What's needed here are instruments that aren't as sexy, but more useful.

-on my projectors I want a readout that tells me the useful lifetime left in the lamp.

On my car how about an engine temperature gauge? My old car had one and as my radiator became congested it kept me out of a world of trouble!

Good idea the lamp hour meter Steve! Cannot imagine it would at all difficult fitting one in series with the lamp circuit via a relay.
All it would need to have is a simple digital hour counter with a reset button taking its trigger from the relay or CT etc.

The only question is do you want it counting down from the rated hours or up from zero with a sticker next to it.

Could be very informative: if you keep blowing lamps with 20 hours left either your lamp voltage is too high or you have ball of cat hair clogging an air passage!

I would want it counting up Steve. The lamps are rated at 50 hours, but they seem to last much much longer now since changing out both the lamp holders for new on the two machines I use the most.

I would still be interested in scientifically measuring this though and it would, as you quite correctly point out Steve, indicate at an early stage when airways etc are becoming blocked or lamp holders are becoming worn again.

I wonder if the counter time is supposed to match this time in as well? Always wondered what this count in is for as well....Tells you when to sit down quick with the popcorn?

The counter on a camera apparently was to tell how much of a 50' reel was left.....you would think the logic would continue onto the actual projector.
