Can you provide contrast ratio and lumens and expected hours on this item?

Thank you for your query. Generally, lamps used in different projectors have different contrast ratio and lumens because these two parameters are affected by the light tunnel, lens or mirror surface, etc. As for the lifespan of the lamp, the Original lamp has a lifespan of about 1000-15000hours, the Compatible lamp around 800-1000hours. It also depends on how you use them.

These particular ones should be 2500 Lumens. The option may be there for other sellers

Good points all around. Indeed, a new plasma set should be run for the first 100-200 hours at moderate contrast levels in order to allow the phosphors to burn-in more evenly. The higher "dynamic contrast" settings are awful for home use and are really only useful in extremely bright lighting conditions and to get potential customers' attention in the showroom. That being said, the recommended calibration settings above are simply a good starting point for someone who's new to tweaking the settings on their new 42B450.

thank you for the question actually I returned it back as it didnt match my requirements using it in big room, regarding resolution and illumination (lumins units) wish to help you more :)

Produces 1600 lumens and will last an average of 10,000hrs. This was mentioned twice in the product description.

I don't know the specific lumen rating, but the LEDs are fairly bright. That being said, from a distance of 3 to 4 feet, it's a dim overall glow. I planned to use it over a work surface and it just wasn't bright enough. If you are using close up of for general illumination (like a small compartment) it should be okay.

I wouldn't buy it. Mine is no where near a 1000 lumens. Maybe 200 if that. Just my 2 cents.

You can adjust the brightness and the contrast. It also has 300,000 pixels resolution.

You can check Luminessair.com and see their color chart this system is fair which is #2&3, Medium is 3&4. This comes with a DVD and instructional booklet also.

The bulbs specs. are on the bulb. The luminosity factor is on the bulb and on the specs. of the listingj

I would say they are pretty accurate. Doing normal web browsing at 50% brightness could run 8 to 10 hours.
