this? Is it more likely the bulb will explode, is the projector at risk at all from doing this? Am I at risk from doing this? If it is safe to play with the bulb life timer, why do manuafaturers shut down the projector at a fixed point? Will appreciate any advice. Cheers, Bob.
