A few questions before I make the switch.

My greatest concern is longevity. My TV is on anywhere from 8 to 14 hours a day, and even with over 5,000 hours on it, it still looks as good and evenly bright as the day I bought it. Basically, how many backup bulbs should I have on hand? As I understand it, the life of identical bulbs can vary by dozens or hundreds of hours.

I noticed some projectors are marketed as "2D/3D" instead of just "3D." What's the difference?

As I don't care about 3D, is there a no frills high image quality 2D-only 1080 or 4K projector?

You only have 5000 hours on your TV???? My 3.5 year old set is probably closer to 14,000 by now (But I work from home and use it like a radio).

Bulb life can vary by manufacturer. As does cost of the replacement bulb. You can also extend the life of a bulb by using it in 'Eco' mode in instances where full brightness is not needed.

I never keep more than one back up on hand.

I share your concern about lamps and longevity. It is what keeps me from upgrading to a better projector.

So you do 8 to 14 hours a day, or 2950 lamp hours on the low side or 5110 on the high side. Getting a projector with a lamp that runs $300 could cost you $300 or more a year. My solution was to get a Epson HC2000 with $99 replacement lamps but you take a hit on contrast/black levels. Most media is fine but if you are a horror fan like we are dark images/scenes could be better, but it is a trade off. We have a $549 projector with a lamp rated to 5000 or 6000 hours, and a two year overnight warranty....but, the image isn't for everyone.

2D to 3D: some projectors convert 2D to a "3D" image.

Keep in mind your room will also impact the image. In a bright room the image will be washed out and any light lowers contrast. For example, my 169inch 16:9 image before I treated the room with 7 hundred watt lights on, 1 hundred watt lamp on and all lights off.
