The brightness of a laser projector decreases at a constant rate, while the brightness of a lamp-based projector decreases rapidly at first and then slows down. At least the lamp-based can be replaced.
There's a graph of this dimming rate out there.

Laser projectors, including those like the Epson LS11000, generally experience very little dimming over time compared to traditional lamp-based projectors. Here's an overview of the typical dimming rate:
- Gradual Dimming:
- Laser light sources typically lose about 20-25% of their brightness over their rated lifespan, which is often around 20,000 to 30,000 hours. Unlike traditional lamps, which can dim significantly (up to 50%) within just a few thousand hours, laser projectors maintain a much more consistent brightness for the majority of their lifespan(
- Uniform Dimming:
- The dimming occurs slowly and uniformly, meaning that users are less likely to notice any sudden drop in brightness until the laser reaches the end of its operational life. The projector is still usable after that, but the reduced brightness may affect the image quality, especially in rooms with ambient light(
Overall, laser projectors provide much more consistent performance compared to traditional lamp-based models, making them a preferred option for users looking for a long-lasting, reliable light source.Projector Reviews

But then if we go back to my original post, I was was asking how many hours left on this refurb because none is stated. You'd want to know how much degradation is already there. I think this is a fair question to know.
At $2799 refurb LS1100-, you can get a brandnew 5050UB which is brighter and has deeper blacks and still have a spare change for you to buy 2-4 spare bulbs which is good for additional 5-7 yr depending on your usage.

$2400 for 5050UB is not the best price if I am not mistaken. I think sometimes, you see it lower..
To make a fair comparison, purchasing from places like Amazon Marketplace won't get you a warranty from Epson. This deal, however, is directly from Epson and includes a 2-year warranty. You can also add an extra year for $315.
As for the comment that "bulbs lose brightness initially, but degrade slower than laser and then burn out," I disagree. Bulbs tend to lose brightness quickly, while lasers maintain their brightness much longer.
My point is that there are several other issues that can crop up BEFORE the laser fails.
Also - more and more Manufacturers are moving to Laser. Bulb will face death eventually.
