Right. After having nothing but small and relatively low tech TVs over the years, we bought a nice, expensive 1080p projector in 2009. It looked great, worked great, we were quite happy with it.
But a few months later, it told us that its bulb needed to be replaced soon. And the replacement was going to cost a couple hundred bucks.
I knew that projectors needed bulb replacements from time to time, but I didn't think it would be that frequent.
We just let it complain until the projector refused to work because of an 'expired' bulb.
I got online and bought a super cheap 'clone' for the bulb from China. After installing it, all was well.
That same bulb was working fine from 2009 until we got rid of that projector in 2018.
- stan_rogers 7y agoThe bulb thing is about colour changes over time - which, admittedly, you may not notice, or may not notice enough for it to bother you at all. (As an old-timey film photographer, I dealt with bulbs both as light sources for shooting and as enlarger light sources. A 100° colour temperature shift isn't all that visible to the unaided eye, but it does make a huge difference where colour criticality matters. My bulbs tended to be good for 10 to 50 hours before they really needed to be swapped, even though they were still clearly bright enough.)
- Diederich 7y agoThat is true, we did notice a slow color shift over the years, but that was fine by us. (:
- Dylan16807 7y agoSounds like something that, in the use case of a projector, you could compensate for in software 90% of the time. (With a sub-dollar chip to crudely measure color temperature.)
